My computer is fine until I try to access the internet. I've had the firewall on so it doesn't crash, but I can't do anything to help it without an internet connection. I'm now using my laptop. This is what the blue screen says:

A problem has been detected and windows has been shut down to prevent damage to your computer.

KERNEL_DATA_INPAGE ERROR

If this is the first time you've seen this Stop error screen, restart your computer. If this screen appears again, follow these steps:

Check to make sure any new hardware or software is properly installed. If this is a new installation, ask your hardware or software manufacturer for any windows updates you might need.

If problems contiue, disable or remove any new hardware or software. Disable BIOS memory options such as caching or shadowing. If you need to use Safe Mode to removeor disable components, restart your computer, press F8 to select Advanced Startup Options, and then select Safe Mode.

Technical information:
*** STOP: 0x0000007A (0xC03DE188, 0xC000000E, 0xF7862642, ox52976860)

*** ftdisk.sys - Address F78642 base at F7858000, DateStamp 3b7d8419

I looked this up and this is what I found:
This error indicates that Windows NT wasn't able to read a page of kernel data from the page file. A virus, bad memory, a bad processor, incorrectly terminated SCSI devices, or a corrupt PAGEFILE.SYS file may cause this situation. The first step in correcting such an error is to recreate the PAGEFILE.SYS file and see if you can bring your system back online.


What should I do? I don't want to damage the computer (any more than it already is). I've considered a system restore but I'd like it as a last resort.
My computer is a Windows XP SP2. I'm not computer savvy so not sure what additional info to post (or where to get that info for that matter). Please Help!
