A few days ago I tried overclocking my CPU through the BIOS, which I have done many times before. Although this time, after saving and applying the settings, my PC tried restarting, only this time it would bootloop. Fast forward some reading on what the problem could be, I decided to replace my PSU and installed the new one. The PC wouldn't boot up anyway. Nothing, not even a beep. Today I tried replacing the CMOS battery, but that doesn't fix it, my PC won't respond at all. Do I have to replace my motherboard?

Update your post to include full system hardware specs and OS.

PSUs (old and new): make, model, wattage, age, condition?

Doublecheck all power connections between PSU and motherboard.

Check that the new CMOS battery went into place correctly - both polarity and fully inserted.

Try another new CMOS battery - always a chance that the current "new" battery is faulty.
