BSOD shortly after bootup

[cav]

I have been having this ongoing problem for a while now which I've just been ignoring but I think it's time I probably ask for some help. My PC, more often than not, gets a BSOD witht he message "SYTEM_SERVICE_EXCEPTION"after boot up. Either
a)I'll start up the computer, it'll boot into my desktop, I'll wait a few minutes, it'll BSOD, reboot, go back into desktop and then everything will be completely fine (I'll get the "windows has recovered from an unexpected shutdown" error message).
or
b)I'll start the computer, it'll get passed my motherboard info screen, screen will be black (though my monitor light is still on and I can hear my PC running), I'll have to hard restart it and when I boot back up everything will be fine (I'll also get the "windows has recovered from an unexpected shutdown" error message)

I'm pretty sure I have all my drivers updated (windows update says so and geforce experience says I'm up to date as well, but is there anything else I need to check?).

I've been told that this is either a problem with windows or my hardware. I planned to reinstall windows once I got my SSD but that wont be for a few months, and I've checked inside my PC for unconnected parts and stuff but everything seems to be fine.

here are my specs if needed:
CPU: AMD FX-6360 @ 3.9 GHz
GPU: Gigabyte GeForce GTX 660
RAM: 8GB DDR3 1333 (4*2)
HDD: Western Digital Blue 1TB
MOBO: ASUS M5A97 r2.0
OS: Windows 7 Home Premium 64-Bit
PSU: 460W coolermaster elite atx12v

I'll post a picture of the BSOD the next time it happens

I would be checking your memory. I suggest you remove them both then just put one back in and see if the machine boots ok and then try the other. It may be something else but, it sure sounds like Memory trouble.
