Omnibook XE3 blank screen randomnly

[adrian]

Hi there,

I have an HP Omnibook XE3-GC and on bootup sometimes it reaches Windows
sometimes only reaches BIOS checkup, and then suddenly the system
freezes and the screen goes blank. Sometimes I even get to work on
windows but the same thing happens after a short period of time.
I have tried reinserting hard disk again as I read somewhere that this
is a a common cause of these kind of problems, but no luck.
I really think that it's a heat problem. If so, how can I fix the
overheating? Has this ocurred to anyone else?
I would be very grateful for any kind of help.

Thanks a lot.

Adrian.
