Hi im josh in cebu phils.may i help you? Friend nothing happens to your motherboard or cannot completely open when the supply current is not enough to support or provide the mainboard.especially if there are many devices attached such as video cards dvd rm etc. you need more power to make them work. so you need to change or use a power supply having a output.500w up.for better good luck hope i helped you.vote so that i'll know if i did it so.

Try replacing the power supply - I had a similar problem that was fixed that way. If that doesn't work, it's probably the motherboard itself. The CPU is also possible - have you overclocked it or otherwise cooked it? Is the CPU cooler/fan blocked with fluff, or has the fan been slow (or stopped) - noisy fan is a sign of bearing stiffness/partial seizure which slows the fan and lets the CPU get too hot. If the CPU is fried, you get the symptoms you describe (MB won't start the PS)

Not sure if it is MB or CPU when i try to turn on computer the only thing that happens is i hear a beeping sound. beep...beep...beep... continually. it wont go to the post, nada. the fans run and i have...


Continous beeps usually mean the motherboard or the power supply, Try another power supply first and see if it will boot, if not the motherboard is faulty, if the prossesor was faulty you would no beeps the fans would run but nothing on the screen. hope this helps.

I switch on my system and nothing happens The cpu


So practically the pc starts but you don't have any image. Try using another monitor and another video card - one of them is dead.

Pc Seems to be dead wont load bios post moust doesnt work or keyboard or monitor


I have the same problem, the CPU fan spins, keyboard lights blink, no start up screen, or bios.
But, when I push a few times on the pc reset button, then the CPU fan is becoming still, the keyboard light are out and I can start the computer again in a normal way.
Can this one be a temporally solution for you too? Do you have any suggestion about?
I guess it can be an electricity dysfunction of a wrong fixed cable.

No signal to monitor.......all dark


and im sure the screen appers to be blank and the key board lights flash once and no feed back other than the fans spinning right? . this is a common problem with asus motherboards and AMD cpu's which indicates a bad motherboard or cpu if you have acces to anouther cpu try changing to that one if that doesnt work you're motherboard is gone

thank you

Either the new power supply you purchased is not functioning correctly. But, assuming it is now that you are getting some form of power to your PC, it is very likely the motherboard. Whatever fried your old power supply (or it could have just been the power supply itself) most likely fried your motherboard in the process. Probably not the CPU since the MB can't even post.
