Windows 7 crashed then unable to boot + BSOD

[chris700]

Hi, about an hour ago my screen froze and the computer became unresponsive. I found it a bit wierd that it turned off as soon as I pressed the power button as normally it takes about 5 seconds to do this. Upon rebooting (and going through the 'start windows normally' thing I got a BSOD saying something along the lines of:

'the bios in this system is not fully acpi compliant windows 7'

anyway I googled this and fiddled around in BIOS a bit discovering that my 'acpi 2.0 support' option wasn't enabled so I've changed this. Also some people seemed to suggest removing each RAM module individually and testing each one etc so I did this also to the same effect. After putting them both back in I no longer got the above error message but this one:

'a problem has been detected:
memory_management...etc'

Rebooted again and the BSOD I now encounter and have ever since says:

IRQL_NOT_LESS_OR_EQUAL
.
.
.
***STOP: 0x0000000A...

I found posts about this on this website but I'm not able to get in to windows to access any files and upload them like this person did:

I've since tried booting safe mode, debugging mode etc but each time I do this the computer just reboots and takes me back to the 'do you want to start windows normally or start windows repair' screen. The second option ends up with either a non responsive black screen that can only be escaped by powering off or the above (last) mentioned blue screen.
It might be worth noting; as my research suggests this is something to do with software drivers, that windows did a fairly massive update last night. Although I was able to run my computer for a few hours playing games/internet until this happened. Also in the past couple of months I have upgraded the RAM and GPU but the computer seemed to run fine with these for the weeks since.

Any help would be much appreciated

Regards, Chris
