Ok I have eliminated the problem that it may be RAm I am actually now fully on the virus approach now, The RAM was merely not seated correctly and appears to be fine after I took it out and cleaned up and put it back in.
So whats going on with my PC now .. well the CPU is running at 100% and for no apparent reason as well. The main process biting up process space is McShield.exe which is a McAffee internet virus protection thing.
I have scanned my computer and found Netsky in a couple of .eml files that McAffee Spam Killer had prevented me from accessing anyway. I am thinking that an update from McAffee has messed up my system again, so I am going to delete McAffee completely off my computer and then reinstall all the services again.
I had this problem once before with the software where by my whole pc was really badly screwed up, Windows updates have done the same thing, I amnot so sure this auto updating crap is all its cracked up to be if it messes my system up like 3 – 4 times a year.
