I need some help figuring out a strange problem. My display will occasionally disappear; it stays powered on but appears as if the computer is off (no connection). The computer is obviously still on, I just can't get a picture.
My video card is an nvidia geforce 7950 GT and it's worked fine for the past year and a half.
Not sure if this is related, but I've recently had problems with my onboard nic. My mother board is an msi 975X. I would boot up and my networking card would be disabled by default, and sometimes just crap out. Restarting would sometimes reenable it. Not a big deal. However, once I disabled it permanently and installed a pci nic, my display problems were fixed... for about 2 weeks.
I can sometimes get my display to come up by powering off and switching which dvi port I'm connecting to (there are 2 on my card). Once, I switched it to no avail, so switched back and my display came back up. Weird...
Any thoughts? Is my video card or motherboard going bad? Is there a way to test it? (FYI--everything in my computer is the same age; about a year and a half)
