I know this topic maybe posted a lot but I did go through a search to see if any of the other threads with similiar problems could help me, but none of the descriptions fit mine and I did try the suggestions posted for the other threads.

Okay here's what happened.

During the night I had shut down my computer. The next morning I woke up to turn my computer on it didn't work. I tried flicking the switches on my power supply (the black one with I and O) but no luck. I tried pulling out the power cord and reattaching it, still no luck. I tried both also no luck. So I opened up the box and checked the motherboard. It's recieving power but I still cannot turn it on. I have a 500watt power supply. There is also some sort of screen on the mother board next to the place where you plug the button to turn on the computer. It says 8.3. and switched to 9.C. and various other letters. I have no idea what that means. But I tried replugging the power button but still no luck. I switched it with the reset button to see if it was a problem with my power button but the reset button won't turn it on either. Could it be that my mother board had malfunctioned? I had also tried replugging the power supply with the mother board. No luck also. Could it also be the power supply? Please help

This is an interesting problem. What make and model of motherboard are you using??

As for the letters and numbers, they are most likely to be hexidecimal - http://www.dewassoc.com/support/msdo...exadecimal.htm

Thanks for the reply.

I believe my model is the Abit KV8 Pro V1.1

Using an AMD 64 2800+

It could be the power supply, the motherboard, or bad/loose connections. Faulty componenets can also give similar symptoms.

Have you tried clearing the cmos to factory defaults? (Page H1 of the manual.) Jumper = CCMOS1 near the battery.

WARNING: Turn the power off first (including the +5V standby power) before clearing the CMOS memory. Failing to do so may cause your system to work abnormally or malfunction.

Q: Why the system failed to boot up and nothing was displayed on the screen after I did some over-clocking or non-standard settings inside the BIOS? Is the motherboard dead? Do I need to return it to where I bought from or go through an RMA process?

A: It should not cause hardware or permanent damage to motherboard when BIOS settings were changed from default to over-clocking or non-standard status. We suggest the following three troubleshooting methods to discharge CMOS data, recover the hardware default status, and then make the motherboard working again. No need to bother returning the motherboard to where you bought from or go through an RMA process.

Step 1. Switch off the power supply unit and then switch it on again after one minute. If there is no power switch on the power supply unit, disconnect its power cord for one minute and then connect it back. Press and hold the <Insert> key on the keyboard, press the power-on button to boot up system. If it works, loose the <Insert> key and hit <Del> key to enter the BIOS setup page to do the correct settings. If the situation remains the same, repeat the procedures in Step 1 for three times, or try Step 2.

Step 2. Switch off the power supply unit or disconnect the power cord. Open the chassis cover. Locate the CCMOS jumper near the button battery. Change the jumper position from default 1-2 to 2-3 for one minute to discharge the CMOS data, and then put it back to default 1-2 position. Close the chassis and switch on the power supply unit or plug in the power cord. Press the power-on button to boot up system. If it works, hit <Del> key to enter the BIOS setup page to do the correct settings. If the situation remains the same, try Step 3.

Step 3. The same procedure as Step 2, but in the meantime of discharging the CMOS data, pull out ATX power connectors from motherboard and remove the button battery during CMOS discharging.

Okay I tried "step 1" 6 times and still the computer is still no turning on.
I moved on to "step 2" still no luck.
So then I moved to "step 3" and tried it a few times.
The computer would still not turn on.
I didn't mess with the BIOS or overclocked anything before I shut it down. Should I just replace my motherboard?
I still have 6 months of warranty left.

I had also disconnected and reconnected everysingle part of my computer to check if it was a loose connection

I appreciate the help I am getting

Do you (or a friend) have an extra ATX power supply laying around which you could try swapping out first?
