Hi
I've just bought and installed a Gainward Bliss 8800GT 512MB into a built on an ASRock 4CoreDual-SATA2 motherboard which was previously happily running Vista Home Prem 32-bit with a 7300SE installed, and does the same with an XFX Geforce 7900GTX 512MB
Unfortunately the system just won't boot - not even a POST - and doesn't seem to be outputting a signal to the monitor. The 8800GT does seem to be receiving power - the fan is spinning (quite noisily actually). As I see it, one or more of the following could be wrong:
1. The 8800GT is goosed (and I'll have to RMA or return it)
2. My PSU (a WinPower ATX 500W) isn't up to the job, although I would have expected it to POST - so I'll have to return the 8800GT under the DSR
3. The 8800GT is incompatible with my motherboard (return under DSR)
Any thoughts, anyone?
