Does a motherboard's BIOS reset when you remove or install a new cpu, or do I have to manually go back in and reset it myself? The motherboard in question is the Gigabyte EP45-UD3P

Depends on the motherboard. But most of them will detect the new CPU and ask you to enter the bios for changes. If that fails then you can remove the battery or short the CMOS pin on the motherboard.

I'm just asking because I will be selling it and I feel I should reset it to stock settings since I won't be selling it with a cooler.

Well, yeah.. if you are selling it you can default the bios to reset the bios settings. Just short the CMOS pin on the motherboard. Check the motherboard manual.

When installing a new CPU I'd recommend resetting the BIOS anyway. Be be safe, just save (if possible) and take pics of your BIOS before the new CPUs gets installed.

I took the battery out, waited 15 seconds and put it back in. That would work, right?

Yeah, that would reset the CMOS. Also, the time may get out of sync after you do this so make sure your time is synchronized correctly.

ok, so the person I sold the motherboard to is complaining that it keeps locking up on him. Any ideas what could be causing this? He has already tried different RAM

To do a clear CMOS it depend on the motherboard... mine is a f**** bas****... It needs to remove the battery, jump the CMOS clear jumper and unplug the power at least 30sec to 1 min... maybe you could try this, this will assure a complete CMOS reset... after that enter the bios and select load default and save...

I don't know but it only can be helpfull, you can check the temps too maybe the cooler don't sit properly and the computer lock due to overheat... or the voltage are on the overclock value so too much heat for a stock cooler... it's for that i recommend to load "default settings" maybe it has only reset to last known good settings like mine do when i remove batt and power for 15-30 sec... (i have a dual-bios mobo so i really need to clear it with the jumper)

turns out it might have been his SATA cables. I had a similar incident when I made my new build. I switched out the SATA cables and bingo, fixed.
