Symptoms:
After shutdown you turn on the power, but the system displays a blank screen, lights and fans are on, but the system fails to POST (Power-On Self Test).
Usually you can't power back on for at least 5-10 mins, sometimes up to an hour and in some rare cases even after a day. And even during those attempts you may need to press the reset button in order to get it to POST.
Swapping out to a PCI card or a different AGP card (not GeForce) usually gets rid of the problem.
Cause:
This discusses the GeForce2 incompatibilty issue. It stems from a PWM (Pulse Width Modulation) circuit on the motherboard being incompatible with the GeForce's power unit. The incompatibility applies to GF3s as well.
I've seen some posts that say ABIT aknowledges the issue. (eg. http://www.btinternet.com/~p3v4x/texts.htm) You can RMA your board and they will replace some capacitors to fix the incompatibility. Doesn't help me tho, since I have an IWILL KK266-R. No response from tech support, yet. Will any other manufacturer step up to the plate? Anyone approaching tech support should go in armed with the aforementioned article.
Solution:
A) RMA as above, but if the manufacturer just swaps mobos, you have the luck of the draw whether or not the new mobo will exhibit the problem.
B) http://www.chewan.freeserve.co.uk/
For the adventurous... Here's a KT7 mod that by-passes the PWM circuit (and thereby by-passing the problem) by connecting the PSU's +3.3V line directly to the I/O power line on the mobo.
This mod would need to be modified for all the other mobos. I don't think I have the guts to try this out, tho. Anyone else do this yet?

I just confirmed that the KT7 mod works on the KK266/KK266-R.
