I'm having trouble diagnosing this problem here. The computer is able to boot up when I press the power button, and the cpu fan starts to spin, but there is no video output. I also don't think that it's even getting to BIOS because after I start the machine with the power button, the power button cannot shut it down, even long-holding it, requiring me to flip the PSU switch. There is also NO Post Beeps when removing RAM.
There used to be video though, but when there was it could never make it far into the boot process, as it resets over and over in a bootloop. And the bootloop isn't Windows related, I know that much.
So what do you guys think the problem is here? I've tried:
- switching out the RAM
- trying another PSU (still bootloops)
- testing the output of the PSU (all voltages checked out okay, though 5v = 5.25v?)
- replace CMOS battery
