I would like to invite everybody to diagnose my computer error for me. I got the following configuration:
- Motherboard: Intel DG33BU ( 3 years )
- RAM: A-DATA 1GB DDR2 667MHz x 2 ( 3 years )
- CPU: Intel C2D E6400 ( 3 years )
- HDD: Seagate 1TB Barracuda 7200RPM SATA II (bought 1 week ago)
Checking the RAM
The motherboard suddenly sounds 3 long beeps when I switched on my computer this morning. I looked into the documentation and the mighty Google. All redirects me to memory error. To prove my RAM is not faulty, I put it on another known working desktop (with different configurations, of course), the RAM works without problem. Also, I have inserted another pair of Kingston DDR2 533MHz RAM (2 x 1GB, dual channel) into the motherboard. The 3 beeps persist. The culprit is not the RAM.
Checking the CMOS battery
Okay, I moved on to next guy found in Google. He said it might be CMOS battery fault. He tried to remove the battery and do a power cycle. I tried the same. No use. The culprit is not the CMOS battery either.
So, what is the problem? I know the motherboard is old ( 3 years ), but I believe in Intel's quality. Anyone else encounters similar case?
p.s. I don't have enough money to upgrade to i7+DDR3 (my next target)
UPDATE: the same 3 beeps sounded when no RAM is inserted. Obviously it is not about RAM error. Can I be certain that it is a motherboard failure?
