The PC cannot start after the thermal paste was changed.
Hello. I changed my thermal paste and cleaned the PC following all the steps, then reassembled it. The PC doesn't boot into BIOS and all fans work properly—GPU, CPU case fans, PSU—but there are no beeps. I rechecked all cables, CPU, RAM, GPU, and even the CMOS, but nothing worked. What might have happened? 😔
When working with a modular PSU, did you disconnect the power cables at the PSU port or from the motherboard, GPU, and SATA drives? Some cables may fit into the incorrect sockets on the PSU, which could lead to serious issues. You should have made adjustments during reassembly. Please verify again thoroughly.
