The computer showed the BSOD upon switching on this morning. And has shown it upon every reboot. It won't start in ANY mode, and shows 5 error codes.
0x00000024 (0x00190203, 0x83325B28, 0xC0000102, 0x00000000)
Computer says to run chkdsk, BUT this cannot be done because I just can't get past the BSOD. I also can't reinstall the OS (I have no clue if this could even be done with the BSOD in the way.) because I have cleverly lost the disk.
Any ideas?
Apologies for the excessive use of 'BSOD', and thanks!
(Please reply, I really do need help.)

Are your error codes of various kinds, what are they, and can you boot into Safe Mode?

I have listed the error codes given in the way they are written (as to what 'kind' they are - no idea, sorry)
No, I can't boot into any mode
I really am stuck :S

Actually you only have one error code per se 0x00000024: NTFS_FILE_SYSTEM
A problem occurred within NTFS.SYS, the driver file that allows the system to read and write to NTFS file system drives. There may be a physical problem with the disk, or an Interrupt Request Packet (IRP) may be corrupted. Other common causes include heavy hard drive fragmentation, heavy file I/O, problems with some types of drive-mirroring software, or some antivirus software.

Do you have any friends that have PC tech knowledge?

No worries, the problem is now fixed (this usually happens right after I post any messages asking for help)!
For anyone who has the same issue: I reseated everything (that was reseatable) just in case, and then I wiped the HD and reset the pc to factory format (that whole ctrl + F11 thing). Overkill, I know, but it worked. Yes, loss of data, but meh.
Thanks for all the help!
