Issues booting the PC and shutting it down.

Hello TenForums members!

I'm having some issues with my PC I have never had before. The computer is a personal rig I have personally worked on, but these last weeks some problems started appearing.

Problem 1) {Had this problem for months, I think this problem also escalated to create problem 2}
I cannot "restart" my computer. Do I want to restart? I would have to shutdown and then start it up again.
When I press restart, it starts logging off, shutting down, and when my screen go blank (no signal, pc lights/fans = on) it just stays there for ever. Tried waiting once but after 4 hours I gave up.

Problem 2) {This problem arose since last week)
When I start my computer I get my BIOS screen. After the BIOS timer, the boot screen gets taken over by Windows 10 with it's loading circle.

My computer stays loading here for about 8-10 minutes and then it continues booting like normal.

I am willing to follow many steps to find out this problem!! I suspect maybe unfinished installations or my other HDD interfering with the initial boot?

Also, could this problem be caused by a PSU failing? (My oldest pc component)
My windows is now on my main ssd (samsung evo 500gb) - I also have a ocz 250gb and western hdd 1tb which I had windows on previously (user files still on, no boot)

Hey guys,

I couldn't help my self and tried something on my mind. Opened event viewer and saw 1 particular error spamming over n over.
An error was detected on device \Device\Harddisk1\DR1 during a paging operation

It was my OCZ Octane, i went into bios, rearranged my new ssd to be first and windows boot manager to be 2nd, and now I had an option to choose one of my older installations, something I couldnt untill now. Some progress was made, 4 attempts later I got into windows and problem 2 is now fixed.

I still have problem 1)!!
