Okay, becuase the GTX 560 Ti is currently out of stock, I've been trying to use this XFX HD4890 XXX as a temporary solution. However, the card won't boot. W/hen I put in my HD4890, there was no video feed, and bios beeped 4 times, I uplugged the HD4890, and put in a GT220, which requires no PCI-E power cables from the GPU. The PC booted fine. Afaik there's two possibilities; the PSU doesn't supply enough power, or the HD4890 is bad. Anyone have an idea?
Yes, I seated the card, reseated the card, re-connected the PCI-E connectors. When I took off onboard graphics from the BIOS and used the card, the case speaker made four beeps; one long followed by three short. When I searched this, it came up as something like "bad video memory or no video card present". I suppose this means it's more likely that the card is broken?
Mm, I can't find any 7870's in the UK for a similar pricepoint to the GTX 560 Ti's, the cheapest I could find doing a very brief search before going out was a 7870 @ £190, and the GTX 560 Ti I had my eye on was @ £167.
