Automatic Shutdown Issue after Win 10

[irfan32]

I have HP TouchSmart 7320 all in one PC which originally came with Windows 7 Professional 64 Bit.

After upgrade to Win 10 my system automatically shuts without giving any reason. It just says shutting down and it goes off. Occasionally it restarts by itself as well.

All latest windows updates have been installed and device manager shows that all devices are working fine. I tried going back to Win 7 and system worked fine. But after Win 10 update the problem re-occurs.

May I suggest you continue using Windows 7 for awhile.
Also, you may wish to download the full ISO of Windows 10 and install it as a new installation, not as an update. It may be that Windows 10 and not properly register some of your programs you have on Windows 7.

Yes, you can shrink a partition and then install Windows 10 as a dual boot  thing with both Windows 7 and Windows 10 each on their own partition.. That I what I do. Windows 10 will make the dual boot thing automatically.
