Harddrives: 2 x sata harddrives samnsung hd321kj & samsung hd502ij (didnt try yet with just 1 drive)
Acer h2d5h monitor ( on pnp and not running the acer driver coz i cant find any Windows 7 drivers)
Graphics card: single asus gtx 280 (tried Windows 7 default installed drivers, tried asus own latest drivers. Tried nvidia 258.96_desktop_win7_winvista_64bit_international_whql and 260.99_desktop_win7_winvista_64bit_international_whql)

About the crashes:
The crashes, pc unresponsive and have to reset the computer, im getting are that my screen is filled with collored squares, also the mouse pointer turns in to a white-ish square. At least they look like small squares but could also together form diagonal lines if you look closer.
I've never seen weird graphical artifacts in games before crashes.
I never get a blue screen. When my pc crashes my screen is just filled with , most of the time green, small squares and becomes unresponsive. Sound plays on till it gets garbled and my pc also never automatically reboots. I have to reboot it myself even though i have my pc configured as creating a minidump file and then reboot itself. It never really creates any minidump files though, just kernal dump files.
This started to happen over a month ago mostly when i played the game dark age of camelot. However playing bad company 2, pretty graphic intensive game, and civilization V i didnt seem to have that problem. At that time my pc needed some serious cooling and was overheating alot back then. I was running vista 64 bit and ordered my coolermaster haf 932 case with thermalright cpu cooler etc. There was also loads of dust in my case.
When i took apart my pc and installed all my hardware in my new haf 932 case i cleaned out everything from dust first with compressed air. Also cleaned old cooler paste from cpu and applied new paste.
Later the problem started to spread. Also at times giving me the same crash in bad company 2 but so far only occasionally and so far never in civ 5. Even worse. after i'd start up the pc it would start to give me the same crashes when i'd open up the msn window, strange, or start VLC mediaplayer to play video's.
I'd have to reset the pc like 4 times before the crashes would finally dissapear. At times somehow powering down the pc and then restarting it seemed to help ?
I could then use my pc for hours without a problem till i would start a game and then i'd crash again.
Other times the crashes would dissapear for 2 days and then come back as often as they appeared before.
Action's ive taken:
Used Verifier.exe but after a bunch of reboots it never gave me any error.
Did a memtest86 run over night but never gave me any error.
Ran OCCT stresstests but never gave me any error.
Ran Furmark stresstest and left it running with my gtx280 at max temps for 15 mins, about 105 celcius, but never gave me any error.
Ran prime95 overnight, for over 6 hours, but never gave me any error.
Installed the mentioned nvidia etc drivers a bunch of times , used driversweep in safemode.
Disabled TDR in registry but still get errors. Tried to set TDR on 8 sec but still get crashes. With TDR disabled i do notice i get a blank screen at times for 2 seconds while playing bad company 2, just it doesnt crash.
Reset pagefiles but still get crashes.
Ran Harddrive diagnostics (everything fixed if there was anything to fix) on both game partition and C: but still get crashes.
Did a SFC.exe /scannow but this didnt give me any results, no problems.
Tried disabling AERO but still getting crashes.
Used the directx webupdate but still get crashes.
Removed alot of programs like asus utilities, daemon lite etc and removed the files/services or disabled them.
Renamed nvlddmkm in system drivers dir to .old and put in, and expanded, the one from the NVIDIA dir but still get crashes.
Uninstalled old graphics drivers and installed/reinstalled new ones using this guide nVidia Driver Cleanup Guide !! « Captain Debugger
still get crashes.
Went into bios and set cpu voltages and whatever settings manually, sorry cant find that post again, to be sure that nothing is overclocked but still get crashes. I also get the crashes in default bios settings.
Removed ram memory sticks to see if that would solve the crashes but still getting the crashes.
Updated bios to latest version but still get crashes. Old version, default version, gave crashes too.
Set monitor timings etc but still get crashes. I have 2 dvi ports on my graphics card but when i plug my monitor on 1 dvi i loose display alot, goes blank, but on the other port it doesnt happen.
Actions i've not taken:
Use some meter to check voltages.
Open my gtx280 to check its paste or whatever dust etc.
Replace my graphics card with another.
Use a stresstest for my powersupply.
My system runs idle at 30 to 40 celcius on all cores. Maybe reaches 50 celcius under full load.
My graphics card runs idle at 47ish celcius. Reaches about 80ish celcius under full load, for instance playing bad company 2 on full detail settings. Fans turn on to 100% then.
cpu vcore 1.26
+3.3v = 3.38v
+5v = 5.02v
+12v = 11.65v and lowest i've ever seen it go is 11.60v
I've had my os clean of any stuff running in the background except soundmax audio software and currently have running logitech mouse software, soundmax audio, search and destroy anti spyware/virus and acer display management software.
So far i've only 1 minidump in my minidump folders but do have alot of dump files in my LiveKernalReports/watchdog folder.
Always the error the livekernalreports displays, using bluescreenviewer, has to do with nvlddmkm
Installed the tools for windebug and the debug always gives an error with TDR timeout. Must say though i dont really have a clue if im using the debugger right.
Anyway im not sure which minidump files to attach since i only have 1 old minidump and many kernaldump files.
Ill also attach a CPU-Z report and a CPUID Hardware monitor report. Also attached an older , the only one in the dir, minidump file (102610-32354-01) from 26th october and the 5 most recent kernaldump files.
I would suspect the problem is my graphics card or memory but they withstand the stresstests without any problem or removing ram memory sticks doesnt solve the problem either.
Anyway thanx alot upfront for the help.
