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