Is there any chance I could get some help as well, in sydney Australia. I need a complete diagnose of my pc, it heats very quickly and works very very slow. Yet I have bought it several months ago (it is a second hand computer). However, I did not have any issues at the beginning, so I guess it is me who did something wrong with the computer. I tried to go to a it support sydney , but couldn't find anyone to solve this issue. I'd appreciate any insights on this matter. Thank you in advance!
