Question about Computers & Internet

Abit nf7-s rev2 not posting. Cleared CMOS, pulled out battery for 20 minutes & replaced, checked wiring and memory seating, checked graphics card and CPU in a different board and they worked ok. Im getting one short beep to say board is ok but a blank screen. Screen is ok just not receiving a signal. I bought the board off ebay so I dont know if previous owner tried to flash the bios and failed. Any advice wil be greatly appreciated, Thanks Mike

    Hi, Thanks for the reply.
    I tried initially with one stick of corsair cmx512-3200 which I thought was ok, but I got the repeated long beeps denoting memory failure. I then tried with a stick of Samsung pc 2700 borrowed from a friend, and got the short single beep denoting all was ok, but no signal was being sent to the monitor. This obviously prevents me getting into the bios to do any adjustments. I have bought some more Corsair memory which I will try, but I am beginning to think that it is a duff board.

Have you tried replacing the memory modules? Memory incompatability or a bad simm, will create the symptoms, you describe. Also, restore the BIOS settings to "fail-safe," if possible. Often the "Default settings," are not as "tolerant," as fail-safe. I had a similar issue with ASUS and LanParty motherboards. It was a bad SIMM.

    The only two things, left, I can think of would be:

    1) Whomever you bought the motherboard from wiped the BIOS and blew it. I checked multiple boards and there are instances of the BIOS' getting flashed and no longer functioning. You COULD try a new BIOS (from ABIT).

    2) There is a known issue that after flashing the BIOS it reverts to "old 100MHz FSB settings." This has been an issue with this particular MB and if you have an old processor (equal to or less than 100Mhz FSB) I would try plugging it in and seeing if you can get to the BIOS, from there and update.

    I found instructions on how to flash the BIOS (correctly) It is not as simple as others.

    It IS possible that your MB is nonfunctional, but I do not think so.

Won't boot up


First of all make the memory is seated properly and that the motherboard supports the clock speed of it, i.e 400-800 MHz.

Then make sure that the processor is seated properly, take the processor out and put it back in.

Next if you are using a AGP graphics card and not any on-board graphics make sure the card is seated properly in the slot. A good idea to test the system is to use the on-board graphics port first.

Also clear the CMOS with the jumper that should next to the motherboard battery. If there is no jumper there remove the lead from the back of the unit and then take the motherboard battery out for around 20 minutes periodically hittting the on/off button to drain any residual power from the motherboard.

After 20 minutes are up put the battery back in and power the machine up.

Good luck and please post back if you need anymore help.

Did you make sure to install the memory starting from DIMM3? You should install into DIMM3 then DIMM2 according to the NF7 manual.

Abit kr7a-133r morherboard will not post At first, it would not post every now and then. I would need to turn off and on 2 or 3 times,and then it would run fine. after a couple of months it got worse, I...

I take it you have the same type of memory[matched in pairs]. I had an asus board that did the same thing. I started the way most builders do when they bench test, I sarted with just 1 memory stick, l [left 1 rom in] and removed everything I could. With the Dell that started to act up I cleared the CMOS over night with the jumper in the clear setting. I was able to get the Dell to work, I ended up selling the Asus board and the guy who bought it said he cleared CMOS and replaced the battery and it fired right up. My first Abit board[NF7-S] came with no manual or drivers disc. It's used but one thing I can say is Abit really didn't look like it's site was much help. I am just about to test it. It does sound like a device problem. You can go online, if you updated your BIOS it may cause problems but I'd also look at the updated BIOS to see if there is a update with this problem listed. One last thing, if you have extra cables try them to see if it is the hdd cable, thats happened to me also.

Abit NF7-S Nvidia2 Failed to Boot

Try swapping the power supply and as Nitro says also check the cable and connector from the power switch to the mainboard.

Post code 9.0.

9.0 Complete uGuru initial process AWARD BIOS take over booting job.
9.9 Complete power off sequence.
Did some reading & it's not good. Some say it's the memory most point to the board being bad. According to the posts resetting the bios jumpers will not let you enter the bios either.
You can test you memory in another machine but again most posts say their memory was just fine. No one said it was the CPU. If you want to download your manual click the link below.
