HELP PLEASE - screen goes manic??

bioshockeruk · 4 Jul 2013 at 00:31

My older computer that I use for the office computer has started to randomly go from normal to garbled screen. The only way to describe it is that its a fuzzy wash of colours like the gfx has frozen. However, this can happen when just idle or when browsing the web etc. The computer parts are only 4 months old as they all got replaced during some random crashing so I completely rebuilt it, but I'm unsure what is causing this new problem.

Could it be a PSU problem, or could it be the GFX card is faulty? or maybe the RAM?

BTW, the comp is on 24hrs as it is running 2 till systems as a server.

If anyone can help me troubleshoot this it would be great as I cannot find anything in the error reporting of windows 7. The only resolutions is to restart the machine via the reset button.

The motherboard has onboard graphics, try removing the 6670 GPU and run off the motherboard one and see how you get on.

Link to your motherboard and any drivers you might need:

If it happens after a while it could be heat related, so check that the fans are all working and that dust isn't coating the blades making them less effective.

Make sure the HDMI, DVI or vga cable you are using works, It may be not plugged it all the way or does not work as it should. There would be nothing of this in the error report so my first bet would be on this ! Hope this works and good luck J

Yeah, check the cable, especially HDMI. Wiggle it around to repro the symptoms.

Thanks guys, i've ripped the fan out and cleaned it and applied new paste, and also replaced the hdmi cable with the one from the sky box! My next step will be to check all drivers as stated, and we'll see if this happens again!

If it still does not work you could revert back to a previous driver

. If think it is the drivers ! Im sure with the new hdmi it will work !. Also might be worth checking if the mobo is in the right place sometimes if you have not put all the screws in the port pannel can keep the hdmi from going in 100% good luck and let us know !
