hi All,could a hardware prob. be causing FSX to crash with "terrain.dll" being the culprit? (according to Event Viewer) also, sometimes the computer will restart on its own during a flight with FSX. i'm using the PMDG 747X with FS2Crew and RCv4. all scenery and weather(RWW) is stock FSX. a few days ago i turned the computer on and the case fans were running but the computer did nothing. no BIOS Splash screen or POST msg., no BIOS beep codes no nothing. it was like the case fans were the only thing getting power. i turned the computer off using the PSU on/off switch. turned off the UPS battery back-ups surge protector and waited several minutes. then i turned everything back on turned the computer back on WindowsXP Pro X-64 booted fine. only prob. was less than 1/2 a minute after the desktop appeared the computer reboots itself without any input from me. i've ran Spybot S&D and Ad-Aware AE and neither finds anything. spyware/adware doesn't appear to be the prob. all this is happening with a less than 3 wk. old clean WINXP Pro X-64 install. thanks in advance for any and all help. happy flyin, FM

FlyinMisfit (?),I choose to read your post since the header indicated that you have problems with CTDs in FSX. This is obviously not the case.You seem to have a problem with a hardware failure. What component could it be? The motherboard or the psu or? Maybe even the right time build yourself a new computer?You have checked that power and other connectors on your motherboard are correctly connected? The graphics card hasn't partly disconnected from the mobo slot?

Typically this is an indication of a hard crash, usually memory related but can be from the PSU/CPU, etcTo verify if there is a error message or a hard crash you need to shut down the automatic reboot feature in Windows which will then allow a BSOD to show instead of rebooting. If you still get a reboot with no BSOD then you are definitely dealing with a hardware failure issue.. again, usually memory or voltage relatedCONTROL PANEL - SYSTEM - ADVANCED TAB - STARTUP AND RECOVERY BUTTONUncheck "Automatic Restartclick OKFrom now on you should see a BSOD with a error message when this happens... that message will then point to the culprit or at least start the process of diagnosis. If no BSOD is seen then its hardware

thanks to everyone who replied. i was hoping you would chime in Nick. last Sat. night was when the computer itself did not come on (case fans only). since then that has not occurred again. i was making a flight in FSX yesterday and less than 2 hrs. into the flight the game crashed. according to Event Viewer "terrain.dll" was what caused it. i've made a few flights with FS9 in the last month or so with no probs. however, with FSX there's been quite a few times when when the game would crash or the computer just rebooted itself during gameplay. both FSX install discs as well as my driver/patch backup discs are free of scratches and finger prints. in your post you mentioned soemthing about voltage probs. is that Mobo. or PSU voltage? i just recently replaced the Memory and that didn't fix the prob. i will try the Windows "no restart" thingy as per your suggestion. i've checked All connections and no probs there. below is my Sys. Specs. that i should have included in my original post...ASUS P5E3 Deluxe WI-FI Mobo. BIOS Ver. 1203Enermax Galaxy 850W PSUQX9650 EXTREME O/C to 3.7Ghz. (via Multiplier only)4GB Mushkin DDR3 1333 Mem.WD Raptor 150GBATI 4870 1GB Mem. Cat. 9.4SB X-FI X-treme Fatality ProWINXP (64-bit) w/SP2latest DirectX 9.0c for XP64latest Intel Chipset Update for the P5E3btw Nick, will the Core i-7 965 offer any improvement in visuals and or smoothness over the QX9650 Extreme that i'm currently using? if memory serves me correctly i think i read somewhere that you mentioned that the i-7's at the same clock speed didn't increase the FPS that much if any at all.thanks again for your help and to Everyone else. happy flyin, FM

as I said.. rebooting in the middle of gameplay is a crash however if the system is not set to show you the BSOD you do not have an error to work with, which is why I said to change the STARTUP and RECOVERY settingsIf it still reboots with NO BSOD it is in fact a HARDWARE failure.. most likely the memory which can be memory voltage too low.. or a CLOCK that is not stableIt can also be another device failingbut you have to start somewhere and that is seeing if there is a BSOD associated with the reboot which is what that AUTOMATIC RESTART change will allow

sorry about being late in responding Nick.i understand the part about trying to get the BSOD by disabling the Auto. Restart setting in the Windows Startup and Recovery settings. i had a spare Mobo laying around so i decided to pop it in & see what happens. too impatient i guess. i don't know about you but i'm leaning more in the direction of it being a Hardware Prob. of some sort. as mentioned earlier i tried replacing the Memory first and that didn't fix the problem. at least one item has been eliminated so far. i will report back in a few days (or less) and give you an update.in case you missed it in my previous post, will the Core i-7 965 offer any improvement in the visuals (FSX) over the QX9650 Extreme at 3.7Ghz that i'm currently using? if memory serves me correctly i think i read somewhere that you mentioned that the i-7's at the same clock speed didn't increase the FPS that much if any at all.thanks again for your help. much appreciated happy flyin, FM

With a ATI card?HmmmmmmWell.. what I said is the user will have more OVERHEAD to work with so yes there would be a defined increase in perf running i7 however in your case for FSX you would also need to dump that ATi card which is not going to help you at all in such an upgrade.. if anything it will drag down the benefits

yeah i know....the dreaded ATI card. it's a shame ATI's cards beginning with the 1800 series (if memory serves me correctly) started going downhill esepecially with their AA. for me their last Good card was the X850XTX. my first ATI card was the Radeon 9700 and i've been hooked on ATI since then. if their next round of cards aren't a major improvement over their 3000/4000 series cards i may very well give the Nvidia cards another try. again, thanks for your help. happy flyin, FM

Lets not get the wrong idea... ATi uses a DIFFERENT method of AA and their core and card designs are geard toward the modern SHADER based rendering enginesThey can be great cards but the application of choice here is MSFS, a year 2000 TRIANGLE rendering engine that requires raw horsepower over shader optimized code to overcome which Nvidia is still catering to in its designsThat is why ATi is worse than Nvidia in MSFS.. although their 3 series was a real bomb (and I dont mean that as in "the bomb" LOL)Eventually we are all going to be screwed regardless of the card as newer designs leave those old game rendering methods behind.. its already started.. right now we are seeing it can take 2 years before a Nvidia card shows results worth upgrading for in MSFS.. ie; 8800GTX to the 280GTX

hi Nick,just in case you were wondering, i didn't take your comment regarding the dumping of the ATI card personal. i apologize if my "yeah i know the dreaded ATI card" comment in my previous post came across that way. just a little humor. in reference to ATI's cards, i knew something had changed along the way i just didn't know what. imho, the 4870 doesen't seem to be much better (especially with FSX) than the 3870. i've used both with it. it would've been nice if MS had gone with a more modern rendering engine for FS years ago. i hope that MS will keep the FS franchise alive but i'm not holding my breath on that one. happy flyin, FM

well Nick, 5-6 hrs. into the flight today the computer restarted again during a flight with FSX. i had the AutoRestart disabled in Windows (per your suggestion) and the computer restarted instead of giving me a BSOD. to this point 2 items appears to have been eliminated as the potential prob. - Mem. and Mobo. what would u suggest i try replacing next, PSU or CPU? also, is it possible that my UPS surge protecter could be the prob.? i don't know that much about those things. according to the owners manual for the Enermax Galaxy 850W PSU that i have it recommends using a Sine Wave type (whatever that is) UPS unit which is what i have. and, that it's not compatible with a Simulate Sine Wave type.again, thanks in advance for your help. i was hoping to have better news for you. happy flyin, FM

What makes you think the mem is not the issueand how do you know your clock settings are not the problemthis is a hard failure and in most cases such reboots are memory failure.. could be settings in the clock directly related to memory stability too however unless this happens when your system is set to DEFAULT, no clocking at all, you are probably not looking at a PSU.. although there is what I would consider a very 'outside' chance of a PSU.My money is on the clock settings and/or unstable -or-defective memoryunless this PSU is not very strong and was underspec'd to begin withwhat are the PSU specs.. link it

Nick, here is the link to the PSU specs taken from Enermax's site........http://www.enermaxusa.com/catalog/product_info.php?cPath=21_49&products_id=115as for the memory, i was first using the Corsair XMSDDR3 1333 at 9-9-9-24 @ 1.7 volts. (Corsairs rec. voltage at those timings) 2 x 1GB sticks. a month or two later i decided to lower the timings to 8-8-8-20 @ 1.9 volts. and, that's when i had the first restart with FSX. i dl'd. MemTest86 (lastest version) that runs from within DOS from a 3.5 floppy 8-10 hrs. straight with no errors. i'm currently using new Mem. (less than 1 mo. old) Mushkin DDR3 1333 8-8-8-20 @ 1.7 volts (Mushkin recs. 1.7-1.8 volts) 2 x 2GB sticks with FSX still crashing or the PC restarting - with 2 different Mobos. i haven't had a chance yet to check the Mushkin with MemTest. i know that MemTest is not 100% accurate. that's why i replaced the Corsair Mem. with the Mushkin. in case you may have forgotten, my full Sys. Spec.'s is a few posts above in this thread. let me know if u need any further info., spec.'s or otherwise. thanks for the help. btw, i decided to play it safe with the Mushkin. in the BIOS, DRAM FREQ. is set to Auto, DRAM TIMING CONTROL is set to AUTO & the DRAM VOLTAGE is set to 1.7 volts manually. according to the BIOS info. the Mushkin Mem. is running at 1333Mhz. when i was using the Corsair Mem. the DRAM FREQ. was set to 1333Mhz manually as well as the timings at 1.7 volts(9-9-9-24), 1.9 volts(8-8-8-20) and, according to the BIOS info. the Corsair Mem. "was" running at 1333 Mhz. happy flyin, FM

Just an FYIWhen upgrading the BIOS on the P5E3 Deluxe there is a specific order that must be followed.. even Asus notes that which is not something they typically do.After a BIOS flash the user must power down completely.. (Power OFF) for about 10 seconds, then (Power ON) - restart, enter the BIOS and at the exit screen, select LOAD SETUP DEFAULTS then F-10 save and exit and allow a reboot.. then enter the BIOS and set it up.If that procedure is not followed the BIOS will not update correctly which can lead to instability problems.That is how I update -any- BIOS and have for years.. in this case Asus specifies that process for a reason. Latest BIOS is 1409 but it is BETA according to the websiteP5E3 Deluxe/WiFi-AP@n BIOS 14091. Enhance compatibility with certain memory modules. Last Official BIOS was 1303P5E3 Deluxe/WiFi-AP@n BIOS 1303In order for Express Gate to function with this version of BIOS, please update Express Gate to version 1.2.0.0 or laterSupport new CPUs. I doubt the PSU is the issue here. Although a defect is possible its certainly not a power issue from an overtaxed PSU.Using CPUz check the SPD tab and set the dropdown to a populated slot.. post the exact model number of this memory and if possible the CPU, Mainboard, Memory and SPD CPUz tabs with data

hi Nick,i did follow that prcedure with at least 1 maybe 2 BIOS updates (can't remeber if it was one or two of them) that included that procedure posted with the BIOS file(s) at the time of posting. the one that is currently installed (1203) did not have that procedure posted with the 1203 file so i did not use that procedure with the 1203 update. i did not know that it was required for all until reading this post. the BIOS update that requires the Express Gate utility to be updated i did not bother with that one because i have Express Gate disabled anyway. and, i've never updated a BIOS utility b4 and i was concerned that if i botched the update the board might be useless. i hope the screenshots of the CPUz info. you requested show up in this post. not very good at this sort of thing either but i will give it a try. so here they are (hopefully)

OK.. give me the memory tab.. you got them all but the MEMORY tabEDIT: You have SPEEDSTEP running.. thats a NO NO when clocking.. do you also have LOAD LINE CALIBRATION: DISABLED?ADVANCE CPU MENU - SHUT IT ALL DOWNDisable all the CPU crap under the Advanced CPU Configuration menu

here you go Nick. sorry about that. SPEEDSTEP is disabled. also,the CPU voltage is manually set to 1.29375 volts. i'm a little confused here. the other CPU settings that you mentioned that should be disabled when o/c'g has been enabled since i've had this setup. and, i haven't had any of the probs. that i'm having now except for early last year when i tried lowering the Mem. timings to 8-8-8-20 and after going back to the 9-9-9-24 timings i've had no more probs. until the last month or so. and nothing has been changed since setting the Mem. timings back to the triple 9 timings. i do remember reading in one of my Maximum PC mags. prior to getting the QX9650 Extreme that SPEEDSTEP should be disabled when o/c'g Any of the Core2 procs. but they didn't mention anything about disabling the settings that you mentioned in your above post. and, i'm not saying that your wrong and their right. all of this is driving me nuts. there doesn't seem to be a pattern of any kind at all with this mess. thanks for all the help. happy flyin, FM

Go back up and look at your CPU speed2GHz?look at the multiplier6x?look at the Vcore.. 1.25?Your processor is being controlled by power management which includes speedstep and CE1That is a source of instability and although I am not saying that is your problem no self respecting clocker leaves those advanced CPU features ENABLED due to how the fluctuations can create strage problems however you are welcome to do as you wish.Muskin specifies 1.80v completely safe for 991652 modules which is what I would set them toFind LOAD LINE CALIBRATION and ENABLE it, then set the CPU vcore to 1.28-1.30 manually.. but I would shut down at the very least CE supoport to keep power management from contolling the multiplier and voltage. CPUz should show you the full 3.7GHz clock and vcore you set in the BIOSWhat is your CPU VTT set to in the BIOS? (AKA: FSB Termination Voltage) AUTO?If so, set it to 1.28vCPU PLL voltage to 1.50vWhat is the NB Voltage set to in the BIOS? Auto?Try 1.40v

Nick, i will give All of those settings a try and see what happens. as i mentioned in my previous post the CPU voltage is manually set to 1.29375 volts. i don't think the LoadLine Calibration setting is in the BIOS but i will double check and if it is i will enable it and set the Mem. voltage to 1.8 volts as well. if possible, i'll make another flight in FSX this weekend and let you know how it goes. thanks again for all of your time and help. happy flyin, FMupdate-Nick, the BIOS settings you suggested in your previous post has been applied. the Load Line Calibration setting was in there & is Enabled. below is a shot of the CPU tab in CPUz after your recommended settings were applied. notice the CPU voltage - it's still not showing the CPU voltage of 1.29375v that the CPU voltage is Manually set to in the BIOS. is this a prob.? if so, is it a Mobo. or PSU prob? or neither? however, the voltage is not fluctuating up and down in CPUz like it was prior to your settings being applied. i'm assuming because i disabled C1E Support. btw, so much for trying a flight in FSX this wknd. i suppose. this idiot PC restarted itself again in the middle of posting this info. and when Windows booted after the restart Windows wasn't working. i had to shut down the PC via the PSU power switch and reboot. so i decided to put your suggested settings in your previous post back to default except for the C1E Support which i left disabled. you wouldn't happen to know where i could find a stick of Dynamite rather quickly would ya? happy flyin, FM
