Hi, When you say it shuts down, does it try to reboot again or does it just shut down without trying to reboot? Also, can you get into bios? What operating software is it? xp...vista...? Hank
What operating system are you using? If XP, see this link for intructions on starting the computer in safe mode (choose safe mode with networking) http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/boot_failsafe.mspx?mfr=true Once in safe mode, scan and clean your computer using MalwareBytes AntiMalware, download it here: http://download.cnet.com/Malwarebytes-Anti-Malware/3000-8022_4-10804572.html?part=dl-10804572&subj=dl&tag=button Why would you be attemptin to install Norton 2008? The 2008 version slows down your computer quite a bit, I'd recommend getting the 2009 version which has been re-writen from scratch and does not slow down your PC.
Hi, What o.s are you using, and can you open windows in safe mode?
