Myke thanks for your reply,
No I dont get a BSOD it just freezes soon after loading the desktop with the `hour glass` suspended, and stops responding.
I took it to a shop for them to have a look but they reinstalled windows ( charged me of course) and returned the laptop with exactly the same problem. I will ask them if it was full format.
I can use Safe Mode with networking, I have run chkdsk and initially it too would get stuck, but after the reinstall I was able to complete chkdsk.
What other diagnosrtics do you suggest? No there are no strange noises, except that it was heating up a lot. i cleaned the grill in front of the fan and it seems to be running ok now.
Is the prob with the flux capacitor a hardware fault? can it be fixed?
Thank you
Farid
