Booting in circles

Yesterday my computer started acting up on me. When it starts to boot Windows XP i get a "we apologise for the inconvenience but Windows did not start successfully...." It give me 5 options to boot XP -
Safe Mode
Safe Mode with Networking
Safe Mode with Command Prompt

Last Know Good Configuration (your most recent settings that worked)
and
Start Windows Normally.

And none of these options work, they all take a long time but keep the machine going in circles ie. it shuts down and restarts giving me the same problem. Interesting fact is that on the last two options (last known good config and start normally just before the machine give up i see for about a second the "normal" windows start up screen with blue bar running across.

I have tried the Product Recovery CD that came with my machine. the recovery console was useless.
i have also tried to reinstall windows from the CD however it found a problem with the partitioning and to reinstall i would have to loose all the data on the machine

I don't give a shit about any files or anything of the sort. I just the fastest way to get my computer working again, even if it involves reinstalling windows from the CD [which I have but do not know hoq to do.]

I heard if you download porn to your computer you can get viruses, but sometimes, they infect your body so your weewee might fall off, hope this helped

recovery console then fixboot then fixmbr then chkdsk /r c:

alternatively download ubcd4win and mount to a cd and boot from it and save your data to an external unit (pendrive or hdd, make sure you connect the external unit before you boot) then format and reinstall

Your computer is blue-screening but since it's set to automatically restart, you never see it (or the error message it has).

Restart you PC, smash F8, then select "Disable Automatic Restart on System Failure.

It should then at least STAY on the blue screen, post the message when it does.
