BSOD when trying to start up ANY mode - Startup Repair/SysRestore Fail

I'm sorry but I can't follow all the BSOD post guidelines because I can't get into my computer! I took a screenshot with my phone though, sorry for the bad quality.

First, some computer info:
Windows 7 Home Premium, 64-bit (Vista 64-bit was OEM)
Computer is 3 years old. Installed Windows 7 maybe 1.5 years ago
4GB RAM, 750GB Hard Drive
Intel QuadCore Processor (Can't remember which one, sorry), 2.66 Ghz
No Viruses, Memory Problems, etc. - I ran a full scan with Malwarebytes and SUPERantispyware just yesterday and they came clean.

Today I restarted my computer because my USB Flash Drive wasn't being detected. However, it would not start back up. I did NOT download anything new recently, and my latest system update was maybe 2 days ago.

When I try to boot up my computer, i get this BSOD error.
- This happens when I try to start it up in Safe Mode too (and all of the other Safe Mode options).


A process or thread crucial to system operation has unexpectedly exited

Here are those codes listed at the bottom. Not even sure they matter but I took several pictures and managed to get the whole thing...
0x000000F4 (0x0000000000000003, 0xFFFFFA8007522B30, 0xFFFFFA800750A340, 0xFFFFF800339AF40)

I tried System Repair, but the wizard said that this error could not be repaired automatically.
- To fix this I tried the infinite loop technique (https://www.sevenforums.com/register....2959acad0ae9f2), but this didn't work.

I also tried System Restore, which said it worked, but I still get BSOD when I try to restart my computer after the successful System restore.

I also tried inserting my Windows 7 disk and setting the CD drive as default BIOS. I came up to the Windows Setup and tried doing a System Restore/System Repair from there and nothing special happens. The System Repair says it doesn't work (and the System Restore says it does).
- I also ran the Memory Diagnostic Tool from the Startup Disk and it came clean. Not a problem with memory I suppose?

A few other things I've tried...
Command prompt things like 'chkdsk' and 'sfc scannow'. These either came out clean or said that my computer needs to be restarted before the command is entered in order to finish System Repair (and when I restart it says the same thing).

Please help, and thanks for taking the time to read this!

Here's some info on the STOP 0xF4 (the 0x000000F4 part of the message): BSOD Index

Try these free, bootable diagnostics. At the Antivirus link are some links to bootable antivirus disks, please use one of those to scan your system:

I suggest starting all troubleshooting with the following diagnostic tests. They'll save you a lot of time and heartache if there is a hardware failure, and you'll have the disks on hand in case you need them in the future:

H/W Diagnostics:
Please start by running these bootable hardware diagnostics:
Memory Diagnostics (read the details at the link)
HD Diagnostic (read the details at the link) - Test ALL of the hard drives.

Also, please run one of these free, independent online malware scans to ensure that your current protection hasn't been compromised: Free Online AntiMalware Resources (read the details at the link)

Thanks, I'll try those.

Edit: Running the Antivirus (I chose AVG) now, followed by Memtest.
I first tried doing the HD one but the computer wouldn't boot it for some reason.

Imcredible,

Microsoft now offers an online malware scanner and better yet, a standalone malware scanner/remover.

By standalone, that means you put the scanner onto a usb stick or a dvd and then boot from the usb/dvd, this gives you independence from any malware on the harddisk.

Here's a link to a tutorial on the standalone system sweeper. If you have questions re its use, then let me know.

At one time, I tried all of the "boot" versions out there.

I recommend and recommend only Microsoft Standalone System Sweeper.

The booted scans seemed to show no infections.

Somewhere I'm lost here. what is a booted scan?

did you run the Microsoft Standalone System Sweeper? Yes or No.

Now as to the iso problem.

although I haven't visited the site to see the recommended tester, the tester is probably the same one which I've recommended and that has been around for awhile.

The iso has to be burnt to cd and then you boot from the cd.

In win 7, all you have to do is click on an iso and autovatically the dvd burner will pop up. If you want a more general approach then use IMGBURN at 4x and with verify.

Now here's the hitachi link which I use:
Hitachi Drive Fitness Test
