I started to see probs happening then, as soon as fan started to whirl up really fast, the laptop just shut off, at times it just shuts off itself as soon as it was powered on... I have to put it to use again like "today"... so powered it on yesterday, everything went well, updated Zone Alarm, Acrobat and it may have updated some XP files, but don't know which... after having to restart it... it picked up the same prob as before, it shuts off when the fan whirls up... and haven't been able to bring it back to life since yesterday... read that in some cases I would need to reset the CMOS, for which I followed instructions to remove the battery for ten minutes or so, reinserted and restart it... after that it just won't go beyond the "loading personal settings" window and it either stays there forever, or it shuts off a real long while after once the fan revs up!... have tried in Safe Mode with no results... there's only one user with admin privileges and the guest account... neither opens in regular mode... and in safe mode appears the user and the administrator, but when logging in trying to use the admin user, it says the password is wrong... won't have at hand a Windows CD until Tuesday, but really need to try any other fix ASAP... I'm pretty fam with computers, but this is bugging the heck outta me!... PLEASE HELP since I need to return the laptop I'm now writing with ASAP too!
