Windows 7: BSOD every time I try to shut down

Sony Vaio FZ21M laptop. Had Vista installed at first, then I couldn't take it anymore, installed XP. It was hell to get drivers for that. Then 7 came out and installed that, had to get some more driver wizardry on. Sony are pretty up tight about their own proprietary drivers or whatever. Specially with the graphic card.

I started getting BSODs randomly, sometimes closing the Chrome browser (and only happened with Chrome), sometimes during shut down. But now it's always happening.
Here's the log:

If the minidump is needed, I'll post it here.
I've hit the "Check for solution" button, nothing happens.
Please help

Welcome!

Yes, they will need the dmps. Upload then in a zip folder.

Thanks
Here's what I could gather.
I included the last 4 dumps I got while trying to solve the thing. Not that I did much, but it kind of proves that the thing happens ALL the time.
Let me know if I missed something

Without looking at the mini-dump, Its a service causing the problem.

If someone else hasn't identified what service from the mini-dump by tonight, when I get home Ill check and let you know the exact one.

You could also run this in a Cmd prompt (exactly how its written): sc query state= all > %userprofile%/services.txt

It saves a list of all your service names and their exit codes, If you can upload here I can take a look otherwise you'll have to wait till Im home or someone else looks at the mini-dump

Bug Check 0x3B: SYSTEM_SERVICE_EXCEPTION

Yeah I had checked the BCCode 3b for system service exception but reached a dead end in my computer skills so..
Huh... huhhh... the result of that command was:

[SC] EnumQueryServicesStatus:OpenService FAILED 1060:

The specified service does not exist as an installed service.

that cant be good

Try running sfc /scannow from the command line.

Beginning system scan. This process will take some time.

Beginning verification phase of system scan.
Verification 100% complete.

Windows Resource Protection did not find any integrity violations.

Also ran the previous command again, this time figuring out how to run cmd under administrator, but it still says

[SC] EnumQueryServicesStatus:OpenService FAILED 1060:

The specified service does not exist as an installed service.

Did I disable some service?

Bumping I still have the problem, some more help please?

You could try a Repair Install.

Well yeah I could format too, but the whole point is trying to fix things right? I dont feel like things going to default.. that's the idea. Specially cos I had to fish for drivers all over the net, since Sony refuses to give any support on them.
