I recently faced some issues when my power supply unit (PSU) failed overnight. After getting it replaced by a technician, my computer started running again, but I've noticed the CPU temperatures are concerningly high, peaking at around 100 degrees Celsius even under light load. The technician applied new thermal paste, but the problem persists. Here's where it gets odd: if I start the computer normally without accessing the BIOS, the CPU temperature skyrockets to 70-80 degrees and throttles. However, if I hit 'del' to access the BIOS without changing anything, the temperatures drop to a normal 20-30 degrees Celsius at idle and max out around 50 degrees under full load. It's been working fine for a few hours after this, but when I leave the computer off for a while, the high temps return. Any ideas on what's happening?

Make sure to check that both the cooler pump and the fans are connected and running correctly. You should feel liquid moving through the tubes. Depending on your setup, the pump might need a SATA power connection instead of being powered through the motherboard. Also, check the BIOS settings to ensure the pump is detected and set to operate at max speed.
It sounds like your liquid cooler might not be functioning properly. The pump could be having trouble starting, which could explain why accessing the BIOS helps it kick on. If it keeps acting up, you might want to think about switching to a reliable air cooler instead.
