My hp pavilion has trouble starting

to Post in another forum, since this is the virus and security forum. If you decide to do so, you might want to include more information about the system you are using. Perhaps you should try http://reviews.cnet.com/5204-7586-0.html?forumID=68&start=0 or http://reviews.cnet.com/5204-6122-0.html?forumID=44&start=0. Hope you get this problem resolved in a timely and proper manner. I hope the links work if not just go to the forums home page and look for them there.
Good Luck!

& corrupted System Files.
Try 1st your restore to working time & without rebooting try Check Disk Error Correction. Once ordered, it will instruct you to reboot. Hopefully, you sys files corrected will solve problem. Can't do any harm. HOW:

Disk/repair (Check Disk) (like SFC)
Left click on My Computer(open)
Right click on "C" or your OS drive if another letter.
Left click Properties and then click Tools Tab.
Left click on "Error Checking"> Check Now.
Left click to enter check mark in BOTH boxes offered.
Left click on "Start".
Computer will have to reboot to begin repairs.
Just leave alone (you're locked out anyway) 'til process finished.
In regular mode will take about 1 Hour (more/less)
In Safe Mode about 2 hours.
If computer normal after process complete you might want to create a new
restore point and Label it POST ERROR REPAIR.
Hope this gets it for you. This is based on using an onboard copy of sys
files if copy is ok.
If copy is corrupted, it may tell you to insert XP or SP2(if patch applied) disk to get new,
clean copy inserted. Good to have disk at hand. Good Luck!!
