Windows 7: BSOD after 30 sec after logging in, error 0x0000008e

After I log in to my computer, I would get a real quick BSOD error 0x0000008e after 30 sec and then the computer would restart itself. It didn't matter what I was doing, even if I was sitting idle I'd still get the error. This would happen repeatedly (about 14) and now the computer doesn't turn on at all. By that, I mean that when I press the power button, the LED light on the front flashes real quick, as if it's about to turn on, and then it fails.
I switched out the PSU and the RAM and still the exact same thing happens. I'm about to switch out the motherboard, but I want to run the .dmp files by you guys and see if anyone can spot anything.

This is my dad's computer. I asked him if he's changed ANYTHING at all and he says 'no'. (And he downloads and installs stuff without even knowing he is...I've caught him)

Here are the specs:
Windows 7 Ult 32-bit
Intel Core i3-2120 3.3GHz Dual-Core Processor
Rosewill RCX-ZAIO-92 54.8 CFM Sleeve Bearing CPU Cooler
Gigabyte GA-H61M-DS2 Micro ATX LGA1155 Motherboard
G.Skill Ripjaws Series 4GB (2 x 2GB) DDR3-1333 Memory
Samsung Spinpoint F3 500GB 3.5" 7200RPM Internal Hard Drive
Antec 380W ATX12V / EPS12V Power Supply

I zipped and included all 12 of .dmp files on his hard drive. All of the .dmp files are relevant to this incident. The computer is only 4 months old.

If there's anything else you would like to see, let me know where to find it and I'll grab it. Thank you to anyone that helps me out

Welcome
Your problem is being cause by a Microsoft Security Essentials (anti virus) driver.
A problem with Security Essentials is rare.
If you are running more than one anti virus, uninstall one or the other
If you are running only one anti virus, make a system restore point, and uninstall Security Essentials, and reinstall. If you still have problems Avast makes a great free anti virus, which you may want to try.

Wow, I've never even heard of issues with MSE.
Nope, it's just running MSE, nothing else.

Were you able to find anything else out from the .dmp files? The computer still doesn't turn on at all. I put the hard drive from my dad's computer into another computer and ran a thorough scan disk check. The scan disk found some errors and cleaned it up. So far I've tested out the RAM, PSU, and hard drive, all are good. Only thing left is the motherboard and I'm wondering if the .dmp files might have some info on it

Yourack, I am with you. I tell members to use MSE to avoid problems. That is my AV, too
You may want to update your iastor.sys driver. There may have been a conflict between that and security essentials

Aw man, alright I'll try to update it. First I have to get the computer to turn on though.
I'm gonna try to work on it over the weekend. I'll be glad to give you rep once this is resolved and I'll post the solution once it's all figured out.

Try in safe mode

That's just it, the computer doesn't turn on at all. When I press the power button nothing happens

Not good, any beeps?

No beeps. Just a real quick flash from the light on the front of the case and that's it.
Since it's not POSTing I was thinking that the motherboard just took a dump.

That is VERY possible. Not much more to test from here with that situation.
Wait, try this: Put your speakers on and try to boot. Do you hear the Windows sounds?
