K, i am really getting annoyed of my computer, i have home premium and never had blue screens after the sp1 update and now out of no were for about 2 weeks now and searching and trying to find out whats wrong, i haven't came up with much. So far i have a problem updating the anti-virus, internet security that i download, i had kaspersky 2009 for a while then one day it didn't work after i got a couple blue screens which i don't realty no what the causes were, then kaspersky wasn't working and i clicked on it and it never came up and didn't show up on my notification bar. So i uninstalled it and i thought that was fine, so then i installed avg 8.5 and it never updated and i though it was nothing so i uninstalled that and install panda w.e, that didn't update, and then ca internet security, then now i have nod 32 which i really like and it dosent update at all, i didn't get my normal blue screens when i installed it which is good but it wont update, my guess is that it is a virus but i scanned wit nod32 and it comes up clean and the problem is still there, so i don't no what the problem is and i need help.... PLEASE!!
