1. There is an error code on the blue screen u need to note that down
2. Get a program called memtest from
www.memtest86.com
Burn this to a disc and let it run the "long" test. See if it comes up with any errors. Let it run for a couple of hours
3. Next up are the hard disks. Get a program called "Sea tools" from seagate's website. Get the DOS/ Self contained version as your OS is already shoddy. Again let it test both disks
4. Finally if both of these turn out to be okay, we'll need to look at the error code generated and the program that caused it to happen.
The error code i've already told you about
The program you find out by:
Right click MY Computer -> Manage -> Event viewer ->
First check system that applications to see what caused the error (you will see a red "cross")
Please next time rather narrating, right in bullets. and please do not use ".." they are very distracting
