sorry to be a dope terry, but i'm not sure what you mean when you say "try
giving the card its own power supply"

the card plugs right into the mobo and draws power that way... not by
sharing a 4-pin connector like what plugs into a hard drive

i must be missing something

this is of interest to me since i am having the EXACT same problem but with
different specs (see the thread subject "geforce fx 5200 on athlon 900"):

PNY Verto GeForce FX 5200 128meg (non-ultra)
Abit KT7 (latest bios and latest VIA 4-in-1)
Athlon Thunderstruck 900
512 PC133
2 NICS (realtek & netgear)
SB PCI 512
Antec 300 W PSU
Windows XP Pro, SP1

i also play different games...

om...
I have had a Gainward Ultra/760 XP (FX5600 ultra) for 3 weeks and have
been unable to run 3D games for more than about 15 minutes without the
PC freezing and having to be turned off and on. I upgraded from a
Geforce 2 which ran everything without problems. The games I play are
Everquest and UT2003 and the problem also arises in 3Dmark03. The
freeze almost always happens when a new level/zone is loading or has
just loaded and very rarely in the middle of a level.

I have:

Athlon 2500
MSI KT4VL motherboard
512 Mb Corsair PC2700 RAM
SB Live
US Robotics network card
Thermaltake 420W PSU
Windows 98SE

These are some of the many things I have tried:

Upgrading to 44.03 drivers
Upgrading to 448 4 in 1 drivers
Upgrading to DirectX 9.0b
Ensuring that video, network and sound cards are not sharing IRQs
Changed AGP aperture from 128 to 64 and 32
Disabled/enabled fast writes
Lowered hardware acceleration
Increased AGP voltage
Underclocked/overclocked video card
Removed sound and network cards

I assume my PSU is good enough and I don't think it can be
overheating.
I also tried the card in another lower-spec PC and had exactly the
same problems.
My final option is to return the card - but I don't know whether it is
a problem with this particular card or if there is some compatability
with my system.

Has anyone got any ideas please?

Thanks in advance



hi.

a bit late if u sent the card back, but i had similar problem with my
fx5900, 400 watt pwr and volcano 7+.

I had to re-route all power connectors and make sure that the fx card was
only sharing with other low drain items, in my case just the volcano 7 and
a
twin intake fan unit. when i used power splitters from the hd to power th
fx
card it would randomly lock up and never complete 3dmark 2003. now it
works
fine and gives a 3dmark of 4934 with an xp2100 - try giving the card its
own
power supply and see if it cures your problem
