Was running Radeon HD 6870, while playing Bioshock Infinite screen went whitish blue with no warning, computer unresponsive.
On reboot, there was no post. Removed card and booted with onboard graphics. Was planning on upgrading GFX card and motherboard anyway, so bought Radeon 7970 & Asus P8Z77-V motherboard.
After installing new card and motherboard the card problem is still present. No post with graphics card, onboard graphics working.
Card fans and logo light are working.
Setting the grphics device in BIOS to PCI does not work, nor does setting it to auto detect. disabling the onboard graphics does not fix the problem.
There is no signal with either DVI or HDMI cables.
Could it be the PSU? Edit: Have just swapped in a Corsair GS700W PSU and still the same issue
