Black Screen of Death/Blue Screen of Death

Hello everyone.

I have a Toshiba Satellite L450D-13X computer for the kids, and for the price it's a good laptop. Have had no issues with it until two weeks ago when the screen froze for the boys whilst playing a game and downloading a program from the net. Had to do a force shutdown and since then we have a BSoD on every boot-up. This is what we have tried:

On 'Starting Windows' we are given an option of either 'Launch Startup Repair' which ends up as BSoD or 'Start Windows Normally' which reverts back to the 'Starting Windows' option list.
Any attempt to enter 'Safe Mode' results in BSoD.
Attempting to boot an ISO of the Windows Recovery Disk on a USB key (we did highlight it and promote it to the top) results in BSoD. Borrowing a proper Window 7 installation DVD and highlighting this as an option results in BSoD.

In fact, the only option we used that threw up something different was using advanced boot options. On one of these options we got the Blue Screen of Death with the following information:

Unmountable_Boot_Volume
Disable Bios Memory Options such as caching/shadowing

Tech info

Stop: 0x000000ED (0xFFFFFA80023C2CDO 0xFFFFFFFFC0000185 0x0000000000000000 0x0000000000000000)

I don't mind erasing the hard drive and starting again, there's nothing on it that's critical. I'd very, very much appreciate a steer on this. Checked the web for stuff and nothing seems to assist in any other options. I am not particularly tech literate but can follow instructions.

Thanks in advance.

PS. I have not been able to access any option that allows me to either format the drive, access DOS, or any other options that allows me to try any of the rational things you've set up in your sticky.

I'm in Dublin, Ireland in case you're wondering about the timeline.

[1 - Novice] How to ask for help with a BSOD problem

Hello Carl.

Thanks for your response. I've checked through the other posts and can't find anything that helps specifically. As I have no technical experience it may be that I don't understand what I'm supposed to be doing.

I do believe however, that unlike many other posters, this is a permanent problem and any attempts to bypass it and access the system are failing.

Thanks.
