My computer reboots with a BAD_POOL_HEADER error

This has been happening for a while now, at first I had no clue what it was. Windows told me it was a "serious error" and then told me there was a bad driver. I doubt it, because if it was, it would've happened a longer time ago. But anyway, I changed the system settings so it'd give me a blue screen of death instead of rebooting automatically and it gives me this.

BAD_POOL_HEADER

*** STOP:0x00000019 (0x00000020, 0x85BAF000, 0x85BAF260, 0x0A4C000)

Can someone please help me out?

 

Google " BAD_POOL_HEADER"

There is a lot of different responses and without more info it is hard to be specific to what it may be with your machine.

 

When does this happen, btw? How frequently?

Any devices hooked up to your computer, like printers and such?

 

It happens VERY frequently and I do have printer and such connected.
