Hi,

I guess I already know the answer but can someone confirm please. The card is 4 months old only bought from EBuyer. I get one long beep and 3 short beeps at post. The fan spins and the two led's light up briefly and then go out. No signal is received at the monitor. Tried several times by swapping different power connections but nothing. Tried with old 7600gt and all working fine. The problem occurred when I'd been on the internet for a couple of hours. The screen simply went blank and that was it.

PS. Anyone know what the serial number looks like and where I can find it (no s/n but there is a RoHS whatever that is).

Sapphire HD4850 512 Dual running on an i7 920 asus P6T-SE, 6gb Ram, 450W Antec. Vista 64. Nothing overclocked and BIOS at default (yes, I'm boring)

Many thanks.
