Corrupted Registry Files?

I'm currently running XP and have been getting the blue screen of death almost to a tee every 5 min. I was able to narrow it down that it was my CSRSS.exe file (got this from the dump file). I will clean the registry and then after 5 min get the bsod, I reboot and I still get the same errors.

I installed a new program last wed, and it didn't start crashing until after Mozilla updated itself. Any suggestions on how to get this computer to stop getting the BSOD.

 

What is the error on your BSOD?

 

It says

Techincal Information

Beginning dump of physical memory.

I uninstalled the software I installed, and I can't log into safe mode (it freezes)
