just wanted to add that I may have found a possible 'temp fix'.
Don't wanna jinx myself by saying it but, "things seem ok now"
I unhooked power, took CMOS battery out, left machine alone for approx '2/3rds a can of beer drank at a slow to medium speed",
went back booted up, defaulted bios settings, reinstalled windows and presto for the moment things are looking good.
Prob' not the best of 'psuedo fixes' but well worth a try before going out spending money on hardware.
Once more, thanks to all the people that took the time out to reply to me, appreciate it
