(build in sig) I've been having problems with my PC for about 6 months now (ever since I built it, really), but they were never severe until recently. Here are the symptoms:
1. When I turn the PC on - especially in cold temperatures, like winter - it gives me all kinds of strange problems on boot up. Occasionally it won't even POST at first, and I usually just hit reset and it POSTs. Then when I get to the windows loading screen, it usually blue screens, giving me one of a number of different errors. "IRQL_NOT_LESS_OR_EQUAL" is the most common, but I've seen at least 2-3 others that I can't recall. I reset again, and sometimes I'll get a "Windows is loading files" white progress bar at the bottom of the screen, which inevitably puts me back in a blue screen. Eventually after several pass-throughs like this, it'll actually get to the login screen, and from there it's usually fine. It seems that it takes longest when it's really cold - for some reason if I have the PC running for quite a while, then shut it down and do a "cold boot", it boots up just fine (usually).
2. Just recently when I was switching between my monitor and my alternate display (a 47" LCD I use for "armchair gaming"), it lost all of my displays except 1, and refused to display anything but 800x600 or show anything but the default adapter. When I tried to load Nvidia control panel, it told me that it didn't recognize any Nvidia hardware as being present. I've asked my friend to test my video card for me and I'm using an older 8800 GT in the meantime (which it did recognize), but the other problems seem to be the same.
3. It will spontaneously blue screen me and restart on its own with varying frequency. Lately it's been happening a LOT (about every night - I leave my PC on all the time, usually). This is the one that really prompted me to start troubleshooting.
Background info: since I've had these problems I've replaced the hard drive, the power supply, the video card (see above), and even the motherboard (more on this in a minute). I've also run memtest extensively on the RAM and had no issues, and run extensive stress tests (with Prime 95 and others) on my CPU with no issues.
I had similar problems with the first mobo I bought, which was an Asus, but it was the P6T, not the P6T Deluxe V2 I replaced it with. The problems were lessened with the new mobo, so I sort of just ignored it since it really only made for a headache when booting.
I'm starting to suspect the mobo is really the culprit here, but I'd appreciate your advice, as I don't have the experience of much of this community.
Thanks
