Question about Foxconn C51XEM2AA-8EKRS2H (0683562100229) Motherboard

3 Answers

No POST I have the Foxconn C51XEM2AA motherboard and installed everything according to the manual (this is not a first install by any means, been building computers for a long time). When I hit the power switch, everything lights up, fans start moving, hard drive starts moving (when its plugged in), but I have no display. I tried plugging video card (XFX 8600 GT) into the other x16 PCI slot, using only one memory stick (I have two OCZ PC 6400 1 gigabyte sticks), using each one on seperate occasions, took everything out and reinstalled and still nothing. Something to note is random LED error code readouts, but mostly getting error code 02. Ive gotten error code C5, 02, and even what looks like dA (that one wasnt even listed). I have a Rosewill 500w power supply, and have no way of testing other PS because none have the 20+4 connector needed (the other ones are only 300W anyway, so I dont even think they are powerful enough). I also have no way of checking the components individualy because all the computers in the house are ancient (the reason im upgrading in the first place)I should mention i used Arctic Silver 5 thermal compound, and was afraid somehow i shorted the board, but after removing the CPU and checking thoroughly with a flashlight I found no residue on the board. Pretty sure its just a DOA, may have to RMA it. Any suggestions?

    I forgot to mention that I have no idea what error code 02 means, it tries to describe it in the book, but it makes no sense to me...

  • Bmoney Aug 19, 2007

    haha, slug of liquor taken. I think im going to take it all down to the computer shop down the street and have them test each component individualy, hopefully that won't cost me to much money (they are a ma and pa computer shop). Then when I find the messed up one, its RMA time, and hopefully a quick replacement. preparing next shot...

    mbern I don't think -- is an error code, i bet that means all is that case it seems a lot more likely to be a video card problem since the motherboard is chiming in as good to go...hopefully you figure it out. good luck!


  • Bmoney Aug 21, 2007

    so I got a reply from Foxconn after a long winded message this is the entire reply I got:

    Try another brand of memory.

    wow thanks foxconn way to go in depth on your reply...maybe a suggestion or list of compatible memory? either way, i think the mobo's busted and I just RMA'd it to newegg and sent it out today...well try again, and if i get the same problem then its another brand of memory for me! thanks for trying guys.

  • Bmoney Aug 21, 2007

    well im glad I know now, it got pretty good reviews on newegg so I thought I would give it a go. Asus has always treated me right, but this one kept pulling me back in, and the good reviews convinced me. Well I will get the next one soon (same board) and hopefully I will have better luck. (I already sent for a replacement, so I cant get a different board now). Ill update later...

    I Shipped my computer to portland from alaska, when I pulled the beast out of its cardboard cave to plug it in and waste some newbs via the Interweb, the beast remained unconcious. Unfortunately there was no monitor signal. I resocketed everything in the computer and also replaced my video card with a known to be functional one, still nothing. the Debug code led is black, it is powered but it is not giving me a code. I bought another M/B just like the one I started with and I have the same problem. The powersupply seems to be cranking everything up just fine. Is it possible that the CPU is somehow toasted by shipping mishandling? Or is the issue in fact the Powersupply.

I alredy tried another brand of memory, didn't POST either. I am thinking about getting a new video card and if not that, then maybe both my mobo and the one that I bought are DOA. In that case, i will get a different mobo again. any thoughts? M

I'm going to assume you supplied the proper 8pin 12v connector besides the necessary 24pin, right? Unplug all cables to any internal peripherals, even data cables. Since you're getting random LED errors, I would remove the video card, open up one of those ancient computers to remove a PCI video card, install it on this board and boot to CMOS. I'd also prepare a Memtest86+ boot diskette and check each memory stick individually (that is if you have a PCI video card output). Keep monitoring/logging those LED errors (to note any type of pattern). The onboard MOLEX power connector, used to provide additional power to the PCI-Express slots when using x16 cards in SLI mode, is located between PCI slot 2 and the board's edge, as a last ditch effort, try powering it up when the Single SLI card is installed. Otherwise, you have either a mal-performing power supply (regardless the total wattage), a funky video card or a DOA motherboard. Always need to carry a known good PCI video card, I use a Matrox Millenium. OH... and take a good slug of your favorite liquor. ZT3000 "Beta tester of "0"s and "1's"

    You had good quality memory, but I didn't want to say anything about the motherboard.

    Foxconn is not a real good board, I finally broke down recently and bought two of them and both of them cause me hours of new build aggravation.
    I'd never sell them and I build and install computers in small business networks. I can't afford budget motherboards.

Mainboard error for install to win7 finalliting install

Hello the mainboards homepage is here:

From here you can download a manual.
You need at least 1gb of ram to install windows
And min.1,6 ghz cpu.
Is the windows disk an original or a copy ???
If a copy it may have be burned too fast.
Burn it not more than 4x or it will skip some files
and not be able to finalise the installation
I could also be the dvd drive.

Try also to enter the bios and set it back to factory settings
remember to set up the boot option again.
You also need a sata harddrive.
An IDE drive is too slow.

First boot device dvd
And second the harddrive

Good luck

Foxconn 945G7MA-8EKRS2 Motherboard will not post with pentium d cpu ,i have even updated with the lates bios flash,

Good day,
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
4BFF1P56 No Version 4BFF1P40
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.

My new video card Sapphire HD5770 is installed and now my pc will not post or boot, what can i do?

Make sure you have your card installed correctly in your PCIe slot, it should hook in. You also have to hook up power supply. This card requires minimum 450 watt power supply and 600 watt power supply if using crossfire and dual mode. If your system meets these requirements, and you have card seated properly and hooked to power supply. You may have to enter your bios and dedicate the PCIe slot. I'm guessing the system will boot without card.

Cannot format a sata drive completely, i have installed a new master hdd which is 500GB, however when formatting I can only see 128GB

Check drive for partitions. Also, you can use a program such as Seagate DiskWizard to format and setup for loading. That program is available from Seagate's web site.

I have 192mb onboad video memory how do i up grade to at least 256mb on board video memory

On board video memory cannot be upgraded, since it is on board. However, you can upgrade your video by buying a 256mb video card and have it installed. When buying, ask your supplier for the software driver installer CD, In this manner, you can immediately install this driver to your PC and get it working immediately. But, remember this, you have to disable the on board video through the Device Manager, under the Systems at the Control Panel. To activate your new video card, Use the Add Hardware at the Control Panel.


Alienware c51xem2aa out the box wont turn on

If there was a spark and it smelled, something probably burned through. If I were you, I'd send it back to Alienware and request a new one. Even if you could fix this now, the risk of it breaking again in the future is much bigger. I hope you'll get your new PC fast, Yannick.

Repeated boot

I supposed you are using windows xp, put the Win XP cd in your cd drive and start your computer

boot on the cd drive, wait until the winxp finishes its copying

When asked if your want to install winxp or repair [R] choose repair by pressing R

wait till the command line and type: chkdsk /r

wiat until it finishes, it may take about 20 to 30 minutes..

reboot your pc

Startup fault

Software Error Or Corrupted windows File files

No boot up or bios or image after installing the new mother board, Mr Bogdan

Brand new board? Unlikely to have a problem. Are you sure you connected the small 4 pin power supply connector to the motherboard as well? (besides the main supply connector)

If you have any IDE drives make sure you have not reversed the orientation of the cable.
