I've been running a asus gforce 8800 gts 320mb on my desktop, and apparently there was a sudden failure. I'm getting no output from it, but the system seems to have booted up - since i can hear sound from it. Monitor seems fine, but i have no other DVI-D devices to test if its a DVI issue, but VGA input into the monitor works fine.
So, could a video card fail in such a way that it might pass POST tests, and the system could still boot up?
EDIT: should it be relevant, the system runs windows XP professional.Ping and RDP are disabled. I'll also be trying the card on another system later
Tested: different computer using VGA on monitor
Switching DVI ports on the same card
Switching DVI cables - apparently works for a while then goes down again
Not possible to test right at the moment
Trying a different card on the system (but that would solve the problem if it is a mysterious card failure)
SUSPECTS
Overheating - the card worked when switched on after it was shut down.
Cable - ruled out
Connection - switched cables, both cables were secured during testing
Answer
The short answer is yes. The final output stage of the card could fail. POST cannot test this.
