Windows keeps crashing

[Stormzicecream]

Firstly, excuse me for my English.

So I have had this computer for almost 2 years now, and recently I had a kernel data inpage error which seems to have been fixed. I resetted my computer and did some more fixes. But now, if I start my computer, it'll work fine for about 15 minutes and then all the programs will stop responding and windows stops responding. Everything is frozen except my pointer. Sometimes it gives a BSoD with a stop error and sometimes it does nothing and then I have to force it to turn off.

My PC specs:
Alienware m14xR2 running Windows 7
Intel Core i7
NVidia GeForce
500MB HDD
6 GB Ram

Can anyone help me please?

Here are a couple things I would try first:

- Chkdsk: go to start > Computer, right click your hard drive and go to properties. On the Tools tab, under Error-Checking click "Check now..." and follow the instructions to run chkdsk

- Memtest - http://www.memtest86.com/

I have done that and it just finished, didn't work. I will now try memtest.
