Why is My Comp Freezing?

sorry it took so long for me to get back to this, had training for new job this week.

checked the motherboard and everything looked clean on there.

i also tired to turn it on, starting windows either normally, in safe mode, or using last known good configuration. every time, regardless of what i select, the system moves slowly to the black windows loading screen then a blue screen pops up for about a quarter second and then the system restarts. i took a video of the process to see if i could makeout what the blue screen said, and this is what I got:

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

UNMOUNTABLE_BOOT_VOLUME

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

Um, so I'm guessing that this can't mean anything good....

that, btw, was def not the blue screen that i had issues with originally. after checking Microsoft's support section, and knowing that i can't be using the wrong connector cable or BIOS settings since nothing has been changed in the last six months, their suggestion is:

5.At the command prompt, type chkdsk /r , and then press ENTER.

i guess ill be trying this and if anyone has any additional suggestions please let me know

 

Either your hard disk, or the data on it, is messed.

 

i ran chkdsk and my computer is now able to boot up. the minidump folder is empty, not sure if that is related to the recovery. i plan on backing up my files within the hour just in case something happens again.

any thoughts on whether this spells the doom for my poor hard drive for certain or not? i still have no clue how this happened...

 

After trying what was suggested here I still had issues, but someone on another forum was able to help me. Looks like I was only one command away from salvation and a problem-free computer, as I have been for the last week. Thanks again for all the suggestions, and I've posted what ended up fixing my problem in the space below in case anyone else has similar issues in the future.

"Boot from d OS(win XP) cd..on d we'll come to setup window, press 'R', it'll take u to d recovery console window...at the C:>prompt, type "chkdsk /p" (without d inverted commas)/ u may get a message: found one or more errors in d volume after it's done...type: chkdsk /p again and press enter..continue doing it till the message: found one or more errors do not appear...then type: fixboot and press enter...type "y" and enter to confirm...u should be all set."
