My problem is running 3D games or 3D screen savers it just freezes or the
monitor screen goes black, I have tried different resolutions and refresh
rates, I e-mailed ATI I have tried all the fixes they suggested, All drivers
are up to date including bios, he suggested change the agp voltage, it
seemed to make it last longer before it froze but it still did. Has anyone
ever had this problem, also I installed my old g-gorce 3 ti500 and it never
froze up also yes I am over clocked 10% but I set it back and it still did
not help, maybe its a bad card? Any help would be greatly appreciated...
also I tried disabling the on board sound but that didn't help...

You did not mention power supply. A good quality 350W supply is a must.

Be sure your RAM is good by testing with Memtest86.

3D games use %100 prossessor power so CPU gets much hotter than when idle.
Be sure CPU temperature is good (less than 60 C) under full load by use of
motherboard monitoring program from MB manufacturer. You may have to
increase CPU Voltage if overclocked.

You mentioned overclocking CPU, be sure the AGP bus is not overclocked.
Check frequency dividers to find AGP frequency. Should be 66 MHz.

Check the forums at rage3d.com

Please post back when fix is found.

Ok, now this sounds exactly like the issues a lot of people are getting with
the new 865/875 chipsets (myself included). To cut a long story short, it
seems that some motherboards undervolt the CPU, RAM or AGP (often all 3)
which causes some pretty inpressive instability. I have 2 865 systems (an
Abit IS7 system, and a Shuttle SB61G2 SFF pc) and both required a good boost
on the voltages to get stable. My IS7 needs 1.575V on the CPU, 1.6V on the
AGP and 2.7V on the RAM to ensure it is properly stable and the Shuttle
system is about the same. They are also very picky about the timings
selected for the RAM and often incorrectly detect the timings if you let the
motherboard decide for itself. Try relaxing the RAM timings in advanced
chipset options and upping the voltages to the values above and see if that
helps. Certainly run the system at stock speeds while doing this - you need
to eliminate as many possible causes as possible. Let us know if it solves
it,

Well I think I got it fixed, 1 hr running motogp 2, 2 hrs Medal of honor
spearhead, and 1hr running watermill screensaver(it usaully locked up after
3or 4 min) well so far so good. I changed the AGP voltage from 1.5 to 1.6,
disabled fastwrites and last but not least I installed the biggest fricken
VGA heatsink I could find, so far so good.If I have any probs I'll post
again, ATI should address this on there website I have seen alot of post on
many forums about this same problem. I dont think the "stock" ATI cooling
and heatsink are enough.
