power supply help

I am a bit bewildered here. I play Eve Online and run multiple clients. Each one of them seems to be drawing a lot of power.

Please help! My ENVY 24 all in one is constantly bombarded with "ghost" touching when the touch screen driver is enabled even though I've never used it as a touch screen and the screen is spotless. I'll be working and periodically dots appear on screen in random places like it is being touched...

So , when ever i turn on my pc it shuts down automatically then after pressing the power button again it create beep noises, then after third time it starts normally. After i changed ram slots the problem was solved, but it starts occurring after 1 month again! Can you tell me any permanent...

I wanted to build a PC but never got around to finishing it. With me going off to college I need to just get rid of unused parts sitting around in my room. I'd appreciate a price appraisal for each part individually. Please and thank you! Motherboard: Asus M4A87TD Evo PSU: Rosewill Stallion...
