i turned my com on the other day and now when trying to install anything from comodo firewall to well just everything i have downloaded it freezes my whole pc . i have tried downloading hijackthis to get an analyisist to post here for someone to look at but that too freezes my com and the only way to do anything is hold the power button to turn off and restart . even clicking start and trying to open folders such as documents downloads etc freeze my pc too ... does any one have a solution to this . i have tried system restore to when it worked ok but still the same issue . i use ccleaner once everynow and again and have restored that back to a date when i know everything was working .

my com did not come with a disk so i cant do a repair install , i have a recovery disk tho but really am trying not to do a clean install as im on a limited data plan and downloading everything including all the sp1-sp2 updates will take up lots of my data
