I recently just purchased a MSI Frozr III 7950 (3GB) as a re-furb model from overclockers.co.uk. Currently the card will power on (fans spinning) but will not display video and it cannot be detected by the device manager. This card has already been RMA'd and it came back with no errors so it is clearly something else.
My current set-up is:
Motherboard - Asus M4A89GTD PRO/USB3
CPU: AMD phenom II 955
RAM - 8gb (4x 2gb) Patriot G-skill (1333MHz)
Graphics card - sapphire HD 4850 (this is what the 7950 will replace)
PSU - Gigabyte ODIN GT 550w. (w/ 2x 6 pin connectors)
HD - 1x SSD and 1x HD
The original set-up is working 100% ok and has never experienced any problems.
Things I have already attempted:
1/ Updating system BIOS to most current version.
2/ trying 7950 in both PCI-E slots.
3/ uninstalling all current ATI catalyst drivers and installing all drivers required for the 7950 (Catalyst 14.4)
4/ using the 4850, I tested both PCI-E 6 pin connectors as one may not have been providing power, both are ok.
5/ changing Graphics priority in the BIOS from IGP to GFX0.
6/ changing graphics priority in the BIOS from IGP to PCI.
7/ Trying both video outputs on the 7950 (HDMI and DVI).
8/ Resetting the motherboard's CMOS.
9/ Switching the 7950's BIOS to its secondary BIOS.
10/ RMAing the card (As i said before, it came back with no errors).
I originally suspected it might be an issue with the PSU, as it is a bit old, but it is showing non of the classic symptoms of underpowering such as random crashes or BSOD's even when under stress.
CPUID hardware monitor shows all voltages as within limits even while playing games at max settings on the 4850.
I'm literally at my wits end. I have attempted all the solutions I have read online and nothing has worked thus far. Is there anything I am missing??
Thanks,
