to the forum. Ok firstly you do not need drivers for usb if you use xp they come in the operating system.
secondly the error message will be either a driver problem faulty memory or in worst case senario (not likely cpu)
ok for the first instance enter safe mode and remove usb drivers.
Check your temperatures make sure there not high
Test machine and if it does not crash then it was a driver issue.
If no joy run memtest 86
http://www.memtest86.com/ you will need to burn a cd image and boot from this.If it fails the tests try 1 stick on its own to test each stick of ram.
If it passes this does not mean the ram is good however try with 1 stick at a time and test to see if theres a problem
What ram have you got a full componant list may help
If all ram is tested but still crashes test the cpu prime95 will do this and will tell you straight away if theres a cpu fault
