Re: Model: VPCL222FX Computer has a mind of its own!

I just thought of this simple but seemingly neglected by many . . . . when was the last time you opened the hood and with a soft brush attachment carefully  vacuum around the fans, and intake(including the filter)/outtakes.   If this has not been done in awhile --- overheating will do weird things including a complete meltdown occasionally (they say).

I posted then reread your mention of the beeping, which kind ah reminds me of something so ... using "computer annoying beep, or sometimes a quick double beep " as keywords into google.ca  search field  acquired a few 'articles'  and quite a few do lean towards overheating.    And maybe these are items you have already tried !

nite,

D'

p.s.  during my reno' of my VPCEL',   I stripped off  avg' (it was getting intrusive) and spybot'.. replacing them with   MSE for a  AV(on Win7pro platform).   https://support.microsoft.com/en-ca/help/14210/security-essentials-download

I am contemplating (based on a article recommending a AV/malware combo, which i can't find tonight)   loading on your mentioned,  'malware bytes(free)',   which is said to suffice as a operator induced checker that doesn't conflict with majority of AV software.
