Read this, which I posted several months ago....I too, kept reading ALL OVER THE INTERNET about his being a VIDEO problem. ASUS technical support informed me that it's a MEMORY problem, NOT video. At least with THEIR motherboards, anyway.

>> Re: 1 long beep, 2 short beeps. i need HELP!! with mobo
I contacted ASUS technical support. It's a MEMORY issue, NOT a video issue. I tried 4 different video cards. Coincidentally, I ALSO have G-Skill memory. This was causing my problem. I had 2 bad sticks of G-skill memory. Got it exchanged from NewEgg, and it STILL doesn't run at 1066, but I have to manually change the clock speed of the memory to 800 to get it to run stable, but at least NOW it runs stable at 800 with 8 GB of ram.

Try using different memory sticks, 1 at a time to isolate which is the bad one.

I changed my memory timings in the BIOS to 800, instead of 1066, and the memory voltage to 2.08. I can now leave mine on for days with NO lock-ups, BSD's or shut downs.

I went berzerk for 3 months, not being able to diagnose the problem. Consequentially, I also think that the 2nd motherboard I had was bad. It took a 3rd motherboard, and 2 different sticks of memory to solve the problem-partially, then the memory settings in the BIOS.....It's FINALLY operating stable now.

My system:

ASUS M3N78 pro
AMD Phenom 9950 Quad-Core CPU
G-skill F2-8500CL5D=4GBPK 8 GB-total
NVidia FX7300GT
Seagate ST3750640AS 750 GB X 2

i have the same problem with my old laptop, IBM ThinkPad, it produces 1 long beep and 2 short beeps before it boots, it is more complicated than the desktop i think. Help..

I believe that EACH vendor has it's own specific code. You can probably write to Lenovo tech support (since they bought out the IBM label) and ask them. That's how I finally diagnosed MY Asus problem was thorugh Asus tech support. EVERYONE kept saying VIDEO error-all over the internet, but MINE was a memory issue.

I don't have any experience with the new Lenovo's, but the OLD IBM thinkpads were the industry workhorses. I'm currently writing this on my T-30 Thinkpad.
It's about 6 or 7 years old, but still works flawlessly. I bought a new Acer laptop, which is also great with a beautiful screen and graphics, but this T-30 keeps plugging away. It's still relatively fast, too.
The Lenovo's do NOT seem to be as prevalent as the OLD IBM thinkpads.
I guess more and more companies are going with Dell and HP.

Again, contact Lenovo's tech support for specific help on your model's issue. I'll bet they get it resolved for you.

Ok! So i have one for you. Long beep, 2 short beeps issue, buuuut.. Windows still loads, I can hear it in the background, I switched all my ram out 2 dif slots to see if there was a memory issue, now my comp wont even attempt to boot if it does not have 1gig of ram. I have x2 2gig ram cards, tried them all in dif slots and there all working, can hear windows in the background, takes a while to find my log in button without the screen but meh. So my ram must work, so could mine actually be a graphics card problem? I dont know how many times I have re-sinked it and nothing, well it came back once randomly and then went again later that night. So any clues?

I would say that in YOUR situation, it does indeed incicate a video problem.
I think that in MOST cases, it probably is, but NOT with the ASUS motherboards.
I will NEVER buy ASUS again.. I've read on forums that most high-end gamer PC's use ASUS MB's.... However, I had a defective ASUS DVD burner, and went through 3 to get one that works. I have bought a lot of merchandise from Newegg in the last couple of years, and 3/4 of it has had to be returned for defective. I've kind of had it with Newegg and decided to start ordering from ZipZoomFly instead.

If I was to mention its an ASUS mobo, would that change your mind? >.>
I dont wanna buy a new computer, I just wanna fix the one I have, but atm I really dont feel like shelling out loads of cash on hardware like a decent g/card to find out I needed new mem all along
