Hi all,
I installed a new HD7850 to my PC today, in place of an old 8800GTX. I started up the computer with the new card in the same PCI-E slot, and it went to the windows splash screen. I logged into my user account, where it went to a blank blue screen. It stayed like that for >5 minutes, and stopped responding to input. I powered it off with the main power button, and restarted it. This time, the monitor stayed at standby. The motherboard diagnostic lights indicated that there was a possible graphics card failure. Removing the new card and putting the 8800GTX back worked fine, so the issue isn't the monitor.
The PSU is rated at 750W, and there were 2 6-pin inputs for the 8800GTX. The 7850 has one 6 pin input, so I used one of these. I don't know if the system is posting as there is no display on the monitor. It works fine with input from a laptop also. I've reseated it, reset with the CMOS battery, reset BIOS to factory.
Any ideas? Does it need to be RMA'd or could it be something else.
