Whenever I try to turn my computer on, it takes many attempts. Anyone know whats wrong?
My computer is an HP Media Center PC m7640n, that is not modded in any way, running Windows XP Media Center Edition. I have had it for almost two years now. One day, I went to turn my computer on, but found that it would not boot. The screen was blank, the hard disk read\write light is off, and my internally mounded SD readers light was solidly on, which would normally mean that it is reading an SD card. (note that my CD tray could still be opened.) So then I held in the power button till the pc turned off, then turned it on again. The same thing happened. So then I unplugged it from the wall, let it completely cool down, then started it again. Everything was the same like last time, but all the fans were blowing full power! It kinda sounded like a dustbuster (portable vacuum). So after many tries (5-30), my computer will finally start up. It works completely perfectly while it's running. But, if I turn my computer off, the same thing happens. The amount of tries it takes for me to turn my PC on is anywhere from 1 to at most (I've counted) 49. So now I just leave my PC on all the time.
I have tested POST
just to make sure that the motherboard is working, by removing both RAM chips and expecting beeps when the computer is turned on. I did hear a series of beeps, which means that my motherboard is OK. I have also tried turning my computer on with no accessories (mouse, keyboard, WiFi, mic, sound, Bluetooth, even the monitor. But still, no effect. I even replaced the power box, still no effect...
I have included pictures of different things I described above, and pictures of the motherboard and the label on the power box. I am almost 100% sure that this is a hardware problem. If you need any more technical information, just ask away in the comments! Thanks!
