Screen looks as though it has loads of barcodes across it (purple on white background, green on black background). Before I go ahead and get a new graphics card i just want to confirm it is a card problem and not something else. Did ask previously for decent cards for £80 or so. got a couple of replies, for which thanks. For gamaing I play COD2, Half Life 2 and amgetting Medal Of honour Airborne Assault when it comes out. Any other suggestions for decent cards for that price? Current PSU is 350 watts. Assuming it is a graphic card problem.
when upgrading to a new psu make sure the 12 volt rails are giving enough power to run a seperate power using video card. i would also advise investing more than the link as they will not give the peak power required over a long period of time. i have tried them and found this to my cost.
A couple of times it has looked ok when browsing, although there are still lines on the desktop, then it has gone back again after about 10 minutes. Someone said it might be that the graphics card is overheating. The monitor ( Samsung 205BW) is only about 6 weeks old so I hope it isn't that!
i would think it is the card. unless you have done any overclocking the heat levels should be fine. the card is corrupting the image it puts on the screen. this happened to me with my old 6600gt a couple of months ago. be careful what you replace it with and if you are not sure about anything post back. if you wish post back your motherboard, chip, ram specs and whether your graphics card slot is pci-e or agp
