Posted January 17 (edited) · Original PosterOP Hey, so the other day I cleaned up my PC. With that, I decided to replace the thermo-paste on the CPU and the GPU (GPU first time since 2015 - CPU 4th reapply since 2015). I decided to use liquid with alcohol (certain cleaning cologne) that dries up and evoporates like instantly, wich I always used to clean the old thermo-paste on the CPU. Now this clean-up, for the first time I cleaned up the thermo-paste and the board of the GPU. I might have overdone it with the GPU board resulting in short circuit. But the fan of the GPU spins so I'm assuming it works. Putting everything back together, the PC didn't boot up. Like it kept rebooting and crashing about 2 seconds after each boot. After Googling and Youtube Videos, I tryed playing with the RAMs and their slots. I played with the small battery, the power button getting the MOBO completely without circuit. HDMI-cable & monitor are in working condition and have been tested. Result is, now the PC follows this trajectory: Boot > Crashes in 2 seconds > Reboot > Fans run, keyboard & mouse have power but no display. So I have been googling and used youtube but with no result. I mean I'm at the point of rebuilding a new pc, but it needs to wait.
