Thanks for the advice monkey, but i need to be sure that the graphics card is the thing thats knackered as its a £350 card. Is there any ways of which you can check as to whether it is just the card or am i going to have to get a new p.c?

Thanks

You can Try the Video Card Stability Test

If you can hear Skype and MSN starting up then I think you can rule out CPU. Your problems do sound like Video card.. since you have no Video! You have tried using a different screen?

I tried the stability test and benchmarked at 1545fps, im not sure what this tells me,

Thanks

The problems i have are very strange, i can switch my comp on and i will get nothing on the screen, i will switch off and on and it will power up normally asking me if i would like to load windows in safe mode.

Then gaming for instance i will switch COD4 on and it will run terribly with massive slowdown and noise feedback, so i will switch the comp off and on and power up COD4 and it runs almost perfectly.

Although even when its running smooth on singleplayer if i move over to multiplayer its really bad slowdown, absolutely unplayable.

I have two screens and they both work the same so thats not an issue

Thanks

Might wan't to try that stability test when your actually expereiencing the problem.

One thing I would make sure of though, is that the slot next to the PCI-E slot is not being use. If there is a card in that slot, try moving it to a slot further away from the graphics card.

If you have received any error messages at any time, blue screens of death, or anything like that, it's important to let us know, as this will help us to identify your problem for certain.

I can't think of what else could cause those symptoms to be honest pop, and the only way you really going to know for sure is by testing another VGA card in that slot, either from another PC (poss a friends), or some shops will let you return the card after. There is no way that *you* would be able to test that card at a hardware level. If the card is damaged due to overheating/overclocking, it will exibit all kinds of weird and wonderful symptoms, from no video output, to cutting out and restarting, to poor performance.
