While I was playing Left 4 Dead for about no more than 30 mins I get this http://img5.imageshack.us/my.php?image=74872231.jpg Is this a video card problem? HDD, Memory, Monitor, Overclock? I even exited the game and the random moving pixels remained there all over my screen.
Hmmm looks like trouble... Looks like a timing problem... When the computer boots, you have the same messed up screen? Is the video cable still GOOD connected? If the above quetsions are YES and YES then. First stop the overclocking, always the first step. Then see what happens, everything ok? Step by step OC again.
Id suggest you check your video card temps, most gfx artifacts often start due to overheating of the card. If you overclocked it, reduce your clock. What gfx card are you using?
Yep, CPU or GFX overheat. I had the same when I left my fan manually on idle speed and launched crysis, about 10 minutes in it did that - I went back after it recovered and the card was about 95 degrees I say "or CPU" because I'm pretty sure that can do the same thing, give a big green screen. Or a black screen with a series of green lines across it, I seem to remember getting that one on my pentium D.
That looks like graphics card ram to me. Had a similar problem (although far less pronounced) with my first 7900GT back in the day.
Definately your graphics card, it's either overheating through an overzealous overclock or the heatsink isn't sat properly. If you have overclocked it, reduce it to factory, if that doesn't sort it out then whip it out and make sure the heatsink is sat firmly square. Worst case scenario is the ram on the graphics card being cooked, if thats the case it's rma time
Thinking about it, I'd be really surprised if it's a major problem with an HIS 4870x2 (I'm an HIS loyalist, never had a problem with one). Have you tried revving the fan up a bit in Catalyst Control Center?
When I hoovered a bit off my old 6800GT the screen looked like that, if it keeps doing it it's broke.
yeah i've had that on SLI before and it turned out i blew out my GPU... i kept it to take a closer look later, and when i finally got around to it i noticed it some of the transistors were literally blown out... as in they got hot and blew open... thankfully i had my second card still in order and my computer runs fine just no SLI id take a close look (physically) at your GPU and make sure everything looks normal
It could be a heating problem, the xbox360 shows a similar image when it over heats. That or you have used the over clocking facility program that comes with your graphics card, which has resulted in the settings being incompatible.
To repeat some of the questions... * how is it after a reboot? * how is it in BIOS? * what are the temps on your GPU? This thread suffers from bad info. Maybe a topic title that actually describes what's going on? The PCIe freq may or may not cause it. It's usually harmless, it just ups the bandwidth of the PCIe bus a bit, but nobody ever fills it anyway
