Need some guidance

#1
Hi there good people.

I have Vista Ultimate 32-bit, just done a complete restore using the hidden partition on my Asus F3Sa laptop after getting loads of problems. I got tired using the event viewer to find the problems out. The thing is when I boot up to the desktop it runs for about 5 minutes before it starts to lock up. If I press the power button the screen fades to black with the cursor still on the screen. I also seem to have a problem that when I get the chance to surf on the net I am forever flushing the dns. Windows update starts t download but crashes. Have sent a note to Asus to see what they say but would prefer to not send it and be without for a week or 2. Your advice would be gratefully recieved. If you need any more info just let me know
