As I've stated many times in the past, I am ignorant of all things computer. I could now use some help! My computer has developed the nasty habit of freezing up after 10 minutes or so of use. It doesn't seem to matter what I'm doing at the time. The mouse and keyboard just become totally useless and I have no choice but to power down. Acting on a suggestion that it may be the power supply, I opened the computer up and powered up to wait for the freeze to see if the power supply was hot. Nope. Now one thing that also has happened a couple times is the cd draw opening by itself. Also, on two occasions while it did not open, I hear a clicking eminating from it. Or at least I think it comes from it. Any ideas on how I should proceed?
