Question

My Windows 10 HP won't start up.

Mar 27, 2016 6:16AM PDT

I tried to remove all of my personal data from my desktop, but when I tried to restart it (so I could go into troubleshooting), the computer started acting funny. It just shut itself off, then turned back on, and repeated this all night. It doesn't send a signal to the monitor, and doesn't respond to the keyboard or mouse.

Unclear in your post:
- You triedto remove something. But you don't tell if it succeeded and if not, why not.
- And why did you want to go into troubleshooting after removing that data?

Anyway, either you removed too much, or it's some hardware issue.

Things to try:
1. Back to your latest image backup and try again.
2. Back to factory settings from the recovery disks or recovery partition or whatever procedure HP prescribed (you might need a Windows 10 install disk for that, but those are free to download).
3. See if it boot from a Linux disk or stick. If not, that's an indication of a hardware issue.
4. Forget about Windows and install Linux.

I can't do anything with it right now.

I was unsuccessful in my attempts to remove the data, and I wanted to go into troubleshooting to try to reset the desktop from there. My main issue right now is the computer is still in a cycle of turning off and on by itself, which means I can't do anything but shut it completely off, but turning it back on leads to the cycle starting again.

So you didn't remove anything. And now it doesn't go into troubleshooting mode.

Luckily, all 4 things I suggested (except maybe the first) can be done by booting from a DVD or a USB-stick in stead of from Windows on the hard disk. If you can't boot from a bootable DVD or USB-stick it surely is a hardware issue, totally unrelated to trying (and failing) to delete anything.

I would try this but none of the screens show up, and the monitor only tells me 'no input signal' (from the vga and dvi inputs) and 'monitor going to sleep.'

If there isn't even the usual BIOS screen at boot, I'd start with trying another video card.
