Cannot re-install Windows

I have a program called Tweaking.Com, it has an option to run Chkdsk at boot. Last time I

rebooted the program got to 10% than stopped, tried rebooting several times and no change.

Tryed to reset to factory by using my Win 7 disk(I used this disk on this computer several

times in the past as the F9 key does not reset to factory), When the disk is finished the

installation I get an error message, "Computer restarted unexpectedly or encountered an

unexpected error. To install windows click OK and restart". This just keeps repeating , will

not install. Any help greatly appreciated. Compute is a HP6142, i3, 650HD, 8G Ram

 

You may have it stuck trying to run Chkdsk.
If you happen to have another HDD that is the fastest way out of the loop. If you don't you can try wiping the offending HDD in another computer. A format may not do it, wipe it to be sure.
