I was recently on these forums looking for help since my computer randomly slowed down dramatically. There was no malware on my computer and I was sent to this forum. My computer has become unbearably slow. I have even factory reinstalled it and after installing my programs and putting my files on it it is STILL slow. the CPU is always at 100% even though if i order the list of processes by CPU % it rarely adds up to more than 30-40%. I used to be able to use video chat on skype, surf the web, use thunderbird, microsoft office programs all at once but now i can only do one at a time. also, firefox never quits fully and keeps telling me the process is open so i have to go close it via cntrl-alt-delete and then restart it.
does anyone have any ideas as to what is wrong with my computer? i would greatly appreciate any and all advice.
