My computer uses a P23G motherboard from PC Chips (V3.0) and I'm having a very big problem. I tried the CPU overclocking function (big mistake) and upped the frequency a little bit. As soon as the computer rebooted, it started making a faint clicking noise and the screen was blank. I quickly disconnected the computer and looked at the manual for the motherboard.
I disconnected all the power from the board as directed (at least I think I did) and then used the "Clear CMOS" jumper for a few seconds.
Now, when I went to hook all the power back up, I realized I didn't know where the power switch/LED connecters went. I know where the panel is, but each seems to go in a particular spot and I have no idea which is which. Right now the reset button is booting the computer (but my monitor still says no signal) and the LED light on the front is red...
Is the blank screen caused by these connectors being in the wrong spot? Or do I have yet another problem?
PLEASE HELP! Any help is greatly appricaited! Thanks a lot!
"Is the blank screen caused by these connectors being in the wrong spot? Or do I have yet another problem?"
Better get the Panel1 header straightened out first.
Check page 12 of the manual for that MOBO.

ATo add to Doctor's response, what was meant by "disconnected all the power from the board as directed" was simply to unplug the computer from the wall socket. Clearing the CMOS when the computer is plugged in doesn't work.

set the CMOS jumper to clear for a few mins and/or remove the cmos battery. i am only 12 but this method worked for me when i over clocked my pc. If you want to overclock make sure the cpu is getting enough voltage. Overclocking is NOT reccomended.ok and like 0thehill said unplug it when you clear cmos. hope you get it working. post back if it starts working again.

I believe I have the right pins now. (There was a number 1 next to the lower left pin, so I assumed the one above it was number 2, then number 3 was next to 1, etc.)
Still, my monitor says no signal...what do I do now?
Thanks!

Depending on what settings you changed you may have damaged one or more of the components. You could try the clear CMOS again using the method described above. If that doesn't work you could try removing and reinserting the video card and memory sticks. If that still doesn't help I would suggest not spending andy money on a system that old.

Opps, I read the specs wrong, New system afterall. With the rig you appear to have, you most likely didn't damage anything. Sort out the wiring issue.

Well, I'm pretty sure it is sorted...the LED is green now and it sounds ok...
When I boot up the system beeps, then a pause and then beeps twice. I believe it only beeped once (twice max) when it was running normally so its probably outputting some error I can't see!

sounds like a video card fualt i THINK. try or borrow a videocard to test. try a pci one. resetting the cmos may have changed video boot from agp to pci. if you are using onboard graphics you are probbally screwed. the beeps may also mean bad ram. try some modules you know to be working. just HOPE it has not damaged your cpu. i think it is a ram error more than a bad video card. try both and post back if all is ok. i am only GUESSING. good luck!!

My guess is based on what you say you did just before this behavior occurred. Overclocking generally won't damage RAM or a display adapter.

I doubt the CPU is damaged. There should be a high temperature cutoff.
AMI post codes indicate 1 long & 2 short is a failure in the video system. An error was encountered in the video BIOS ROM, or a horizontal retrace failure has been encountered.
I interprete this to mean you MAY have damaged the integrated video chip. If you haven't tried clearing the CMOS the proper way you could try that. If you have an AGP graphics card you could put in there that MAY solve your problems.

I'm using an AGP graphics card right now which was working fine up until I tried the overclock utility. So does this mean it is the CPU?
Thanks again for all your help guys!

IT WORKED! I'm back in Windows! Thank you all so, so much. Turns out it was actually running setup but I wasn't giving it time to finish (I couldn't see what it was doing.)
Thanks again!

Yep! I don't have another PC with an AGP slot to test the card elsewhere...I'm not sure why that PC won't use it anymore.

If the card is still under warranty contact the vendor and get an RMA number.
Finally, IF you decide to try overclocking again, find out how to do it the right way. Read the threads at this forum under the overclocking section for awile.

Now that you've got it booting again, try putting the video card back in and see if windows detects and reinstalls it. There may be nothing wrong with the card at all.
