Help! Did I just kill my PC?

[Saint.Million]

I don't really know anything about overclocking, but I have an old I5-9600k and I previously overclocked it just by changing one of the voltage settings in the BIOS and it ran great for years.

Today I installed a new gfx card and got a message about things being reset to default. So I went into the BIOS to re-enable the overclock but I forgot which setting it was and I think I changed the wrong thing...

I changed one of the CPU settings to 250, which seemed like it would give me an over clock, but now when I turn my PC on I get no display at all.

Is there anything I can do?

Reset CMOS jumper and see if that brings it back

Thak you, but how do I do that?

Sorry for being a noob, but I don't even know what a CMOS jumper is.

Could be a little switch on motherboard backplate, or one on the motherboard, or typically you place a jumper on the cmos terminal for a half second , or remove battery

Yeh just pull the battery out when the machine is unplugged from the mains, and refit the battery after a min or 2.
That will reset your bios to factory.

For future reference you can check your motherboard manual and find where the clear cmos jumper is (usually labelled CLR_CMOS) to do the same thing, as it's often easier to access in a fully built system.

I'm late to the party but given the likely age of the battery it's probably worth replacing it to prevent future issues.
