So, today I was caching up on the Olympics through the BBC and my laptop turned itself off. It does sometimes anyway through over heating, and has always in the two years I have owned it. Its a Dell Studio 1555, 32 bit Vista Home. Now when I reboot I receive this message:

Windows failed to start. A recent hardware or software change might be the cause. To ficlx the problem:
1. Insert your windows installation disk and restart your computer.
2. Choose your language settings, and then click "Next".
3. Click "Repair your computer".

If you do not have this disc, contact your system administrator other computer manufacturer for assistance.



File: \Windows\system32\drivers\msisadrv.system
Status: 0xc0000098
Info: Windows failed to load because a critical system driver is missing, or corrupt.

This has happened to me before because of updating itunes, which I understand. Could someone please tell me the reason this time? I did not expect Iplayer to cause difficulties. I never received any kids of disks for my laptop and I would appreciate if anyone knew of any was I could save all of my personal files. if it needs to be wiped then if someone could suggest how that'd be awesome!

So, at the mo I'm logging onto the internet using Ubuntu, and have so far managed to save all of my stuff and get my hands on a Vista disk. I tried booting from the disk, which worked. But the 'Repair' option did nothing, and I do not have a 'Format my Computer' option. Deciding to just reinstall Vista and make things easier for myself, I fell short again as it declined my product key, which is genuine and took some finding until I looked under the battery. Even though I was able to bypass this, it could not install first because of the lack of drivers and then secondly aborted the operation after having begun it. So, is there something else I can try, or have I gone wrong somewhere? Thanks!
