The computer is overheating and won't start anymore.
Hello, I was playing some games on my computer. It shut down because it overheated (I’m 97% sure). This has happened before, but usually I can just restart it without issues. This time it won’t start. I opened the case and cleaned the fans, but noticed the CPU cooler was completely blocked with dust. I cleaned the fan thoroughly and put everything back in place, yet nothing worked. I checked if the power supply was functioning and it was fine. Sometimes when I press the start button, the CPU fan briefly activates for about 0.001 seconds and a blue LED flashes on the motherboard. I’m not very experienced with this stuff, so I’d really appreciate a simple explanation. If you can advise me on what to replace or how to fix it, I would be very grateful.
Take off the cooler, wipe it down, put on fresh paste again, and test with a different RAM module. If that doesn’t work, check your motherboard’s guide for what the blue LED means.
if the power is good, the LED should remain steady and not blink, otherwise it might indicate a power problem. the cx power supply isn't suitable for a gaming pc. if your CPU overheats, turn off the power and reset the CMOS. many CPUs and motherboards have overheat protection; sometimes resetting the CMOS is necessary to restore normal operation.
Hello, stavrosmast, your friends are right—it wouldn't be the RAM if a PC starts without one (their words). Can you clarify why it might be the RAM? Also, I've noticed that twisting and turning my ATX 20-pin cable triggers the same response as turning off the PSU and pressing start. Could it be a loose connection?
