Please view My sig for details, Home built dedicated only to flight simming no pdf viewers, no print drivers, NOTHING unless its FSX. Here is My problem...very randomly My screens will all go the same color (random each time) audio plays but does not sound like its looping just continues to play, hard to tell with aircraft engine sound witch i guess loops anyway. caps lock key works for about 45 sec. and then nothing..cant get to task manager, ctrl, alt, del. does not work, have to hold the power button in for 15 sec to restart and then the "windows didn't shut down properly" screen "what do you want to do?"...start Windows normally....Don't know if its cpu, video, or what the heck it is..Anybody know of a way to tell?? TIA.

what the wattage of psu....maybe heat problem...

Oops, forgot that one. Its a 1000 watt Antec. The CPU/GPU temps. appear to be within Manufatures specs. i.e. 80% of max. I can't get a snapshot of conditions at crash I wish I could that would lead Me to the Problem....maybe an app that logs this info???

This happens quite a bit with a lot of systems. First thing I would check is the memory. Run a memory diagnostics (Start>Administrative Tools>Windows Memory Diagnostics). It will run two tests at startup and advise if there's a hardware issue. If there's an error, open up the bios and check the memory settings and make sure they do not exceed their specs (whenever I set up automatic overclocking for my system, the bios would overclock my memory past the specs for my memory and I subsequently suffered several BSODs/computer freezes until I discovered it was a memory issue). You can also look in the Event Viewer and see if there was a critical error at the time of each crash and it might describe what .dll or system file that caused it. It could be a bad install of the system sound drivers or display drivers but company's have gotten better with their installation so this is less likely (yet it fixed similar problems like this several years ago). You could have had a BSOD and it just didn't display properly as your system froze up before the blue screen could show up. Google Blue Screen Viewer, download it, and run it. If you have ever had a blue screen, this program will show all the details including the exact driver or file that caused the crash. You can do like I have and simply Google the driver that caused the crash and you should find a solution with one of the many offered links. If it shows ntoskrnl.exe, rest assured it's a problem with your memory settings!! Hope this helps.Best regards,Jim
