[SOLVED] **Desktop PC No Video** - Phantom Issue

[Alexey]

What are parts which were not replaced yet? Chassis and PSU? (I know PSU tested good, but it was not replaced yet)

(I know PSU tested good, but it was not replaced yet)

I still cannot boot even after replacing the motherboard, CPU, PSU, RAM, GPU - everything

Make sure you test it separately with no components that were ever connected to the cursed system. We do not know if it is infectious.

+1 ^^^ This. Great advice as you don't know if one of he other components is faulty.

I was thinking of an old joke of a physical computer virus - an oil-covered floppy disk. Once you insert it into a drive, the drive becomes infected (contaminated with oil). The drive will then infect (contaminate) whatever floppies are put into it. I'm not aware of anyone actually testing this, but I was thinking along these lines.

I'd not use the original power supply. Use one that you know is good and have used many times.

That is actually a very real problem sometimes. Especially when dealing with ID ten T's. Back in the floppy and tape days it was not unusually for the media to get dirty. Those not in the know would just shake/blow it off and then mount it. Inevitably get the call, it's not working. Try another floppy it does not work. Put that in another machine to test..... I've also had it happen a few times with ports like USB and Firewire.

I just had the exact same problem with a Desktop Dell Inspiron everything worked except video you could hear it loading
and if you pressed the power button it would turn off
after about 40 tries the video came on just once and if I restarted it worked every time but when I shut it off
the video never came on again spent many hours as it was not an old desktop
The owner said he unplugged the hard drive while it was on
so I'm pretty sure its a fried M/B

The new motherboard fixed the issue. Had to reset Windows 10, though. Works like a new computer now!
