son's rig has developed a problem, specs:
Asus M4A77T, latest BIOS
Phenom II X4 850
2x4GB Kingston Hyper-X red DDR3 1600MHz/1.65V
660GTX
Corsair CX600
Philips 24in FullHD, HDMI
Neovo F-419 DVI
Win 7 64bit
CnQ set to auto.
Problem, random intermittent flashing black screen(less than 1sec) in HDMI display. Does this even while in BIOS.
Simultaneous DVI Display works OK (dual screen set up).
Changed: PSU, gfx card, upped vdimm(1.65V), clear CMOS, different dual channel slots, tested another HDMI display(same model).
Fault remains, without change.
Leads me to think the motherboard is faulty, or the EPU feature that can not be disabled, somehow messes up the system.
The board is about one year old.
Do you have some suggestion how I can troubleshoot this further, do not have a spare board to test with.
Was thinking of trying to disable all energy related stuff in BIOS, but need a method to walk through.
Have also a spare set of generic to 1333MHz RAM to test with, but seems far fetched, no?
