My PC is part of my bread and butter that is why I do my best to take care of it. If money permits, I will buy him (my PC is a guy, LOL!!) additional computer memory since I am also more into graphics manipulation and digital scrapping. Aside from that, maybe a PC vacuum will do to help get rid of dirt clogging his internal paraphernalia and the keyboards.Love your PC and it will love you back with years of great service!!
After my 403 forbidden incidents, I got my PC reformatted. I badly need it because of some viruses hanging around my PC. Well, they are not that harmful but very annoying.
