|Here's my issue:|
I'm running Windows XP Pro SP3 and recently have had an odd lock up issue. Randomly my screen goes haywire and locks up-- the entire screen looks like "dragging remnants" or sort of like if you pasted a 1 px high by 1024 px wide image over and over again. No blue screen, no ability to use the mouse, it's just locked on this screen.
I've tried a few things -- I've run Windows Memory Diagnostic and Memtest to check the RAM, which seems fine. I've defragged, virus scanned, and checked CPU heat-- all normal. I've rolled back the video drivers and reinstalled and hunted online for answers, but still I get the random lockup. Sometimes it's after 10 minutes, sometimes it's after 2 days but usually it's 3-4 times a day. There's no specific program I'm running that makes it happen.
Any idea where to go next would be awesome. I've had a blown MOBO before, but all the capacitors I've seen are good. Since the RAM checked out, I suspect either MOBO, the onboard video card or drivers (in this case an NVIDIA GeForce 6150 with updated drivers) or CPU? I don't want to reinstall windows as I don't think it's a software issue. Of course, I've run chkdsk with both /F and /X parameters to no avail.
Any ideas?! Thanks
