Hello, My PC was working fine today & all of a sudden I lost GPU signal to Monitor.
The 1st thing I did was use a PSU tester & all the LED lights on the Tester are green EXCEPT the 5 Volt indication. One of my GPU Slots needs that 5 Volts for the Buss that it's on, & I've seen this happen before, so I'm claiming a Bad power supply due to no 5 Volt Rack Power. I've already cleaned my Ram.. I'm aware of what is known as "Chip Creep" due to lots of power ups & downs in the same day,, day after day,, over time.
I didn't clear the CMOS yet.. But I'll try that nest, but I believe it's due to the loss of the 5 Volt Rail on the PSU.
Lost Signal today. PSU is at least 5 years old or more.
