Question about Jetway 939GT4-SLI-G Motherboard
I just transfered an AMD CPU, 2 gb RAM, and eVGA GeForce 8600GTS (256mb) video card onto my new Jetway 939GT4-SLI-G mobo.
Everything was working fine in the old setup, but the Jetway won't POST. There's no video on my monitor, and the debug code says 7F, which roughly translates to "POST error, see monitor for possible fixes." I cannot do that due to my lack of monitor output. Is there a way to save this?
Try cleaning the memory teminal with soft paper eraser.

Ok, other people have noted that sli slots come in 3, but sli requires two video cards to operate.
apparently, by shoving a card into one of these two "outer" sli slots the system bios automaticly starts SLI mode. and no matter what you do, you won't get video. unless of course you have SLI video cards and you have them in the appropriate slot.
The solution is simple.
yank all the video cards.. or 1. whatever. yank em all.
next. set the jumper to clear the bios, it's labeled "JBATT" and the instructions tell you "JBATT 2/3 clear cmos, and 1/2 for regular operation" or something like that.
Clear the bios.
once you boot it, while it's in "Clear cmos" mode, let it stay on for like 10 seconds and go to FF on the display.
shut it down and remove power or flip the switch on your power supply to totally shut off power to the system.
Change the jumper back to 1/2 for normal operation.
Place your card in the MIDDLE SLOT that's marked "single operation"
or if you have SLI, place them in slot 1 and 3 and connect them.
Boot the system with video cables attached, and everything will now boot as if you just initally purchased this motherboard, due to the bios being completly reset. even your time date will be reset.
This worked perfectly for me.
I will never buy jetway ever!!

Ok this from guest posted on July 11,2008 Not sure this will help anyone,but it seems to have "fixed" my problem.
1. I did all the normal(reseated cpu,took all ram out, cmos battery,re-set jumpers,disconnected hard drives(sata's) got nothing.
2.Put memory one stick at a time,into different memory slot.(got post with one stick in third slot).
3. Last thing that seems to gotten system to POST. Took out video cards.(remember I was running SLI. this board has three PCIe slots(middle one for single) oposite for Sli) like slot 1 and 3 for SLI. slot 2 for single card. WELL WHEN I MOVE ONE CARD INTO SLOT 2 SYSTEM POSTED AND THEN FINISHED BOOTING!! I feel in is the PCIe slots that are causing problem.
So if you only have one card. try placing that card in each slot. then into middle slot. it may clear SLI path allowing video signal too process. Sounds crazy but it worked for me. Or the God's of motherboard failures smiled on me this time.

Do you see a bios screen at all or you just dont receive a signal at all?
