GA-7N400 Pro2 apparently dead with DRAM error

[AvidTwo]

I have an old system using a GA-7N400 Pro2 motherboard (Athlon XP2500+ CPU) with a lot of important legacy software installed on it. It's been working fine for more than 8 years, still used regularly, and the configuration hasn't been touched for a couple of years. A few days ago it suddenly froze in the middle of running a program, and on reboot it just beeps and the screen remains blank. The POST beep pattern is a repeating series of long beeps, which the manual says means "DRAM error". I tried re-seating the DRAM strips, and then I tried each of the DRAM strips alone in each of the 4 slots, and then I tried swapping the DDR2 DRAM strips with another old system. No good, same beep codes. Then I unplugged all the peripherals from the motherboard and tried again. No good, same beep code. Then I swapped the power supply for a alternate one. No good, same beep code.

At this point I assume that something on the motherboard has failed invisibly and permanently. I've examined it carefully, and there's no sign of leaking or bulging capacitors or any other visible fault. All the fans still spin, including CPU and Northbridge fans. I assume that the CPU is working since I'm getting a POST beep code. But at this point I can't think of anything else to try.

Any ideas? Has anyone seen this type of fault masquerading as a "DRAM error" on these old motherboards and discovered a different cause?

Good timing for Gigabyte though - I just bought a new Gigabyte motherboard because my old one was reliable! One more week and I might have been looking for an alternative more reliable brand instead.

You gigabyte lasted 8 years and yet you say at the end you might of looked at a different brand if you hadnt already bought another gigabyte. I have had asus last 3 years and a dfi that lasted 18 months id say you were doing good at 8 years.  Had that same error i found my slots went dead couldnt tell you if it was the slots or the northbridge chipset.

Mine at that point was a little over 3 years old and when it happened i figured it was time to upgrade anyway. Things dont last forever and after 8 years i would say you had a real good run of luck to last that long.

No luck, the board turned out to be permanently dead. No visible sign of any fault after it was removed and stripped.

I don't agree that one shouldn't expect a motherboard to last more than 3 years, or 8 years. This is the first and only motherboard I've ever had fail out of dozens, and it failed spontaneously while in routine operation in a stable system with good cooling and no overclocking. That shouldn't happen. I don't have any statistics on how often it happens to Gigabyte motherboards, or to this particular model, so I can only go by my own personal experience: Gigabyte: 1 failure, all others: no failures.

In a little over 4 years or so i had 2 bad asus with rma nightmares and one msi that went bad. I have had 1 gigabyte with 2 of 4 ram slots go bad after 18 months. Now in perpestive I have built 400 or so systems in the last 12 years and the asus boards had the highest failure rate.

I am also not a Gigabyte fan boy just found that dealing with other rmas that gigabyte was the easiest they cross shipped me a new motherboard for the one with 2 dead ram slots all others brands i had to send in and wait for the return which to my customers wasnt a good deal so i always kept a few spares on hand.

My board nowe is revison 1 of the 890 chipset couple years old overclocked a bit and no problems. Grass is always greener on the other side until your actually on the other side i guess.
