Elitegroup 848P-A7 Motherboard - Will not boot

Installed a new motherboard and when I turn it on the power supply fan runs but nothing else. The power supply is a 430W/230V box. The peripherals include a Diamond Stealth S80 AGP accelerator card, 1GB DDR memory, and an Intel Pentium 4 Processor 506 (2.66GHz, 533 MHz FSB, 1 MB L2 Cache) chip. I have returned the board once, thinking it was a bad one, but this one does the same thing. Must be something else. Any ideas??

I had this exact problem with a newly bought motherboard and it turned on fan turned but the screen was black, also I noticed once it turned on it wouldn't turn off, (Am wondering if this is the case with you) the motherboard was fine as it is in the other room now working away, so dont get rid of yours just yet. Most new motherboards require additional power to the processor from the power supply, through a four pin power cable, which should be availble with the newer power supply units having (number of pins for you motherbpard power supply) + 4 (which is the 4 pin J-connector) printed on the packaging. If this is connected and you are still having problems which for me was the case, then you will have to try a different approach. Cutting to the chase, the problem I had that produced similar effects of screen being black when the motherboard was powered on, was to do with my case. It was one of those flimsy aluminium foil types. I came to this conclusion by taking my motherboard out of the case and hooking it up to the cases power supply on an insulated surface such as a cork mat. It then was working fine. So I bought a good qulaity case with a new power supply just to be sure, hooked everything up and hey presto it was fixed. It turned out that enough power couldn't get to the board as the cheap case was shorting its supply. Hope this is of some help.

1. Along beep on a motherboard indicates something is connected backward such a a fan or a data cable to the hard drive.
If it is the hard drive cable then you must have pin 1 connector turn around and therefore the mother board is giving a warning.
2. You may have a power supply failure that is the power supply is not giving proper voltage to the mother board.
3. Your ram chip is not properly seated in the RAM slot or in backwards.
4. The CMOS battery to the mother board need to be replaced.

848P-A7 motherboard will not boot. Had for years

This motherboard came out about the time when the bad cap's started being put in boards in China. You might want to look a some of the caps.
on the motherboard to see if any of them look bad. A lot of the motherboards I replace have had them . This is one of the symptoms of a bad cap. You might want to check out Bad caps.net for more on this.
I don't know how familar you are with electronics but in case you need to know a cap is the thing on the board that looks like a tin can. If you see any brown stuff comming out of the top or bottom ,or if the top looks puffed up that cap is bad,and you have just found your problem. The motherboard can be repaired or replaced.

Elitegroup P4M800 motherboard problem get power for 1 sec thats it real puzzle!!

You ask for two problems here, but let's talk one by one.

According to your explanation it seems to be bad wall outlet connector, broken power cable and finally a broken Power supply.

You can check first two, but to you can't check Power supply.

The point the status led is off means that the 5V part of the power supply is broken. 12V part is (probably) OK because you have a fan running for short, but it is not important because all power sources of the power supply should work.

Now, the best for you is first to (try) buy a new strong power supply (you said you have more devices in your PC) and try with another power cable connected to another wall outlet.

First you should see if you get a status led ON. If so, than your PC should work.


Second question:

three beeps suggest bad memory (it depends of the BIOS). If you have more then one module, try with one only and then with oders, but only one at time.

Regards.

Won't boot up

Does it actually power up? (i.e. can you hear any power going through it? do the fans all spin round? are the hard drives powering up?). If there's no power going through it, try a second power supply if you have one.

Motherboard not working correctly.

The way that I solved the problem was to unhook each and every connection to the motherboard except for the 4-pin and 24-pin power supply connections, the processor, the cpu fan and the power on switch connectors, once I have done that, then I plugged in the power supply and turned it on, in which that worked! After that, I would hook everything up to the motherboard one piece at a time, in which after each piece I would turn the power supply on again to see if that was the problem. Starting with the hard drive, the memory sticks and then the DVD drive, and found out that was the problem. The cable between the DVD drive and motherboard was the wrong cable for that motherboard. I will purchase a new cable and see if that works!

No power to motherboard

Hi, Make sure you plug in a 4 pin power connector to the motherboard for the processor or nothing will fire up. It's usually yellow and black.
