After installing new CPU, everything went crap.

I have been putting a lot of effort into trying to find out why my computer has became very unstable after I upgraded from an Intel Core 2 Duo 1.8ghz CPU to a Intel Core 2 Quad q6600 2.4ghz processor. I have made sure that I have the latest BIOS for the mobo. I have updated all of the drivers. I even reinstalled Windows 7 Professional 64-bit (OS). Ever since I put in the new CPU, programs have been crashing, especially games (ex. Fallout 3.) Other programs haven't been installing correctly as well as some other performance issues. The cpu is running at the correct speed. Could anyone tell me what I'm missing? I've been working on this for the last two days and I'm becoming increasingly frustrated.

Specs:
OS: Windows 7 Professional 64-bit
CPU: Intel Core 2 Quad q6600 2.4ghz
Graphics: nVidia GeForce 9500 GT
RAM: 4gb
Mobo: ASUS P5NSLI nVidia chipset.
Hard Drive: 250gb

Did you update your bios before pluged in the new cpu?

Sorry for late response. I updated the BIOS after installing it. If this is a bad idea, I don't have the old cpu to put back in so what are my options? Appreciated.

Try resetting your BIOS options to default.

Then verify that the memory timings and voltage are set correctly as well as the CPU voltage.

To reset to default BIOS I should either remove the mobo battery or switch the CMOS jumpers right?
Here are my voltages according to SpeedFan:

Vcore1: 1.31V
Vcore2: 3.36V
+3.3V: 0.00V
+5V: 5.00V
+12V: 11.90V
-12V: -6.11V
-5V: -3.09V
+5V: 5.08V
Vbat: 3.01V

All the ones I put in bold are bad. Hell a Vcore of 3.36v? Thats way to high. 1.31 for Vcore 1 looks right for a Q6600.

I would check your PSU. If SpeedFan is right about the voltages then your PSU might be bad and not supplying the proper voltage.

I don't see on the ASUS web site that Quad cores are compatible with your board.
Where did you get information that a Q6600 would work on your particular board?

You're probably right about the PSU jimmy, and jit's probably right about the mobo not being quite supportive. However, things only seem to be going bad now when it comes to games, I can run everything else fine (otherwise I wouldn't be able to write this message.) I should update both the PSU and mobo and that should set things straighter. Thanks for all the input I really appreciate it.
