Major Computer Issues

[AlwaysWinter]

Hi,

I apologize if I sound angry but I am a very, very pissed off person. I don't understand what's wrong with my pc. Last night, it was working perfect, no issues. Following morning, it all changed.

-The only way for me to access my desktop is by restarting the pc and holding SHIFT + F11
-The screen spazzes like crazy at random times and it stops when I start typing
-I literally ran every single test from CMD like sfc /scannow and a few more. It says that my system is healthy. All my harddrives are healthy.
-My windows 10 blue color (start up) is now PURPLE when I come back to my desktop but when I get to REPAIR OPTIONS, the screen is back to blue again. This is very, very strange.
-The PC loops into REPAIR OPTIONS over and over and the only way to get to my desktop is by holding SHIFT + F11 when I am restarting
-When I put my PC to sleep, it doesn't wake up so I need to force power it off by pressing the power button
-In REPAIR OPTIONS, when I go to repair windows, it says my password is "incorrect" even though it is CORRECT. I ran a test. When I held shift+F11 to get back into my desktop, I used the password instead of the 4 key pin and it WORKED. It's not me, it's WINDOWS 10 that is the issue.
-My pc has had a stuttering a problem since the day I bought it and never has been an issue until LAST NIGHT when I began playing Monster Hunter World again. And now, even when I watch YouTube videos, there is a bit of stuttering/lagging.

Seriously, all I want to do is log into Steam and play video games with my friends. I am struggling really hard right now. I need an answer so I can repair this system. I am FRUSTRATED, because I've literally done everything and nothing works.Windows  even denied me to fix the boot issue when I attempted to repair it in CMD. The worse part is being forced to use shift + F11 to get into my system.

I've never heard or seen this kind of issues, so I can only speculate or tell you what I'd do if I'm running into the same problems.

It seems there could be a display issues, so I'd borrow or get a spare monitor to test, to eliminate the possibility that it's not monitor issue. Second, I'd try taking out CMOS battery, reset and reinstall factory fresh. If neither worked, call HP if it's under support/warranty.

according to this thread ..
have you made any changes ??
when you say restart with shift and f11 what exactly are you going through, just a restart or something?
I ask, because with the HP f11 (simple) computer on restart, you can access the repair / recovery options or other tools ..
but so far never heard of the button in addition !!
