1.3@1.45 crashing in games ONLY

[Aftershock]

Okay I know this is extreamly vague but if anyone could give me some ideas...

ThermoEngine Stock

Radeon 32 DDR

okay it doesn't happe too much, but when I play games, such as Tribes 2, Counter-Strike, Diablo 2 the comp will crash occasionaly. I get around 2 crashes per 4-5 hours of playing. Either my video card will stop giving signal, so my monitor clicks to a blank screen, and I can hear my sound card studdering. Or the screen will just freez. This happens after I've been playing consistantly for a while.

I can run Prime95, and the cpu stress tester that I grabbed off HArdOcp.
it can run for days rock solid.

I've tried uping the voltage to increase stababilty, didn't notice a difference, loowered my OC'ing down to stock 1.3 and it still crashes. Anyone have any ideas?

Chip'd CPU maybe? Temps too hot or just one of those Via mysteries..
My old P3 700 (Dell) was ROCK solid.

I have latest bios well the 4/26 and latest via 4 in 1
Just to add, I'm using a powerman 250w PSU, I know its crappy, but I'm waiting on my Enermax 350w whipser. I also have 2 HD's in raid 0 (IDE) so those may be taking up some juce also. I know T-birds require a little more juice than P3's but I'm not sure how much, I don't think the 250w could be the problem could it?

try the iWill faq at www.fullon3d.com
theres much info about gaming crashes there, hope it helps!

could it be the cause of a cracked cpu?

I've heard of cracked cpu's working, but performing rather flaky

it MAY be that your Radeon (lucky git) is overclocked too much.......maybe try lowering your FSB and raising the clock multiplier for your CPU.....maybe try none of them...who knows?....these MAY help ...or....have you done the old pencil trick on your CPU and maybe its rubbed off a bit?....i dunno......latest drivers, latest direct X, blah blah blah blah........you get the picture

My personal opinion is that you're running your CPU too warm. They run more stable the cooler you can get them. My 1.0G Tbird is much happier and overclocks to higher speeds the cooler I can keep it. I can be sitting here watching the digital thermometer as I am running 3D Mark 2001 and as soon as it hits a certain temperature, blammo it fails. I then have to reduce the speed to get further. Regardless of what anyone tells you, temperature is important and I don't just mean the 90C drop-dead one.

I was experiencing the same problem a few weeks back with my Ati Rage fury/pro/expert 2001 I put a small coolermaster fan on the heat sink of the Vid card and the problem went away. I robbed the fan off a crappyheat sink I got with a 750 T-bird last year. I also agree with Hoot you need to bring the temp of your cpu down Try replacing the stock 19cfm fan on that Thermoengine with a YS-Tech 27.5 cfm fan there not that loud and it will bring down the temp a substantial amount aiding in stability. The ThermoEngine is a good heat sink but the stock fan doesn't cut it. 3dfxcool has the Ys-Tech real resonable and they have a lifetime warranty . Also in a week or so they will have the 34cfm fans in, they will be a little louder than the YS-Tech but will provide additional cooling. I would recommend 3dfxcool.com to anyone looking for high quality cooling gear. Hope this helps.

i think it might be ur psu. 250watt is too little for an 1.3ghz tbird. I know u need ATLEAST 300watt for an tbird 750 so im pretty sure its ur psu

I have seen this proble a lot and what I think causes it is that the cpu is getting just enough power when running on it's own, but when you enter a 3d game and the graphics card starts drawing more current the cpu is not quite getting enough and crashes, upping the voltage to the cpu by 0.05 or 0.1v usually solves this problem

I was only having problems in Tribes2 and realised that it was caused by IRQ sharing. My sb live was hogging up IRQs like it does on all KT133 boards. Once I disabled SB16 emulation, the IRQs were shared properly and I havn't seen a crash since.

Check Sandra and see what it says about your IRQ sharing.
