I have a Intel duo core 6600 with 2gb ram and a 8800 gtx.
It's a custom system I ordered from cyberpowerpc.com and I had it for 6 months with absolutely zero problems, then one night shortly before I turned it off I noticed a slight flickering of video artifacts on the screen. Very subtle, didn't think much of it. I powered down for the night as I usually do. The next day after the PC had been on awhile I noticed them again, this time a bit worse, but it was the end of the day and I was about to power down anyway. Now the next day the rows of artifacts (little hash marks or bent lines) got worse until eventually the screen froze. Now occasionally when I boot the PC it doesn't even finish booting, there's no video signal. Rebooting will fix it, and sometimes the PC will run fine for quite awhile, maybe hours, but eventually I see the artifacts and it locks up. Other times it happens immediately after boot up. And when I do get the artifacts, the icons and windows on the desktop don't seem to be updating. Sometimes I can move the mouse pointer around but can't click or move anything, then eventually even it freezes.
It's not a heat issue as I've checked the temps of the video card and CPU, and as I said this can happen from a 'cold' bootup after the PC's been off all night, or if it's just sitting idly at the desktop under no stress. All the fans are working properly as well. I also did a full virus scan and nothing detected.
Now I had let the system sit unplugged for literally months without trying to address the problem because it wasn't pressing; I used my other older system. Well last week I finally decided to tackle the problem and I replaced the PS first. I boot up the PC after it had been sitting unplugged for months and everything comes up fine. I leave it on all day and night and no problems, so I thought that maybe that fixed it. The next day, no problems again. Then, oddly enough, I started noticing the problem again and it started subtly just like the first time. First day I saw only slight brief flickering lines. Next day they got worse. Third day the system eventually locked up. Rebooted and within 2 mins I see the artifacts and it locks up again.
What in the world could cause a problem like this and for it to seem to start subtly then progressively get worse? Any help is appreciated.
