mno tak toto iste robi aj mne... mam GF4 MX 4000 (takze len sunku oproti Tvojej), ale popis zavady je rovnaky... vid. :
http://4um.ocguru.cz/viewtopic.php?t=82824

a to soms tou kartou nic nerobil.... ani netaktil, ani NIIIC... Myslel som si,ze sa prehrieva, ale ani pridanie 2 chladicov do case (jeden z nich fuka priamo na pasiv karty) nepomohlo...

Skus mi sem napisat, ake mas v tom kompe ostatne komponenty mozno ze nam z toho volaco vyjde....
ja tam mam :
grafika : ASUS V9400-X (GF4 MX 4000)
mboard : ASUS A7V600-X (Via KT600)
Ram : 256 DDR400 Mercury V-Data
procak : Sempron 2200+
Case : bezny s nejakym 300W zdrojom zevraj LC B300

procak je chladeny kvalitnym chladicom s medennym jadrom aj case je dobre vetrana, takze v teplote problem nebude...

na chvilu sa mi to podarilo rozbehat a to tak, ze som do kompu strcil grafiku MSI GF5200FX (ked som este nevedel presne, kde je chyba)... bez preinstalovania ovladacov ju system rozpoznal ako 5200FX a bezal bez chyby... Tak som ju vytiahol a zase dal naspet tu GF4000... zase ju bez nutnosti instalacie ovladacov rozpoznal system spravne a chodila az do chvile, nez som na kompik priinstaloval tlaciaren... potom sa to zase posralo... a kedze uz som nemal ty 5200FX (bola len pozicana) uz som to nerozchodil.... a tosom skusal toho dost (ved pozri moj thread)... Az na volaco pridete, napiste..... inaq pisal som aj na SUPPORT do ASUSu a tu je odpoved :

Dear Friend :
Thank you for contacting ASUS Customer Service.
My name is Lucifer and I would be assisting you today.

My friend , according to the status you described ,please follow the steps below to have a try :
1. Please check whether the CPU is overheated, because the CPU is almost fully loading during you run 3D games.
2. Please check whether the VGA chip is overheated. The defective fan on the card may cause the VGA chip overheated so that the system will be unstable.
3. If you are overclocking your CPU, VGA card, memory or others, please restore the default setting.
4. Always, we recommend you updating the VGA driver to the latest version for better compatibility.
5. You also can disable "FAST Write" in Bios setup to have a try.
6. If this problem doesn’t occur before, and only occurs after you have installed a lot of software in the system, this may be the software conflict. Please remove some software to have a try. But we recommend you reinstalling the OS for best solution after you backup your datum.
If these cannot help you , would you please use this card in another system to have a try and see whether the card is broken. If the phenomenon reoccurs , you can use the ASUS RMA service.
If you need ASUS RMA service ,please kindly contact with your local reseller where you bought the product for RMA service request. If they cannot help you solve this problem , the local reseller will send them to us through distributor for RMA. We will solve your problem as soon as possible.

Sorry for any of your inconvenience.
If having any problems, please don't hesitate to let me know. Let's discuss this issue together.
Thank you for using ASUS products and enjoying ASUS services!
