i have a dell xps 630i specs below
http://www.futureshop.ca/catalog/pro...0108125&catid=

when i first started the computer i had to manually shut down because i thought it froze. i think this may be the root of the problems. it was a stupid move. so recently i did a reformat from my windows reinstall disk. but the computers behaves exactly the same. perhaps i did not do a full reformat?

The problem i am having consists of the following:
Blue Screen: i can't exactly remember what it says something like the below.
"...disable bios caching or shadowing if issues continue..."
"...please make sure any new programs have been installed correctly..."
etc etc this blue screen crash happens very randomly. while i am browsing, more rare while i am gaming, sometimes during work. or sometimes just idle.
if it helps i will take a picture of the screen
or provide any logs.
"superfetch has stopped working" almost every time the computer is started
"ready boost has stopped working" though this is very rare
random firefox crashes happens very often
company of heroes runs out of memory after 30-40 minutes of play as with other games.

could all this be that my ram is broken? i have done the Microsoft memory checker and things turned out perfect.

any help would be greatly appreciated. again i am sorry for being very amateur and stupid if there are any details i can provide i will gladly present them. thank you all for creating a great community.
