Hi guys

every now and then my computer starts locking up and becoming sluggish, then
after about 5minutes of doing this i get a blue screen up saying

BAD_POOL_HEADER

then some other things saying my computer will be restarted to prevent
damage, i then restart and its fine.

I can even go upto about 5days without this blue screen coming up

any ideas on what it is and how i can fix it?

Thanks
