I have Foxconn 45GMX-U with P4 and DDR2 and in some day the electrical voltage increased suddenly which cause damage to the power supply and burning the power cable, i bought a new power supply with cable and this problem appears "no beep no display on screen"
however the temporary solution that i have got is to reset jumper or "clear CMOS" but the problem still appear again and again with losing the sound after that problem . plese people help me to fix this .

Re: no beep no display
If you have had an electrical power surge.
It,s for sure that you have caused damage to the Motherboard-CPU And possibly The RAM ( Memory ) There is no fix for this. I,d suggest New Power Supply Unit. New Motherboard. You can then Try The Memory And CPU On The New Board/PSU.
You may be lucky And the memory and CPU May have survived.
It seems as if the motherboard has suffered the damage.
I,d also suggest investing in a surge protector also, once bitten twice shy.

Electronic components are very sensitive to voltage surges, spikes or sags.
Voltage is not delivered at a constant 120 volts. With alternating current, the voltage rises and falls in a predetermined rhythm. The voltage oscillates from 0 to a peak voltage of 169 volts. Most appliances and electronics used in the United States are designed to be powered by this form of generated electricity.
During a power surge, the voltage exceeds the peak voltage of 169 volts.
A spike in voltage can be harmful to appliances and electrical devices in your home. An increase in voltage above an appliance's normal operating voltage can cause an arc of electrical current within the appliance. The heat generated in the arc causes damage to the electronic circuit boards and other electrical components.
(Smaller, repeated power surges may slowly damage your electronic equipment, over time too.)
Voltage sags, a.k.a voltage dips or brownouts, is another form of electrical disturbance that can damage appliances as well.
The bottom line, power surges, spikes, and sags can vary in duration and magnitude; and can damage electrical equipment ranging from stereos to computers to any household appliance that uses chip board circuitry sensitive enough to "blow" due to over or under-energizing it.
According to Intel 945G chipset supports Celeron D up to Core2Duo. Intel
Gigabyte's 945 DS3 even supports up to Core2Quad. GByte
Foxconn has 3 mobo bios from there site. Foxconn
According to their date: Latest to oldest
4BFF1P56No Version4BFF1P40 Have you tried installing the no version bios?In my experience some latest bios have some problems with other devices so try to use the no version bios. or try a different mobo bios with the same chipset from Foxconn. below are two foxconn mobo models i can't see the difference. 945G7MA-8EKRS2945G7MA-8EKRS2H Update at your own risk.. hope this helps, thanks for posting.
Its a memory problem obviously. Try dusting the memory slot and try inserting the memory into the slot a couple of times. If still not working, the memory may be incompatible(rarely, there are brands of boards that doesn't suit to certain brands of memory), or it may be damaged.
You're Foxconn board uses the Award bios. The long beeps you are hearing are telling you there is a problem with you're memory. You're pic does not look like the Foxconn P9657AB-8EKRS2H MB as shown in the user manual. Found on This link. http://www.foxconnchannel.com/product/Motherboards/detail_overview.aspx?ID=en-us0000297 The pic on Foxconn's site does but not the manual listed. The motherboard uses four 240-pin slots with 1.8V for DDR2 memory only. (Question? Did you're ECS MB use DDR2 memory)? If you have more than 1 DIMM installed remove all but 1. Move the DIMM into the closest slot next to the CPU. Boot the PC & check for beeps. If still presant move the DIMM to the next slot & try again. Continue this through all four slots. Than try another DIMM. If the mother board continues to beep as mentioned than call Foxconn. (There is a bios update mentioned below for memory). The CPU may come into question. (It’s revision). You may have to call Foxconn for this information. (580-272-0035). They do not place this information in their user manual. Most users have to call. The rev of the CPU may conflick with the memory causing you to receive the bios beeps. (I have had to return 2 boards for this reason). I picked an Asus board over Foxconn. I have come across this with Foxconn motherboards these past two years. Suggest you update you’re bios. Foxconn has a revision dated, 3-28-2008 for memory before you call. After bios update test the memory again for beeps. Still there? Return the board is my suggestion. It’s a guess that the red led will go away after the memory issue has been addressed. Normally there is a green led on most motherboards. This means standby. The board has power connected. I could not find any reference in the user manual * .pdf, for R450. Good Luck ninjo61! Mike
