I've got an older home built system about 7 years old. I was experiencing random reboots and browser closures. I ran the Windows Memory Diagnostics. It failed the LRAND test almost consistently so I replaced the original 512 MB with a new 1 GB module. It still checks the same. I put the old 512 MB stick that I had removed in an old HP unit and ran the mem test on that. The memory checked out perfectly which leads me to believe that the memory wasn't the problem in the first place. So, am I correct in assuming that the mobo is the next most likely culprit?

I really am not too enthused about replacing the motherboard since that would probably call for a new processor, new memory, as well as a new graphics card. And I'd still be stuck with two IDE hard drives.

System specs:
ECS-Elitegroup L4S8A2 Motherboard
Pentium 4 2.4 Gz processor
1 GB DDR 333 RAM (PC2700)
ATI Radeon 7000 Series AGP Graphics adapter w/64 MB
30 GB and 160 GB IDE Hard drives

Thanks in advance for any help or advice.

do you have the latest bios?

check your version and mobo revision number?

check your bios memory speed settings

No. Try not. Do... or do not. There is no try.

You seem to have an excellent skill at detailed description, I googled your mobo, got to that link and downloaded your manual

The link also shows how to identify your motherboard and bios

The manual lists the settings in bios for the memory

A lot of people won't even open the case, fixing older computers is the first step towards building your own

I have the User's Guide for the motherboard in hand and nowhere does it mention the BIOS version. And yes, I too have visited the ECS site and located my motherboard. From what I gather, there are two BIOS updates available, 1.0b and 1.0c. But the site expressly asks that you not upgrade unless you need one of the fixes available.

So back to my original question. Is the mobo the suspect for failed memory tests when the memory checks good on another computer, or should I be looking somewhere else?

the motherboard is either failing, or bios is set wrong for the memory or your powersupply is too weak?

the memory should be good

death and taxes are for sure, the rest is guesswork, hopefully educated


on that web page is a link
M/B PCB version
you can make sure the page and bios listed are your motherboard

usually when your computer posts it shows the installed bios, sometimes even in bios itself

use the pausebreak key when it first boots

this is a good time to learn this stuff, you don't have as much as lose if you break it

ECS is a terrible brand of motherboard, a new one isn't worth the 40$ they sell for, an old one is more trouble than it's worth

SIW will show you what BIOS you have, its version and everything else that you would want to know.

Quote "the motherboard is either failing, or bios is set wrong for the memory or your powersupply is too weak?"

I've checked the power supply voltages and everything looks normal. I haven't made any changes to bios settings and have a really difficult time convincing myself that the box ran perfectly for over six years with the present settings, and suddenly they are wrong. So I guess that leaves the motherboard. I think I'll bite the bullet and rebuild the system from the case up. The only reason I really didn't want to do that is that this is now my wife's computer. About all she uses it for is e-mail and playing simple on-line games.

Thanks for the replies.

I've seen, on rare occasions, that defective memory slots/memory controller channels will give bad results in MemTest. The usual test is to try one of the known good RAM modules in each of the slots - this'll let you know which slot's are bad and which are good. If a known good RAM module fails in all slots, then it's a safe bet that the motherboard is bad.
