Strange problem my 5970 stopped working on main pc.
Shut off my 3770k returned 2 hrs latter no screen on startup bios post codes Ab states the bios is normal.
Next I put a vga monitor on Intel HD-4000 and I have a screen again.
Removed the 5970 and replaced it with a spare 5870 now cool 2 screens a hd-4000 and a 5870.
Next I take the 5970 card that refused to work in the extreme4 after working normal and stick in 1366 at 4200MHz and it works strange.
Remove the temp 5870 and put back 5970 in the extreme4 3770k again no screen.
Cleared the bios reloaded with 2 different profiles that worked tried a different screen a new DVI_D plug cleaned out the PCI-e slot.
Tried the second PCI-e x8 slot slowed down the boot to give the Plx chip on the card more time to work.
Put the 5970 back in the 1366 which still works with it and put the 5870 in the 3770k.
The PS are pc power cooling 750 in both with less then 8 months on the 3770k.
The original PC 750 PS had a tri 5870 for a while.
What stopping my 5970 from working on the extreme4 after months of up time.
