Which one is dead, the CPU or the motherboard?
Hi
I just increased the speed of my PC and then turned it off properly. After that, when I tried to power it back on, it refused. I ran a power supply test and everything checked out—my motherboard was working normally. Now I’m wondering if I can be certain my CPU is damaged because the motherboard seemed fine during testing.
Best regards.
Have you removed the PSU from the case and attempted a jump start to check if the fan turns? If you use the 20+4 pin connector, aligning the clip with the right side and inserting a paperclip into the second and fourth wires on the right side can initiate the PSU. If the fan doesn’t spin, the PSU is probably dead. When it does spin, consider using a multimeter to verify voltages at the connectors. The following links may assist in determining the correct voltage levels: https://www.google.com/search?q=24+pin+p...OQx31YM%3A...
Are you certain your CPU was damaged because the motherboard appeared to be lit up? That doesn't clearly confirm it's dead. Which motherboard are you using? Do you have access to the BIOS settings?
I believe you increased the processor speed in the BIOS settings, if that's the case unplug the machine and remove the small CMOS battery from the motherboard for a few minutes. This will clear the BIOS configurations. Reinsert the battery and attempt to start the computer again. If everything functioned properly without sudden shutdowns, it's unlikely any damage occurred.

I think you increased the BIOS speed, if that's the case unplug the machine and remove the small CMOS battery from the motherboard for a few minutes. This should reset the BIOS configuration. Reinsert the battery and attempt to boot the computer again. If it was functioning properly without shutting down abruptly, it's unlikely you damaged anything.
If your motherboard includes a Clear CMOS jumper, would that be a more suitable fix?
In my Asus M5A99FX PRO R2.0 model, I tried to reverse an unstable overclock by shutting down, unplugging the system, holding the power button for five seconds, and taking out the CMOS battery for thirty minutes. After lunch I returned, reinserted the battery and tried booting. A BIOS screen appeared indicating lost CMOS settings, which were then restored, but the overclock issue persisted. Later I swapped the jumper from "Boot" to "Clear CMOS" and that resolved the problem.
Hi
Have you reset the cmos using the jumper on the motherboard
This would clear any overclocking
This often lets the system restart normally again
How did you overclock the system?
Increasing the voltages can do permanant damage, while intel K and some AMD cpus can be overclocked on suitable motherboards
Give cpu & motherboard and ram details

WeberDarren97 suggests resetting the BIOS by unplugging the computer and removing the CMOS battery for a short time, then reinserting it. He shares personal experiences from his Asus M5A99FX PRO R2.0, where adjusting the jumper helped restore stable performance after an unstable overclock.

I'm unsure how it happened since it usually resets every six half-dozen times. Removing the battery didn't seem to help. Still, it worked—though it erased many settings and somehow fixed the overclock.
We don't have enough evidence to confirm the CPU is completely damaged. What motherboard are you using? Can you access the BIOS settings? I own an MSI h55m-e33, but I'm unable to enter BIOS and it doesn't respond. My PSU is functioning correctly when turned on.
