Last response: in Graphics & Displays

Ok my vendor just gave me a 9800gtx+....My pc has the config of
intel q6600 2.4ghz processor
4gb crossair dominator in dual channel
600W coolermaster extreme with dual 12v rail support
asus p5q pro motherboard.
Now i have windows 7 64 bit and whenever i open my computer i get green dots on certain parts of my desektop. On playing games such as crysis or crysis warhead the game freezes with th dots comming up in the whole screen and the game freezes. on testing the graphic card elsewhere i found that the card has no problem. There is no heating issue with both th CPU and GPU. thinking that my card is underpowered i lowered all settings in crysis but problem persists. Sometimes i also get green lines on the boot screen as well. iS there something wrong with my registry or is my motherboard causing the problem.

dude how do i know if i have any damaged pin in the 6 pin adapters or is my monitor cable or dvi-i cable causing problem. will it help if i change te psu completely. Just wanna make sure it is no motherboard problem. the dots sometimes gets spread like human allergy u know and sometimes they almost disappear. My cpu, card ram mb is ok so whats the problem. plz help

It sounds like bad memory on the video card. Can you call the vendor and say "give me a new one?"

THis stuff usually happens when you overclock a video card and you have the memory clock to high. Normally you just lower it a bit and you are fine. However, it this is on factory settings that may be the issue. If you can, you can try to lower the memory clock yourself and see if that helps. If it does, you know what the issue is.

my card shows 740 mhz clock speed instead of 738 MHZ as stated in the nvidia website. Also games like dead space and fifa runs fine. the problem is with games like crysis and batman arkham assyum. the vendors replaced my old card and gave his new one xfx 9800gtx+ (ver3.2). is my 6 pins from the smps causing thproblems because of insufficient power supply cause i tested a 9400gt and my pc is fine but the later card does not use the 6 pin connectors. plz help

^ Some games don't hit a video card as hard as others. Batman is HEAVY with Physics and Crysis is a GPU killer. So right there I would expect these two games to generate artifacts if any game would.

Best solution

Download RivaTuner or a similar program and try to lower the RAM clock. If your problems go away, then the card's RAM can't handle whatever speeds they're at (stock, I'd assume), and you should RMA the card stat.

are you sure that my smps is not causing any problem cause my pc just works fine with a 9400gt but it does not use the 6 pin connectors. could this be the problems with my motherboard. also when i perform normal tasks like sufring the net listening to music etc. sometimes the entire display goes off leaving my monitor blank. Could this be a simple problem of faulty mobitor cable......need help plz...will try the card for rma and before that will test the card in one more pc.
