I built this home theater pc in october, and didn't start having problems until recently. At first I just thought it was my graphics card failing so I RMAd it. My replacement came and I'm still having the same problem. My computer boots up fine, but as soon as I try to log into windows I get a black screen and my computer restarts after about a minute. (It doesn't always restart... sometimes I can hear the windows login sound, and I have to flip the switch on my PSU to restart my computer.)
I'm able to get into windows sometimes. When I try to watch a video or play a game my graphics drivers keep crashing and the screen goes black. Sometimes the drivers recover right away and I'm able to play the game or resume whatever it was I was doing. Other times the drivers wont recover and the screen will remain black until I alt-F4 out of the game.
I'm able to boot into windows without any issues if I don't have any drivers installed for my graphics card. I also don't have any problem using my computer if I use the onboard video.
I've read that a lot of other people have been having this similar issue and they haven't gotten much help. A couple of them said that as soon as they switched to windows 7 64bit they started experiencing this problem.
From what I'm able to tell it's either my PSU is no longer able to handle my graphics card, my pci express slot is faulty, or my os is causing the problem. I'd really like some more opinions before I mess with anything and potentially break it even more. I'm currently typing this on the computer in safe mode using the graphics card.
Specs:
-Windows 7 ultimate 64-bit
-2x2GB Patriot DDR3 1333 RAM
-Nvidia PNY GT 440 GDDR5 1GB
-Asus m5a78l-m lx motherboard
-Coolmax 600w PSU (I know they aren't a very good brand which is leading me to believe that this is causing the problem.)
-AMD athlon II x3 445 (I had it unlocked to a phenom II x4, but to make sure that wasn't the problem I cleared the cmos and set it back to default.)
If you need any additional information please let me know.
