BSOD nightmare help me!!

As a computer simpleton I tried to network my computer to another that had cable internet action. I'm running win2k pro w/SP3 on a sony vaio pcg-r505tlk phoenix bios 4.0. While trying to make a connection I realized I was wy over my head, but the damadge was done. Every time i tried to boot I get a Stop KMODE EXCEPTION NOT HANDLED followed by parameters that after extensive research have yeilded no help (if anyone thinks they will I will post them). I can boot to safe mode, and the event log lists problems with RAS and Telephony service not started since last boot. The BSOD suggested i disable BIOS caching and shadowing which to date I have been unable to figure out how. I have tried to run chkdsk, but my system says that it cannot gain exclusive access to C: drive. I purchased fix-it utilities only to find that I cannot install programs in safe mode. Fix it is on a bootable disk which has a few recovery tools, one similar to chkdsk, whick gave me the same problem (exclusive access). Considering that I no longer have my windows CD-ROM, I'm really between a rock and a hard place. Any suggestions available to this minimal data would be greately appreciated.


Thanks,
