Re: HELP my computer wont turn on...
yeah i had a simular problem to that, I used to have an older hp desktop that could only allow 512mb of RAM on the mobo max, and I tried putting another like 168mb or something like that on it, and right as I put it in and turned it on i got 3 beeps kinda like what you said and it won't turn on again, i think i fried my motherboard but I am not sure about your problem....could it be the power supply?
