"operating system not found" xp home

by tburg10 / April 26, 2010 9:54 AM PDT

I got this message from a used computer that I got recently. I replaced the battery, and hard drive. It worked find until after I installed several microsoft updates and then just went blank (black screen with "operating system not found". I turned it off and the next day powered it on and it worked fine. After using it for approx. 15 minutes I tried to download an update and it rebooted again and said "operating system not fount". What gives?

You either have

You either have a bad hard drive, malware damage, or a bad motherboard. Middle one's easy enough to test for if things are working. Most hard drive manufacturer's have a testing program on their websites, and if those both come out fine, you probably have a bad IDE or SATA controller on your motherboard. The first two are significantly more likely though.

Ok, so the bios can identify the hard drive. Ergo the hard drive is functioning. How do I check for malware when I can't boot up?

You just got this USED COMPUTER.

Why bother with a possibly damaged OS? Just start as if it was blank, install your OS and carry on.

Repairing Windows is never a sure thing and since this was just acquired, what better time to start fresh.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
