My System Won't Boot After Getting 'Critical Process Died ' and

[Laval1998]

In the start i had a ROG Cg8480 from late 2012 , System specs were Intel 3770k , GTX640 , 700w PSU , 1 TB hDD and windows 8. Mobo is Asus P8Z77-M

 

The issues only came after I upgraded my GPU to a MSI GTX 970 4g gaming . Immediately after i had changed the GPU, my computer would always say , Reboot and select proper boot device . I then went to the UEFI Bios and checked the boot priority , everything was ok , it could detect my HDD , but when booted into it , it would still say Reboot and select proper boot device . So then i tried booting into windows boot manager , and it worked. But after a while my system crashed and said Kernal Inpage Data Error, i restarted my system afterwards and everything worked fine , then the next day my computer crashed again and this time said Critcal Process Died and now when i try to reboot my system , i cant even get into my UEFI bios and the screen that is suppose to say 'Reboot and select Proper boot device' instead shows nothing except the blinking line.

 

Thing I have tried

I have tried to enter the UEFI by rebooting my system a few times but it doesnt work 

 

At this point i am really not sure what i can do anymore , so any help guys provide will be greatly appreciated

Plug out the battery on the mobo and put it back while the power is disconnected.

CRITICAL_PROCESS_DIED occurs when a process needed for the operating to run properly, well, dies. Processes are like programs, but multiple processes can be used by a single program- and processes directly interact with your processor, hence their name. The bad thing about this error is that it could be just about anything critical to the operation of your computer: namely, your hard drive, your memory, or, if you’re especially unfortunate, your processor.

try to enter in safe mode
Restart your PC.
Press Shift + F8 before the Windows logo appears.
Click See Advanced Repair Options.
Click Troubleshoot.
Click Advanced Options.
Click Windows Startup Settings.
Click Restart.
You then see a list where you can choose Safe Mode

Once you do get into safe mode, be sure to check all of your drivers for issues. To do that, press Windows Key + X and click Device Manager, and from that menu, get Windows to check all of your devices for updates. If driver updates are available, install them. Be sure to remove any programs you installed when this started, and if, even after this, you encounter the CRITICAL_PROCESS_DIED error, then it’s time for you to do a full operating system re-install.

Select any one option
The first option is a clean installation. You will lose all your data, but this is almost completely guaranteed to fix your problem. Press Windows Key + I, click Change PC Settings, click General, and click Remove Everything and Reinstall Windows.

The second option is a System Refresh. You will not lose your data, but your base operating system will still be re-installed. This is less likely to fix your problem, but may still work. To do this, follow the same instructions up until General — and select Refresh Your PC Without Affecting Your Files.

I hope it helps.


.... and yeah if it won't reboot anymore reset the BIOS and such.
