Hi I need some help with my pc, firstly, if I leave it off for a period of time, i.e. over night, when I go to boot up in the morning, the power supply is making a lot of noise, it takes 7 or 8 attempts by pressing the on off switch before I can get it to boot up normally, I am sure it is the power supply that is making this noise, the fans are putting out a lot of cold air so I know it is not the fans. I am sure I need to replace the power supply, once it is working it can work for days until I turn it off again and reboot it after a few hours. How can I easily find out what power supply I need without sighted assistance? The power supply is the type with a switch at the top. Secondly I would like to increase the ram, is there a way for me to find out what type of ram I need to get?
