I have a new A7N266-VM board. When I have everything plugged in I power on and I get absolutly nothing. No beeps, nothing on the screen. I know I am getting power because all the fans turn on and the green light on the board lights up. The strange thing is when I remove one of my 2 128MB DIMMS then I do get the long continuous beeps that the manual says is supposed to mean missing memory. No matter which stick I remove from which slot I get the long beeps. I have checked and double checked what the board manual says is the frequency jumpers. I have tried underclocking the memory bus to 100Mhz. This is happening on 2 yes 2 identical machines I am building. I usually have no problems with ASUS products but on this one I am stuck.
1. Why is nothing happening when I boot with both sticks of ram?
2. Shouldn't I be able to at least boot with just 1 stick of ram?
I am using Crucial memory (part # CT1664Z265). Which is DDR PC2100, CL=2.5, Unbuffered, Non-parity, 2.5V, 16Meg x 64
Any help would be greatly appreciated. Thanks in advance.

Yes I have tried using just one stick in each slot. I did finally get it to get the error with both sticks in which I think is much better because it is more consistent. I tried one thing as well that another site suggested which was boot with just the RAM in and I got no errors. I am leaning toward a bad proc but what still troubles me is that this is actually happening in two identical machines which makes me think I am doing something wrong.
I can tell you one thing though. I was a hardcore ASUS fanatic until now. I can understand having hardware trouble but they have VERY little on their site about the A7N266 series. Even the manual that came with the board talks about jumpers that just don't exist! I tried to clear the CMOS but I have no clue what jumpers to move because the one they says does it which is right below the battery is just not there.
If any of you can find a remedy for the problem do let me know as I intend to buy one next month; the exact same board and if it is giving problems I should be looking elsewhere shouldn't I.I went totally head over heels when I checked out this boards specks and that too in a microatx form factor.I would be grateful if you could enlighten me on the functioning of this board.
The manual for this board is wrong!!! The clockspeed jumpers are exactly backwards from what it says in the manual. After I figured this out the board worked great but I burned out 4 different duron processors in the process.
Good luck for anyone else trying to use this board.
yeah, it's like the weirdest thing... luckily I saw the thing in the BIOS and switched the jumpers before it burnt through my Athlon. Are there like different versions of the a7n266-vm or is the manual just wrong? Coz my jumpers for CPU/RAM frequency is the opposite just like yours, I don't have a clear CMOS jumper, but the manual does, and I don't have a network jack like in the manual, but I it is enabled by default in the BIOS.
so how are your jumpers connected now? both on 1-2 or 2-3? i too am having big probs booting up...i power the system up it detects my athlon xp 1800 and memory size then powers down???? all in about 4 or five seconds after pressing the on switch. i cannot get as far as to see press del for bios setup.You are right there is no cmos jumper on my board either but the manual shows it just under the battery....???? what can i do ?? can anyone help?
I am having the same problem right now with a machine I built for my g/f. A7n266-VM with a 1.3ghz Duron, and i'm getting no video or post beeps.
It sound like i'll have to check the clock/dram speed jumpers, and might try the BIOS battery. There is nothing worse than a mboard manual all fscked up.
I put an A7N266-E in my box at home, and haven't had any problems at all, and other machines I built with Asus components have been amazingly reliable. If I have problems with the next board I get off of 'em, though, I might think twice the next time.
I'm having the exact same problem with my a7n266-vm. I have an athlon xp 1700+ in there with one 128mb ddr-266 dimm. I had the problem where the system would shut down after 3 or 4 seconds. I removed the cmos battery and put it back in. Then I could get into the bios screen. Then after 10 seconds or so the screen went blank and I haven't been able to get anything back on the screen. I tried taking the battery out again.. no luck. I tried changing the speed jumpers... nothing. Does anyone have any suggestion??
The problem I am experiencing is that I have the mentioned motherboard, 2x128MB DDRAM and a AMD Duron 1.3GHZ. I wasn't getting anything on the screen, it was staying in sleep mode, after playing with the jumper settings I started to get the long continuous beeps for bad memory. I have now got rid of this but can't get anything on the monitor still.
I have a Duron 1.3Ghz
2x 128MB DDRAM
Is it likely I've burnt out the processor playing with the settings or what? Can soemone please tell me if they have the same spec what they have set there jumpers to and it's working?
I'm experiencing the same problem
I have AMD athlon 1.33ghz, 300w power supply, samsung 512mb pc2100 ram when i turned the computer on, there was nothing on the screen
I waited bout 4 or 5mins, and still nothing on the screen
I checked the website, and they said the jumper setting on the board is wrong.. and I did what they suggested
but still nothing on the screen...oh also I tried AMD duron 800mhz, but same problem happened...nothing on the screen
can anyone help me please?
I have the A7N266-VM w/o LAN. I experienced the same problems I see people posting on this board. What the manual says for jumper settings are wrong. I don't know if you can go to their website to get the correct information or not. All I know is that the default settings are 133:133, but are in the opposite position than what the manual says.
Problem #1: When I first got the board, I tried it with 512 MB of DDR 2100 RAM and an AMD T-Bird 900 Mhz CPU. The documentation is vague on this, but it seemed that it would work - but nothing. No beep, just nothing.
I then installed the AMD XP1900 chip when it finally came, and it worked great.
Problem #2: However, I had XP OS on my hard drive, and it would boot fine, but when it came to loading the OS from the hard drive, the OS gave me a blue screen saying something about "windows detected an error and stopped the operation to prevent damage, press a key to reboot". Thanks windows! I then used the OS CD to re-install using the REPAIR option. Once that completed I was able to boot normally. All my data was there, but Windows updated drivers and settings for the new MOBO.
Problem #3: I have a Geforce3 Ti-200 card. It turns out that you have to use different drivers for the Geforce3 on the A7N266-VM MOBO. Download the nForce drivers from nvidia.com. It is important that you do NOT use the nForce drivers on the CD if you have your own Sound Card. If you do, your video card will work right, but your sound will be seriously messed up. I also disabled onboard sound settings in the BIOS. I used the normal sound drivers from Creative.com for my Sound Blaster Audigy and all is fine. I messed up my drivers before I realized all this, and decided to start with a clean slate and format and reinstall everything - things are smooth now. Remember, you have to use nForce drivers on this board.
Lastly, I used 3DMark 2001 from madonion.com to benchmark the system and make sure it was running good - I score close to 7000 - big improvement from my PC133 900Mhz system! I get over 166 frames per second on some of the tests.
All in all, this is a great board for an awesome price - but I would do a fresh install if I were you.
I love my new system. Battlefield 1942 runs amazing with all setting on High - and I have no lag in EQ with this system.
