Computer Problem - No BIOS after clearing CMOS

[Marcem]

I got a new processor today, and after installing it, I tried booting up, but it just stopped at verifying DMI pool data, and my PSU was blowing its fan at full blast.  So, I tried clearing CMOS to see if that may fix it.  I removed my mobo's battery and put it back in a little while later.  Now when I try booting, it starts for a second, then resets, then nothing happens after the fans spin up, with my PSU still doing the same thing.  Did I fry yet another mobo?

Thermal Paste?

It was already on the cooler that came with the cpu.

Did you upgrade from a single-core processor to a dual-core? If so, how old was your motherboard? It may not be able to support the processor.

I ended up killing a motherboard that already had an unstable BIOS by replacing the Pentium 4 with a Core 2 Duo.

Can we get specifics on your motherboard, processor and power supply?

I have had something like this happen to me a few times. In my experience, it would be 1 of two things.
1. Bad CPU
2. Bad or not powerful enough power supply. <-- This seems more likely in your case.

My PSU fan thing ended up being my issue, I accidentally hit the high power fan switch.  @Miga: Yeah, I'm upgrading to quad core from single.  My mobo's box says it's compatible. It's a Gigabyte EP45-UD3L.

Also, my CPU is an Intel Core 2 Duo Q8200, and my psu is a rosewill Power series rp550V2-d-sl

waitwhat
I'm confused, you said you're updating from a single-core, but a Core 2 Duo is a dual-core...

[Marcem]

Upgrading TO.  Also, I mean Core 2 Quad.  I'm still having the issue, but the PSU thing is fixed.

Problem: No such thing as a Core 2 Duo Q8200, do you mean E8200? Or do you mean Core 2 Quad Q8200?
Nevermind.

Also, what graphics do you have?

[Marcem]

nVidia 8500.  I don't hear POST, though.

I really don't know with your computer, but I'd say the problem could lie with your cpu.

[Miga]

Did you try putting the old CPU back in?

No, but I don't think that that would work.  It used to show POST with this CPU in.
