My Rampage V Extreme U/3.1 2011-3 board has been playing up with random black screens, BSOD's and general multiple boot errors including overclock messages even though the system is not overclocked.
It has deteriorated over the period of a month to the point where it will now not boot at all after my trial and error hardware changes.
The CPU stats when I could get into BIOS seemed fine including temperature.
During the period of a month and gradual deterioration, I changed the PSU from a Corsair 850RM to an 850I, changed ram for a new Corsair 2400 single stick, changed GPU , re-seated RAM old and new, re-applied thermal paste to the CPU.
Tried BIOS flash, tried BIOS 2, replaced BIOS 1 with a new BIOS chip with latest firmware from Ebay all to no avail.
On the rare occasions that I get the splash screen, when I hit DEL I get a predominately black screen with a horozontal stripe of green pixels and the hit del key message. Systems hangs.
No drives connected just single stick of RAM, CPU & GPU.
QLED consistently shows B2 and the VGA light on the motherboard is constantly lit red, Cards work fine in other system though so it's not the cards
QLED checks and RAM count seem fine with no errors.
Never displayed QLED 00
Memcount seems fine.
Safe boot yields nothing..
Warranty expired in 2018 so no help from ASUS.
Have ordered a second-hand Gigabyte board to test the CPU
Anybody got any ideas before I'm forced to bin the board ?
