    About 3 weeks ago I started seeing major screen corruption while playing video games and when booting into vista with the aero desktop. XP actually loaded ok, but again, screen corruption in games. My first suspect was the video card since it is almost 3 years old now.

    Well I went ahead and replaced it with an evga gtx 260. http://www.newegg.com/Product/Product.aspx?Item=N82E16814130434
    Now, a couple weeks after installing that I'm getting some of the same exact screen corruption in games but NOW I'm even getting it in bios when the computer boots. Can't even read the bios setup screen now.

    In addition to that, if I leave the system off for a while I can boot up with only minor screen corruption (gets worse tho). Last time I tried booting up my keyboard wouldn't work (couldn't hit delete to get into bios). Temperatures are shown below, I had just checked them prior to all this happening because I was seeing minor screen flickering. Everything except the MCP (southbridge) was very low temp.

    mobo - evga nforce 680i http://www.newegg.com/Product/Product.aspx?Item=N82E16813188009
    memory - 4gb ddr2 800 gskill http://www.newegg.com/Product/Product.aspx?Item=N82E16820231209
    CPU - 3 ghz core 2 duo
    PSU - 700 watt thermaltake http://www.newegg.com/Product/Product.aspx?Item=N82E16817153039
    drive - patriot torq SSD http://www.newegg.com/Product/Product.aspx?Item=N82E16820220389


    temps - CPU idles at 34, GPU at 44, gpu memory 35. MCP (southbridge) runs at about 57C but it has always run that high ever since I got the board. ambient case temp runs about 27-30.


    Anyways, I'm looking for some advice where to look next. Do you think it could be the motherboard gone bad? Maybe the southbridge? Doesn't that handle the pci-express slots? I seriously doubt it would be another video card gone bad :/ At least I would hope so. Thanks for any advice.

    oh..
    artifacts in bios? time to change your card.
    mobo aint the issue as far as i know. try removing the card and run pc without it. 90% chances are.. you wont get those screen corruptions..!!

    even tho the card is brand spanking new out of the box? I was just having artifacts with my last video card (3 weeks ago) and now I'm getting the same with a brand new one... what are the odds? In addition my keyboard has randomly stopped functioning on my desktop (usb keyboard) yet still works on my laptop.

    like i said, run your pc without the card.
    or plug ur card inside a friend's pc to narrow down the issues.. but mostly, artifacts mean fried card.
    one of my friends had an issue with his motherboard that kept killing whatever pci-e cards he plugged in. he killed some 3 cards. then he realized that it was happening because he messed around with the pci-e frequencies, he used 120 thinking that it will lead to an overclock. i guess it is 100 by default.
    you shd never mess around with pci-e frequencies.. or you'll end up raising a card killer.. =p.
    there are chances that your pci-e bus has some serious errors. have your bios re-flashed.. or upgraded.
