Computer wont boot up - Updated

BlackWizard

I just installed a program off my asus cd which overclocks the CPU. Out of
curiosity I gave it a go. After hitting apply the thing freezed my PC.

I shut down the PC manually with the power button then tried to boot it back
up again. The PC powers on, fans are all going, CD makes some noises and the
harddrive light on the front of the case is on but it does not boot up. I cant see
anything at all on the monitor. It just stays in stand by mode.

Ive had this problem about a year ago with a PC. It was when put the CPU settings
up way too high and it wouldnt boot up until I cleared CMOS.

But the CMOS on my Asus A8N SLi Premium wont clear.

I unplugged everything from it.
Took out the battery.
Moved the jumper onto the right pins for a few min.

Put it all back to default and tried to boot it up. But its still the same problem.:(

Any ideas?

Mr. Presentable

Take out the battery, move the pins and power up. Then replace everything. Power needs to go through the circuit to clear the bios.

BlackWizard

Oh I didnt know that

So I should unplug everything from the PC but the power cable.
Take out the battery.
Move the pins.
Hit the power button.

Then start putting everything back?

Mr. Presentable

No. Just move the pins to reset. Take out the battery. Switch it on. That should clear the cmos. Then put the battery back and the pin to normal.

BlackWizard

switch on the PSU or switch on the PSU and the PC?

Mr. Presentable

The PC.

Thanks for the help.

I think I have reset it 10 times over by now.

Not sure what the problem is.

What is the name of the Asus program you installed?

AI Booster

Something along those lines..

Mr. Presentable

I found this. Particularly interesting is the cmos reset procedure.


Sir , Please make sure your 4 pin (ATX12V) power connector installed . And you 'd better also install 4 pin EZ-PLUG on the motherboard .

then please take your motherboard and others parts out off the chassis,put motherboard onto a flat desktop,connect everything needed to boot with,then try to power on system ( remove all external device including system harddisk ),will the system powered on and boot up ?

If not ,Please reset CMOS defualt by clearing CMOS:

1. Cut the power supply for the whole system and open your chassis;
2. Take out the CMOS battery from the battery socket;
3. Install your battery with "reverse side" that means turn the battery 180 degree and put in into battery socket;
4. Hold about 30 seconds, then take out the battery and install it normally;
5. Plug the power cord and Power on .

If still fails , please take all your ram sticks out from motherboard , and power on.Will it give you long-long-long repeat beep warning?
If so , please clean your ram connectors with alcohol or with a clean rubber then install your ram sticks back, you can firstly install 1 stick of ram into DIMM B1 slot to try .(notice : a8n-sli deluxe don't support register memory , or it will lead to system no power , it could support ecc/non-ecc unbuffered memory).
If the system can boot with 1 ram stick , add another.

And please check your SLI connector mode . When you install single video card , please install it to single mode . But if you have 2 video card , please install it dual mode .

If still not , please change other pci express video card or a greater PSU to test .

After above steps if the system does not boot , i think maybe your motherboard or CPU is faulty , you need take a future test for each one and make sure on earth which part cause system won't boot.

If it is due to motherboard damaged , please contact your motherboard dealer to repair/replace .



If having any problems, please don't hesitate to let me know. Let's discuss this issue together.

I went through that step by step.

I got down to the part were it mentions removing the RAM and listening for beeps.

I didnt hear any beeps when I removed the RAM and tried to boot up. But I normally
dont hear any beeps even when its booting up normally

I read this thread http://www.planetamd64.com/lofiversion/index.php/t21816.html

A few people are having problems similar to mine. I guess its the motherboard?
