Does the M/board have its own output? if yes try just that.
Second, use windows 7 generic drivers for the cards.
Try one card at a time.
What psu do you have?

Driver sweeper will just make things worse so I'd suggest not using it again. If it's still causing problems after a fresh install of Windows, I'd suggest that it's either a BIOS issue or the card is borked.

Hi
what can i do about the bios issue and I'm sure it is that due to getting a Bios Boot message asking for a bios Flash from Cd Rom Floppy Usb etc at startup.

Thanks for the replys.

The original m/board disk should get you going. My board is an Asus deluxe board which offers eazyflash for bios updating.

Could bad Ram be the problem? i have 3gb ddr3 though win7 says only 2gb one is faulty looks like.

Clear Cmos on the back of your mobo, its a button just under the top usb's like a green circle arrow. try that

Hi Mate thanks for the reply.

I have tried that before still not working.

First time i ever used it was in CF and it worked then after a PC restart no.

Would it work at all if it is faulty from Overclockers?

You did do it correctly didnt you? hmmmm load defaults in the bios. If you cant you can also use the reset button on the mobo. tried both cards by them selves? also do you mean you can boot into windows without the drivers installed? did you try to overclock your cards?

I did do it right.my older card works new one no on there own.I've no problem starting windows with both cards in though only without ATI Drivers installed and then the resolution is poor.

I overclocked my older Card with MSI Burner though since formatted my PC is it still OC.
