Hello guys,

I have a problem with my PC (built in 2017, specs as attached).

The day before yesterday the monitor suddenly displayed „No signal detected“, and I can’t get it to work again.

I have already tried the following:

- Checked the cables and the monitor, that’s not it. Both work fine.

- Put the graphics card in the second PCI-E slot.

- Replaced the graphics card. Didn’t work with the other one either, and the other one works fine in the computer from which I took it out.

- Cleaned the RAM sticks, tested with only one stick inside, in different slots.

- Took out the CMOS battery and drained any leftover power by holding the power button.

- Took off the CPU cooler and added fresh thermal paste.

What else could it be? I would really very much appreciate every assistance here.

Thank you so much.
