Blue screen of death on Vista 64 bit?

ok well keep trying to boot up your computer and if those errors keep appearing, the same exact ones, letter for letter, number for number, it is more than likely that you at least one bad RAM stick. if it's only one that is bad (if u have more than one). open up your computer, powered off and unplugged, and remove one RAM stick and boot the computer, if it works that means the one u removed must be replaced for optimal performance, if it doesn't boot swap the RAM sticks, if that doesn't work than both RAM sticks may be bad. RAM isn't too expensive btw, if u have to buy more, get at least 4 gigs. 2 and 2.
