Hello.

This morning I tried to turn on my pc, but the screen was fully black. Noticed that all the fans were working (including gpu and cpu fans), but my monitor would show ''no signal'' and my keyboard/mouse would'nt work either. No weird noises or anything different. What could be the problem?

Things I tried:
  • Checked monitor. (Perfectly fine)
  • Reseated my RAM. (Have 2 RAM sticks, tried both in different slots, tried each one individually aswell)
  • Installed my old GPU. (msi gtx 960)
  • Checked all my connections.
  • Bought new CMOS <battery> and replaced it.
  • Removed side fan. (Read online that it could fix the issue somehow)
Specs:
MSI GTX970 GPU
AMD FX8300 CPU
FSP 500W PSU
8GB DD3 RAM
msi 970A-G43 MOBO

Rig worked fine for the last ~5 years until today.

Would really appreciate any help. Thanks.
