Alright, here is what has happened. I used to have a Pentium D 3.4 GHz CPU, then I upgraded to a Quad Core Q6600 CPU 2.4 GHz (I overclocked to 3.0 GHz by changing FSB from 266 to 333). The stepping of the processor is G0. The memory is PC6400. The computer runs pretty fine until now, I was copying a file, I was trying to run this one audio program, basically I was multitasking and then all of a sudden, my computer crashed and restarted and when it rebooted, it gave me this error message:

Problem caused by Device Driver

You received this message because a device driver installed on your computer caused the Windows operating system to stop unexpectedly. This type of error is referred to as a "stop error." A stop error requires you to restart your computer.

Return the clocking to normal, might be a good first troubleshooting step.

"Return the clocking to normal, might be a good first troubleshooting step"

I agree.

"The memory is PC6400"

Here's a tip unrelated to your problem...configure your RAM to run at 266MHz (DDR533) to match the CPU. And if you overclock again to 333MHz, make sure the RAM is clocked at 333MHz (DDR667).

When overclocking, did you lock the PCI-e at 100MHz? Did you disable any/all Spread Spectrum settings? Did you test the overclock settings for stability by running Prime95 or Stress Prime 2004?

Alright, I went into my BIOS, changed it to the default, then went back into the BIOS, changed from 266 to 333 and from there, disabled Speed Spectrum, locked the PCI-e to 100 FSB and set the memory level to DDR667. Now, does my memory still run at PC6400 Speed? What bad does it do if I disable the Speed Spectrum?
