Question about FIC KT-748 Motherboard

1 Answer

FIC KT 748 motherboard fans run but won't boot to bios.

I thought I needed a new psu. I replaced it. All it does is run but know video signal. I tried different video card. Still the same. Whenever I plug the 4 pin power adapter it won't start at all. It may just start the fans for a second. But when I disconnect, it just runs. I did try a different processor, same results. I did find out the hdd was bad, but it still should boot to bios? Don't understand why it won't power up when I plug the 4 pin adapter in. Maybe I have 2 bad processors. Tried different memory too. thanks cfuller77

    I have the same problem, wont do anything with the 4 pin power connector in. Without the 4 pin connector in it starts the fans etc, but still wont boot.

Onbord cpu running is nodisplay


Just after that there was NO correct answer to fix this problem causes the problem not solved even if it is marked as solved. Me too I have this problem, I was fix it by setting jumpers to default 60 Hz AC power because I won`t have 50Hz AC power or some AC power converter before PSU, I mean this is voltage errors, it`s need to be set to default +5V(60Hz) PSU not +5VSB(50Hz) PSU, (Step1) like might be set to USBPW12 to pin 3 both USB to right side inserted jumper it`s in left side of, near ATX 12v advanced CPU power cable connection socket. Next (step 2) is set up front USB jumpers to +5V or system won`t start up, it`s on motherboard about between PCI1 and PCI2 on right side it must be set to USBPW56 and don`t set it to USBPW78(5+VBS) because system won`t start up, the jumper must be set to right side I mean it`s last jumpers to right side need to be set up, because it`s +5V(60Hz) PSU supply. The USB wake-up feature requires a power supply that can provide at least 500mA on the +5VSB lead when these jumpers are set to +5VSB otherwise the system won`t power up. Next step if it still not starts up its BIOS fault, it`s easy to repair, just (Step3) turn off PC remove BIOS battery (it`s down to IDE cables), start it up wait a bit, then turn it off and turn it again on wait a bit again, turn it off place BIOS battery in to socket to be able save BIOS settings i mean battery is need to save them otherwise settings won`t be saved and Chassis will be broken. (Step 4) Turn PC on press del key after BIOS is load in open Power\Hardware monitoring\Chassis Intruder set to Disable, save settings exit. (Step5) If BIOS (PC won`t power up) it`s Chassis1 jumper fault, it`s need set to Default (Chassis signal, and GND(Ground)), it`s between SATA 2 and SATA1(Serial ATA connectors 7-pin it`s near and down to BIOS battery, the jumpers might be set to right side, after it`s completed repeat Step3 and Step4. CMOS is BIOS battery. If that all doesn't works Take BIOS clearing jumper in it`s clear state, near BIOS chip. Turn on PC with CMOS clear jumper turned on its work. Take beck jumper in its default state after that take bios chip out and CMOS battery out both them an two times restart PC after insert all beck if PC will be working all keyboard flashes once, after its in AC power.

I have an asus p4p800se mobo with 3.2ghz, 1gb ram that just shut off, I rebooted and it went on for a minute or 2 and shut down again, tunrs out the PSU died, I replaced it with a new 500watt psu, now all...


When the PSU died it overstresed the sources on the board - most likely the capacitors were damaged (you can see them bulged). Replace them if you can, otherwise you need a new board.

I have had this motherboard sitting in my PC doing nothing for quite some time. I finally decided to dust the PC off, and it will not boot. When I press the power button, the fans, HDDs and the CD drive...


The user manual will give you the jumper settings but I'm surprised you haven't tried the card you have as you consider it a video problem.

Hello sir, i have one motherboard i do not know is that working or not, so how i cheak from myself that is motherboard working or not


assuming you have a processor all you need is a working power supply unit, memory module compatible with the speed of your mobo, if the board has a built in video adapter you wont be needing a video card and of course a monitor.. put them in the right place and boot up your board by shorting the power switch pins in the function panel and see if it will have an output on the monitor.

Memory upgrade issue


Most ram has to go in pairs. Buy another stick of the 1GB, and it will run fine.

Its the DG31PR bios!
Put a non 45nm CPU on it, update the bios to the latest one , put back your 45nm processor and all should work just fine....this board is awesome.
Cheers!
