Graphics Turns PC Off

I just put together a system for desktop use:

Asus A7N8X-VM (nForce2 IGP)
Athlon XP 2600+
512mb TwinMos DDR3200 (2x256, 32mb to graphics)
WD 80GB SE 8mb 7200rpm

The system when under full load runs at around 50-52 degrees. (Tested by running D2OL)

The problem is whenever things get graphical. I tried to run 3DMark2001SE on the computer and it just straight away restarts. I have the latest unified driver from nVidia installed on the system (i'm using the onboard graphics for this system).

Does anyone have any ideas what's going on?

*Edit* The PC is running WinXP Pro SP1
 
Have you installed the motherboard drivers as well (nForce chipset, not Forceware?) All the updates from Windows Update as well?

Also, bump up that graphics share to 64MB, or maybe even 128MB.

Dang, I was hoping to not be trying to bump it up, will have to wait to try that in the morning, need to get the monitor to try that one. Been working off VNC. I have the motherboard drivers installed. Ain't got to the windows update yet. Will see.
 
This seems to have developed, it is now doing it anytime it feels like it really. If I start doing a few things it just restarts for no apparent reason.
 
Check your RAM with memtest. Also check to ensure your PSU is providing adequate power. Both these things can cause random crashes and restarts.

Yeah, what power supply are you using (brand & model)? Also check Event Viewer for clues (if it happened to be a Windows issue) and if it were a motherboard where it were even possible, I'd suggest forcing the RAM to run in sync with the CPU's FSB and bumping the voltage to 2.6V. If you have some PC2700, use that.
 
I had a look in even viewer, and right about the times it restarts, I see a bugcheck. This seems to be causing a memory dump or something?
 
K, try disabling the automatic-reboot-on-error thing in WinXP. Can anyone help him find it, I'm not an XP user.

What's causing the bugcheck is the question. Is your PSU a respected brand-name one? Got any PC2700 you can try?

Winkey+Pause
Advanced tab
"Startup and Recovery" section - "Settings" button
Under "System Failure" uncheck "Automatically restart"

Have pad and pencil ready. 😛

I'm also confused as to what your monitor has to do with the amount of RAM allocated for share.

:light:
:Q

nF2 boards will only run at 266 or 333 DDR memory speeds with onboard graphics enabled. Doing otherwise will cause your IGP to throw a huge fit. Make sure you've got the memory at DDR333!

Asus spat out an A7N8X-VM/400 that can handle 400MHz-bus CPUs too, although he didn't say that his was the /400 variant. What's unfortunate is that neither the A7N8X-VM nor the A7N8X-VM/400 have any provisions in the BIOS for changing memory timing/voltage (or if they do, they don't show them in the manuals) 🙁 That's a bummer since the full-ATX versions are all tweakable.
 
Hmmmm...

I just bought a refurb Asus A7N8X Deluxe ver. 2, and my computer is doing the EXACT same thing.... I think it's the mobo being defective, as my PSU is an Antec 300W that's been working in another computer for a year just fine, and my RAM is PC2700 Crucial, two sticks of 512 MB...

Is Asus having quality control issues in a major way? A friend that is an IBM retiree builds computers as a sideline and he just went through FIVE A7N8X Deluxes...all of them had power related issues...

Wish I could help you more...as I need the same help...but just thought you may want to know that it could be the motherboard itself.

I'm really hoping it's not because the build is for a friend and I advised him to upgrade and go for this board instead of an EPOX (although the EPOX was a VIA chipset).
 
That thing to change the Automatically Restart made no difference. I'm going to try an actal graphics card in it and see if i can get it working.
 
I stuck an old nVidia TNT2 M64 graphics card that I had lying around and now it runs 3DMark2001SE without a problem (apart from the incredibly poor performance). Thankfully the person the system is for isn't terribly interested in gaming so I think I might get away with this card in the computer.
 
I just always known ASUS as a good make. Have they gone to the dogs as far as reliablity goes? Think I might be able to get this pc stable enough to pass on for simple desktop.
 
Well my K8T800 Asus has been stable. Even though they did release a small batch of motherboards that had leaky capacitors.

I had a simliar problem whenthe geforce 256 came out. As soon as I ran any type of 3D the system rebooted. I bought a larger power supply and it solved my problem.
 
It's a Q-TEK 350Watt power supply. I thought it would be more than enough. It is running 2 CD Drives and one 80gig WD Caviar. There is only a modem connected to the mobo and a whisper 2500rpm fan (TNT2 when not using onboard).

Sadly the largest PSU I have lying around is 350W.

When it comes to PSUs, quality is important, not just wattage. What brands are your other PSUs?
 
Since the graphics card works, you isolated to onboard graphics. Try flashing bios to latest, change the graphics drivers, change some of the graphics chip settings in bios, reduce directx accelleration, check directx diagnostics (dxdiag.exe), change refresh rates for 3d or different resolutions, etc.
