Can't start my computer

I mean the thing your power plug plugs into in the back of the computer. They go bad and even though the computer starts the fact that you don't have anything on the screen tells me that if it isn't memory then it's the power supply. Trust me, i've had this kind of problem before so let me save you lots of headaches. Try another power supply if you can. Let me know.

well first chek and make sure the fan in your power supply is running smoothly. a dirty fan will make noise and it's alot harder to keep it cooling plus it really shortens the life of the component it's cooling, in your case the power supply. sometimes you can just put your hand behind the back of your computer and feel by the amount of heat. also make sure there is nothing blocking the way of airflow behind your computer. unless you know how to use a volt meter i really can't tell you for sure how to check it except trial and error which means you need a good power supply to test. as long as you know everything else is good then it's the only thing that could be wrong. even if it powers up the computer it can still be bad which is why it's hard to think thats the problem. try googling "symptoms of a bad psu" and decide for yourself. i wish i could tell you that i was 100% sure but unless you can try a different one that is good i can't. check out the google search and get back with me. and good luck !! well first chek and make sure the fan in your power supply is running smoothly. a dirty fan will make noise and it's alot harder to keep it cooling plus it really shortens the life of the component it's cooling, in your case the power supply. sometimes you can just put your hand behind the back of your computer and feel by the amount of heat. also make sure there is nothing blocking the way of airflow behind your computer. unless you know how to use a volt meter i really can't tell you for sure how to check it except trial and error which means you need a good power supply to test. as long as you know everything else is good then it's the only thing that could be wrong. even if it powers up the computer it can still be bad which is why it's hard to think thats the problem. try googling "symptoms of a bad psu" and decide for yourself. i wish i could tell you that i was 100% sure but unless you can try a different one that is good i can't. check out the google search and get back with me. and good luck !!
