System Freeze - SF Diagnostic Files attached

[Matt123]

Hi,

I have a Toshiba a200 Satellite laptop running Windows 7 Ultimate 32 bit (which I recently installed as a fresh install to try and solve my problems). I have several problems, and I'm not sure if they are related or seperate to each other. Here they are:

• Often, when I am away from the computer, even if it's only for a few minutes, when I come back it is frozen -- the screen looks normal, but the mouse won't move and the system won't respond to Ctrl + Alt + Delete. I have to hold down the power button until it goes black, and then reboot.

• Often when I reboot, and almost always when I boot up for the first time of a morning, the computer fails to start -- it will get to a black screen and freeze forever, or it will freeze on the "Windows is Starting Up" screen, and I will have to hold down the power button again to shut it off. It will usually start after the second or third time.

• Sometimes, firefox (and sometimes other programs too) stops responding for about 30 seconds, and then comes back fine. It's not that bad, but it seems a bit odd. This is just a minor annoyance -- the other two problems are more worrying.

I've attached a zipped folder containing the reports from the SF Diagnostic Tool.

I hope someone can help me. I'd be really grateful.

Thanks,

Matt


EDIT:
Not sure if this will help, but the system has frozen twice in the past few hours, and this error occured both times in the event viewer:

Session "Microsoft-Windows-Setup" stopped due to the following error: 0xC000000D
