Only a group like this would appreciate this...So I spent the last week traveling from NY-Chicago-Milwaukee-Chicago-Brussels-Chicago-NY on business. My FS rig spent the week shut down which is probably the longest she has been shut down since I built her LOL...I got home at 1am Friday morning and passed out exhausted. Naturally I woke up 5 hours later Friday morning at 6am ready for work but also ready to recreate my trip. I fire up my main FS rig (OC'd to 4.5 on liquid at 1.45V on an E8500) and as soon as everything starts to spool up it shuts down. Confused I try to power up again but this time it was a split second on/off and she shut down again. OK, I can handle this, no panic yet; maybe she is telling me she doesn't like to be left alone...I simply flip this BIOS reset on the back of the case and fire her up. I immediately start getting over-voltage and overtemp warnings on the CPU. Hmmmm Now my heart is beating a little bit, did I fry my processor? What the heck is going on. I bet it is self induced ... So I enter the BIOS and see my CPU temp at 93C HOLY CR*P pull the plug pull the plug! So I shut her down and think that couldn't be right, it had to be a mistake or I misread it and go to fire her up again with default settings and it shuts down immediately. 90C cutoff warning probably. So now I am really panicking and have to regroup as to how to troubleshoot.OK, what could it be? Processor is fried? Mobo is fried? Maybe the house got cold when I was away and it affected the thermal paste? Maybe the pump in the liquid system is not working? Where to start???KISS Keep it simple stupid...So I start with the easiest fix. Unseat processor and liquid system, clean all the thermal paste off using 91% rubbing alcohol and then reapply the Arctic Silver Liquid Ceramic. Re-seat everything, hook the liquid back up and test. Immediately I start getting power cycles on and off. When I do get back into the Bios after a few frustrating tries I see the CPU is pinned at 89C again. Pull the plug pull the plug pull the plug LOL so I don't cry...OK, rule out thermal paste. But how do I test if it is the mobo or CPU if I can't get the system up and running.. In comes the backup systems in all their glory!!! Suit up team we need you!Unseat the liquid system and CPU again clean them both off again. Remove the Fan and CPU from the back up system and clean them off too. Mind you, at this point all the equipment is free of thermal paste and liquid ceramic but I am COVERED in it. All over my hands, my shirt, my pants the floor the desk and anywhere else in the house I happened to roam while this was all going on....Back to the troubleshooting. I now reapply the liquid ceramic to the E8500 but mount it into the backup system which was an E6600 so fortunately it pops right in. Put the fan back in and fire her up and she come right up at 54C on air. A little warm but certainly not 90C and I am not sure the fan was even seated 100%. OK, So it isn't the CPU. First time I wipe the sweat from my brow all day...But as soon as I breathe a sigh of relief I realize it must be my $350 motherboard, D*mn the processor would have been cheaper and easier so now I am sweating again...Take the E6600 and pop it into the primary rig, apply more ceramic, get more all over the place, seat the CPU hook up the liquid fire her up and nada...OK, this is weird, I figured I would get something out of the mobo even if I had pushed it too hard which would really surprise me with my settings anyway... Try to power her on 3 or 4 more times and she is like an old car on a cold winter day that just wont turn over at all. Take the E6600 back out, clean again, take the E8500 out again, clean again and sit dumbfounded for a while.And then it hit me (sang to the tune of the classic "and then she kissed me") Power supply....By this time it is like 5 pm already and getting dark btw... Quick, get the backup system up and running so I can Google what stores have a 1k power supply locally. (yeah right lol)More Ceramic, more mess, reseat the 6600, hook up the fan and go. Well Best Buy has an 850W so maybe that will work. Drive as fast as possible in pouring rain to Best Buy (20 minutes away) and get an 850W power supply (woo-hoo, little victory) Drive home as fast as possible in pouring rain to realize 850W does not have quad PCIE connectors but Dual. ARRRRRGGGGHHHHHH! Are you kidding me? I can't just pull out a video card for testing they are linked by a liquid connector and essentially linked as 1... Ok, ok, there has to be a way...Hmmm, the backup system has a power supply, it has dual PCIE connectors but I am using an 8600 card that doesn't even use them. What if I powered down both systems, took the PCIE connectors from system 2 and hooked them to system 1 and then powered them both up? Oh well, only one way to find out... What's the worst that could happen LOL ;)....Well, believe it or not, it worked LOL AND when I did boot and get into the BIOS the same 8500 that was running @90C + was happily purring along at 33C. So, after everything it was the power supply! But this little conjoined twins setup sharing power supplies I have going is not a long term solution so it is back to the web. Now it is 6:50pm and Tiger Direct ships until 7pm. I get them on the phone and beg and beg for Saturday delivery but no such luck. So deflated I accept the fact I will have no system for a few days. The recreation of my trip will have to wait. That is until I remember New York City is only an hour away... I think you all know where this is going...Back to Google for Computer stores in New York City and up comes Data Vision and JR Music. Both of which have 1k, 1300 and 1600W units in stock in the NY stores and they open at 9am on Saturdays (I love NY, again, sing it out loud everyone). Order a unit from DV online for in store pickup and for the first time believe I might have found a fix :).Set the alarm for 7am so I am on the road by 7:45 and at the store by 9 because as expected, it is POURING again LOL. After a quick hour drive door to door into NYC, a pickup at DataVision, a 45 minute drive back to Best Buy to return the 850, 25 minutes home and 28 hours after this all started I am actually back at home with a brand new 1K Corsair Power supply. With no time wasted I am into the box so fast you could have missed it with a slow motion camera. Pull it out, seat it, hook up the 19 connections inside the case which is not an easy task in itself btw, we all know these things aren't made for human hands and there are little case monsters that bite and scratch your hands every time you stick them in. Double check and triple check all the connections, nope, didn't miss anything... All I can do now is power up.And.....................Success!!!!! Boots up no issues first time. No Overvoltage warnings no overtemp warnings, no errors at all, right into BIOS and.... 33C Sweet!!!! Do a happy dance... reload my OC profile from the Asus Bios, reboot and poofa I am back up and running at 4.5 everything looks good, temps are great and if I would have gone to the lowest common denominator first (the power...) I could have saved myself 28 hours of frustration, anxiety, tears and 42 more days of trying to get the thermal paste cleaned up LOL...Oh well, I thought I would share as only a group of simmers like myself could EVER understand what I went through!!!All the best everyone, back to the skies :)-PaulOh yeah, there is a moral... A bad power supply can literally cause your temps to skyrocket. I would have never guessed and when I asked frozencpu and koolance in the middle of all this they both said no way could it be the power supply LOL...Primary RigLiquid CooledIntel C2D E8500 468X9.5 @ 4.45Asus Maximus Extreme4 gigs OCZ Reaper DDR3 @1400Dual OC'd XFX 8800GTX @ 2 gigsDual VelociRaptor 10k 3gb/s RAID-0Dual WD Caviar 500 gig Raid-0Single 150Gig SATA2 Swap Drive28 inch LCD 16XAA/16XAFDual 19 inch LCD'sPCPower and Cooling 1k Quad SLISaitek Yoke, Saitek Rudders, Go-Flight Flap,Gear and Trim Controlhttp://home.comcast.net/~psolk/3monitorsa.htmlBackup RigsIntel E6600 @ 3.2Asus P5N32E-SLI Plus3 Gigs Kingston Hyper XXFX 8600 GTAMD 4000 San Diego @ 2.72 Gigs Kingston Corsair XMS CL2XFX 7900 GTX Raid-0
