blue screen while trying to boot up in safe mode

I have been trying to boot up in safe mode for about a week now ( it's been so long I can't remember why I wanted to )  Anyhow I keep getting a blue screen with a stop code of 0x0000007e (0xc0000005,0x876799d,0xf8b06c84,0xf8b06984)  I am running XP Home on a DELL Dimenson 2100 and have had no problem for the last two years when I had to open in safe mode.  A couple of weeks ago I got a remote keyboard and mouse, but did not like the response, and went back to the old units.  I removed the software from when I installed them.  I also got a Belkin 2.0 USB hub that XP wouldn't reconise, so I took it off and set it aside for now.  These are the only things that I have done in the last few months although it's been probably 6 months or more since I needed to go into safe mode.  ANY IDEAS? 

PS:  I tried DELL support they suggested I try System file checker which relpaces all system files  (did not work)  They also said try system restore (did not work) next they suggest a full OS system overwrite (I haven't tried this yet because they wouldn't answer my other question  which is if I do a full system overwrite will I have reinstall all my other software for my other programs)?
