XP & Restore problem

I am running XP Home & when I try to restore my computer to an earlier restore point, it goes through the process, then ultimately ends up saying it was unable to restore to an earlier point. I've tried several times with no luck.

I have installed some programs that could be a factor. I have used the Registry First Aid program & think it might have deleted some links/info I needed. I also have the Dantz Retrospect & PowerQuest Partition Magic 8.0. I have my first hard drive partitioned as C & H (the Dell diagnostics). The second hard drive is partitioned as G & I. I have some programs on the second hard drive that won't automatically pull up when requested off the C drive containing the OS. I have a third external drive K, but use it only for backup.

In an attempt to get the restore to work, I disabled all but C drive & it still didn't work. Any help appreciated.

If you think you have done something to prevent the "Restore's" function, why not use your back-up? (Drive K)

 

I eliminated the original from K & do not have a good backup now. Thought I had everything going ok at the time.

 

it has become corrupted
turn it off the back on again,to start fresh
