Hi. . .
"Critical Process Died" - the closest bugcheck that I know of would be
0xf4 = CRITICAL_OBJECT_TERMINATION
A 0xf4 BSOD indicates that a process or thread crucial to system operation has unexpectedly exited or been terminated (killed/died).
Hard drive failure or RAM failure often is the culprit in 0xf4 BSODs.
You'll have to run some hardware diagnostic tests. I would start with the HDD diagnostic test, then do RAM.
Both tests are DOS-based, so Windows does not load during boot-up. You will be booting from your system's DVD/CD drive, so you may need to change the "firing order" (the order in which the system determines which device to boot from first -- e.g., the HDD, USB, DVD/CD drive, etc... ).
Make sure that the DVD/CD drive is first in the firing order.
If the system [seems to] skips the DVD/CD drive and attempts to boot from the internal HDD, then there is a problem with the CD disc itself or perhaps a problem with the DVD/CD drive.
I have found that the
CD-R type CD discs work best.
Here are CD-R discs available from Amazon (sorted by lowest price first + FREE shipping) -

I would not advise buying refurbished CD discs.
You'll need at least two (2) CD-R discs -- one for the HDD SeaTools test and one for the RAM memtest86+ test; a few others in case of mistakes/errors.
