Dead old pc

My old pc went dead and won't reboot. Put in an old seldom used cpu, still no boot. Check the CMOS battery, and it is almost dead at .01 v. Remove cmos battery from another desktop (which measures at less than 1 v). Put it in the old pc, but still no boot. So, what could be my trouble?

The power supply is a Corsair TX750 and is pretty new. So I do not think it is the problem. I'll get a new cmos battery and see it will work. BTW, the cpu is spinning, so does the case fans.

correct me if I am wrong but a mobo will boot without a battery it just won't save any of the bios settings when you power down.

That's different from "no boot", did you try a different GPU? Also, like Phill said, you can try without the CMOS battery before buying a new one. Also a new PSU doesn't mean it's not defective, I would still try another PSU.

Will the memory modules cause no boot? I have 2 sticks, removed one and used one at a time, still no boot. I used to have 3 sticks, but one burned out. Maybe these 2 are burned as well. If they are burnt, will it boot?
