I am having an issue with an HP a500n desktop. On start up in the morning, it was booting into windows, showing the desktop, then rebooting. It would do this about 4 times and then start up normally. After that, throughout the day, it was fine rebooting until it was off overnight again.
I ran AVG, spybot, malwarebytes, and combofix. It was running considerably faster, but still hung up on boot in the mornings- just froze, didn't reboot itself.
So, yesterday I wiped the drive and reinstalled Windows from the HP recovery disks. Removed all the bloatware fluff- trialware games, etc- and it ran great. This morning, it froze on start up a couple times before booting, and is giving a Dr. Watson Debugger error.
I'm wondering if it's a bad HDD- should I run a low level to search for bad sectors? I've never encountered an issue like this on initial start up, which after finally booting once, didn't happen again until sitting overnight, off.
Any ideas would be greatly appreciated.
PS- After the reinstall of everything, I tried installing AVG free 8.0 It kept on telling me I was not using a new enough version of Windows- even though XP Home SP 2 was installed- so I just installed Avast.
