computer freeze ups

[afilis]

I have put together a system:

Coolermaster elite 330 (two 120mm fans)
Asus M2N8-VMX
amd64 3800+ power saving
2gb DDR2-800 elixir M2Y1G64TU8HB0B-25C
seagate 7200.9 barracuda 80gb
winxp pro

There is no overclocking.

When i put the system together it will not post with both ram sticks, it will post only with one. After a bios update to the latest the system will post with both sticks. Both sticks are sitting on the same colour slots.

The system is running 24/7 without screen, keyboard, mouse or dvd/cd drive, is networked via a speedtouch 780wl on the intranet and internet.
I manage the pc via ultra vnc, via internet or lan.

The problem is that every now and then randomly i'm losing the pc and i cannot connect. When i connect a screen on it, this is what i see.

Sometimes it does that a few minutes after bootting into windows or after days.

It is not happening very often like once a day...but is still there.

On the bios i have increased the vram shared memory from 124 to 256mb.

My gut feeling is that it a hardware and not software issue and more specific a memory problem.

I have run memtest86+ for a couple of hours and prime95 for same or more time with no errors...

Also temperatures of cpu are 29 idle and no more than 50 load...system is running pretty cool...

I have also changed PSU's but is happening in both cases.

Any ideas?

Probably no real help here, but I didn't see what your Video card was. Different drivers may help the display portion.

The freezing issues sound like it could be a resource (IRQ) conflict problem. Is there a Soundcard or other PCI cards in the System?
I've seen lots of issues with Soundcards causing the problem you describe. This can usually be fixed by moving your card to a different PCI slot.

Your temps look a bit odd to me. Currently the ambient air temps here have been around 85F, and my System generally idles in the upper 30's C and maybe 47 at load. It may be nothing, but with your idle temp so low I wouldn't expect it to go up to 50. You may want to redo the Heatsink and Thermal paste.

thanks for your reply...

the mobo has an intergraded 6100nvidia chipset and i have not extra pci slots...so is just the mobo, cpu and memory....nothing else attached...

temps seem reasonable to me...since it scales up when the system under load...and pretty cool idle....if i'm not mistaken amd are running cool idle?

Have you turned off all Screen Savers and disabled Power Options?

i have turned off the screen saver...but on the power option is set at minimal...so the cool and quie feature will work effectively...

ok this problem really freaks me out now...i'm still getting freeze ups...which they are actually freeze ups on windows...
mouse will be moving..and then after seconds nothing will be moving...only thing i can do is hard reboot...

Since then i have:

bought another mobo MSI K9N6SGM-V, it has the nvidia mcp61v chipset with onboard graphics (6100).

I'm still getting the same problem.

On the old asus mobo and the new one i have plugged the DDR2 memory that I'm using on my gaming pc (c2d, 965p-ds3). Both set of memory result the same freeze ups. I have plugged in the elixir memory on my intel gaming pc and it works perfect with no freeze ups after many hours of heavy gaming...
Also, i have changed the PSU from 300w to 450W.
So to recap:

Mobos: Asus M2N8-VMX with 6100/405 chipset, MSI K9N6SGM-V with mcp61v chipset. I believe that are similar chipset if not the same
Ram: 2gb DDR2-800 elixir M2Y1G64TU8HB0B-25C, http://www.microdirect.co.uk/(.....y-M2Y1G64TU8HB0.aspx

2gb DDR2 Geil Ultra DDR2 800
http://www.microdirect.co.uk/(.....00-Dual-Channel.aspx
http://www.geilusa.com/products/show/id/65

So both sets of memory are working perfectly normal with my intel cpu setup.

Somehow the nvidia chipsets do not like these sets? Is it something else i should be looking at?

I have changed PSU with no results. I have only one hdd plugged, sata2 80gb.

All my pcs are setup exactly the same way with the same patches and software.

Are there any reports of these nvidia chipsets with onboard video being picky on their memory?

Not so sure but i'm pretty convinced it's memory issue.

How did it turn out ?
