1.	Solve : PC wont turn on. Maybe bad MOBO??
Answer» Hey guys, Newbe here..I am having some issues with my computer and I can realy use the help of someone more knowledgable than me. I built the pc myself about 1.5 years ago, never realy had any major issues with it until now. Its a Vista 64x operating system. ASUS MOBO..I cant find what model it is AMD Athlon x2 processor @ 2700gzh I used whatever power supply came with the case, which was either 450 or 500 watts. So this morning I know the power in the house went out for a second, and then turned back on. I dont know if we had a power surge or if someone in my house manually flipped the breaker on and off. My computer was hibernating at the time and when it happened I did hear the MOBO beep. So if I try to turn the computer on I dont hear the MOBO beep at all. The power supply and the CPU fans go on, and I can hear the hard drives spinning, I cant get any signal going to my monitors. I have tryed it with two different monitors. The light for the MOBO is still lit. I tryed different connections to the monitors, hdmi, vga and DVI which is what I normally use. The monitors still dont get any signal regardless of what cable I use. Just trying to diagnose if the graphics went out on the MOBO, I LOOKED in my drawer and found my old graphics card. Its a ASUS EAH4670 external graphics card that I used to use before but had to STOP because it would go out after a few minutes..I installed it, restarted the computer, and still no signal to any of the monitors. what do you guys THINK I should check? I cant get into the BIOS settings because of the no signal being displayed on the monitors..

Try another PSU.Does your MONITOR work?? sounds like more of a video card problem than your motherboard... check and make sure your monitor WORKS by connecting it another computer if you have one.A friend of mine had a problem similar to this after a storm. Her computer made a noise and shut off after a power surge, and for two weeks she waited for me to get over there to try and look it over. She said she could not get the computer to turn on, and was afraid it was fried. Actually all I did was unplug the power cord from the back of the computer to the power supply for about 30 seconds, plugged it back in, and everything worked. Hopefully it's something simple. Otherwise I would try a new power supply, and testing a basic configuration of just the video card and one stick of ram to see if you can at least get a display on it. They say on a decent computer, the power supply would fry before the motherboard as a safety feature.Another quick thing you can try.....unplug the PSU from the wall... Toggle the on/off switch (not the 110/220 switch) a few times... Plug back into the wall and give it a try...

Hey guys,
Newbe here..I am having some issues with my computer and I can realy use the help of someone more knowledgable than me.
I built the pc myself about 1.5 years ago, never realy had any major issues with it until now.

Its a Vista 64x operating system.
ASUS MOBO..I cant find what model it is
AMD Athlon x2 processor @ 2700gzh

I used whatever power supply came with the case, which was either 450 or 500 watts.

So this morning I know the power in the house went out for a second, and then turned back on. I dont know if we had a power surge or if someone in my house manually flipped the breaker on and off. My computer was hibernating at the time and when it happened I did hear the MOBO beep.

So if I try to turn the computer on I dont hear the MOBO beep at all. The power supply and the CPU fans go on, and I can hear the hard drives spinning, I cant get any signal going to my monitors. I have tryed it with two different monitors.

The light for the MOBO is still lit.

I tryed different connections to the monitors, hdmi, vga and DVI which is what I normally use. The monitors still dont get any signal regardless of what cable I use.

Just trying to diagnose if the graphics went out on the MOBO, I LOOKED in my drawer and found my old graphics card. Its a ASUS EAH4670 external graphics card that I used to use before but had to STOP because it would go out after a few minutes..I installed it, restarted the computer, and still no signal to any of the monitors.

what do you guys THINK I should check? I cant get into the BIOS settings because of the no signal being displayed on the monitors..
