View Full Version : System lockups running any 3d related app.
06-24-2005, 09:01 PM
Just bought a new 6600GT card which is great and i love it but unfortunately havent been able to use it much. Every time i run a 3d related app be it games/Maya/XSI/Max..it will lockup my system and sometimes auto reboot (most of the times i have to do a hard boot). I also tried swapping the nvidia for a brand new ATI 9800 pro to see if my card was bad...but no joy.This happens with the ATI card as well. I have a Tyan Tiger K8W S2875 Opteron 248 dual procs with 2 gigs of RAM and a zippy 460W psu running WinXp pro on a 160 gig SATA hd.
I installed old nvidia drivers and it actually ran 3dMark and Aquamark. However about 5 minutes into a game and the system locked up.With the latest nvidia drivers i wasnt able to run even the 3d benchmark apps, let alone any games.
I have the latest AMD drivers/BIOS/etc etc and have also tried doing a clean XP install on another HD with no results.
Another example..while drawing a render region in XSI..the system locked up again and rebooted.Im not getting any BSOD and absolutely no indication as to what is causing this.
Has anybody had these issues before? Please help.Thanks.

Sounds like the power pack doesn't provide enough power or it is simply too hot.

I have tried changing the power supply to a brand new 460W Zippy and it still wont do anything.So power supply isnt the problem here. What baffles me is that my older VGA card such as the GeForce 4600 will work fine but the new ones wont. I am going to try memtest today to see if i have faulty RAM.

If you really want the BSOD you should have a setting somewhere in BIOS for "shutdown on error".
Is anything reported in the event viewer?

Right-click on My Computer => Properties (or hit Windows Key + Break)
Click the "Settings" button down the bottom
Turn off "Automatically Restart" under System Failure
At least you'll get a chance to look at any error messages rather than it rebooting.

Tried doing a memtest and it runs out fine.No issues. Bought another PSU to test it, nothing happened same old story.Also its not logging any errors in the winxp event log :(

The 9800pro and 6600gt both require additional power via a molex connector wheras the GeForce 4600 draws its power from the AGP slot.
I'd suggest that the extra power required by the 9800pro/6600gt when your system is running games/3D apps is a likely cause of the failures and a more powerful power supply (550W+) may help. It's also worth checking that the molex connector to the graphic card isn't also powering any other devices as this could affect the stability of the supply to the graphic card.

thx for your input andy. Yea i think i should try a 550W PSU although i still think its overkill for these cards. Its strange when my BIOS doesnt show a +12v line reading, it only shows -12v but when i check it with SpeedFan the +12v line shows 10V. Also i checked the event log and it gave me a lot of repeated errors.
The COM+ Event System detected a bad return code during its internal processing. HRESULT was C0000005 from line 44 of d:\qxp_slp\com\com1x\src\events\tier1\eventsystemobj.cpp.
I have no idea what this means.WIll try and google it up.
Thats a very strange problem.. perhaps you should inspect your motherboard for problems just to be sure. Like bloated or leaking capacitors, damage around the main power plug, etc. If all looks good, give the system a good dusting, just to be sure that dust isnt your culprit (I've seen strange things happen).
