Hi recently my PC has just randomly playing up, when i play games my monitor will randomly lose input connection with my pc while my pc stays on and the back fan starts blowing out alot of hot air, i have never had this problem before in the few years i have had this custom built pc. I did open up the case and it's a little dusty inside so i will get to cleaning it tommorow morning to see if it helps but i was wondering if there is any other suggestions i could do to try solve this issue, thanks.
