had you gone to windows updates and got the multitude of updates you would need after using recovery material to re install windows? If not that is probably what happened it started trying to download and install all those many updates and it locked it up. You may have even needed service pack 2 and 3 with a unit that old. plus of course all your antivirus programs etc would be trying to update also. It is always best when doing that kind of recovery where you will be very very far behind in windows updates to turn off automatic updates and go manually to windows update and first get your service packs in order and be absolutely sure to reboot the computer after each service pack, then get any remaining updates. I usually suggest getting them in small batches and creating a restore point before each service pack and before each batch of updates. Should something go wrong you have a good restore point to return to.

Well, you guys aren't gonna believe this, cause I didn't. I figured out the problem - an iPod! What does an iPod have to do with anything? My mother-in-law has an iPod and she uses a little charger that plugs into a USB port on the front of my PC. Yesterday, while the PC was running, she came and plugged the iPod in - no problem. But, when I attempted to boot up - problem. On a whim, I decided to unplug the iPod and see what happened, because that was the only difference between yesterday and today. Sure enough, with the iPod unplugged, the PC booted just fine. Plugged it back in and the PC won't finish the boot process. Anyone else ever heard of this before?

Not really, haven't seen any symptoms like that listed anywhere! This is a very strange problem, there are lots of people having this problem even before upgrading to Windows 10 (even back as far as Windows XP). I think that it happening after you installed Windows 10 was just a coincidence. My Touch Screen on my Acer Tablet stopped working shortly after installing Windows 10. Ended up being a Loose Flat Flex Cable inside the Tablet, not Windows 10, but my first thought was Windows 10 had caused it! I'll keep looking to see if I can find anything else. Most of what I'm finding are taking me down the same path, Monitor (Display) Settings. Guess I'll steer away for going down that path for now. I do have one other thought: Maybe your Power Supply is going bad and it's not producing enough power to run the computer and the monitor both! Only real way to check this is to replace the Power Supply with a New one. There are ways to check them (if you're an electrician and have the equipment and knowhow)! I don't think it's the Hardware inside the Laptop or the Monitor wouldn't work on Battery Power! BTW, you can pick up new power supplies on Ebay at not too many $$$$.

I know there are differences between machines, even the same models. 8 yeas ago my daughter bought the Samsung VRT set. When my Maytag Neptune bit the dust, a few months later I went out and bought the very same set as my daughter. Her machine's water level was HIGH, very high, up over the boot and up the glass a little. Mine, very little water, very little....until I took the top off and adjusted the water level.
