AMD/NVIDIA CONFLICT?

I havent ever heard of a "Jet" motherboard company, nor can I find it. I recommend that you flash the motherboards BIOS again.
Also, if you can find an updated driver for the motherboards chipset it might help. (it's a longshot)

Tell me how it goes

before you start flashing the bios, think that the problem is most likely the card driver, or its configuration program, as you say that it has happened on a board with same card, but different configuration.

Get into msconfig, selective startup, and startup options tab, and uncheck any references to your video card

( these would be on the fly resolution changers that load up in the system tray ).

also look in autoexec.bat and config.sys to see if any dos drivers are loading for thevideo card. ( happens sometimes, if the install program senses you have some dos mode games )

Before you reboot, set the screen resolution to what you want it as.

See if the problem doesn't clear up. Had a very similar,nasty experience with acreative
graphics blaster exxtreme.

Then, in the meantime, look on the manufacturers website for updated drivers. Usually the ones that ship with the card are way out of date.

One last thing to check, but very unlikely, is to disable any accessability functions which might have gotten turned on. My son thought it would be fun to hotkey my spacebar to the Zoom mode....

The key here is that it works correctly most of the time, but there is only a problem 1 out of 6 boots (or about that). It's a power problem. Do you have the system on a power strip that you turn off? If so, take the computer AND the monitor off the strip -- they need a small amount of power, so that they can save their settings (and or) power up in time to communcate with each other.

If this isn't the case (no power strip), This is the more likely culprit: The problem lies with the powersupply residing in your computer. Swap it out for a bigger/better one. You don't mention what else you have in the case (Drives, or other power grabbers), but most of the time that I've seen problems like yours was the result of a "cheap" power supply -- AMD now has reccomendations on their website about power supplies!

This should help!

it is an NVIDIA card, go to their web-site and get the TNT PRO2 driver and try it. I had a similar problem and the driver solved it.

Like caller #1, I have never heard of a company called "Jet" that makes motherboards. Since I know nothing of this motherboard, I'll leave troubleshooting it to you. However, I use an AMD K6-2@500 on an Epox motherboard (model EP-MVP3-G5) with a Hercules GeForce GTS. When I first built the system, I hadproblems like yours. However, that turned out to be poor driver implementation. I downloaded the current Detonator drivers from nVidia's web site and havent had the problem since. I would recommend that you try installing good drivers (never heard of Sparkle either), before you start messing with the BIOS.

Since I am unsure as to what you mean by "latest drivers" I am going to make the assumption you mean latest official drivers from nVidias'web site. That being the case I would suggest that you go to www.reactorcritical.com they maintain a library ofall the beta releases that are not kept at nVidias site. I had to go through 6 or 7 beta drivers before I found one that would work error free with my Win2k on a KT7 Raid with 900 TBird and a TNT2 M64. None of the official releases would run 3DMark without hanging up.

Thanks to all who tried to help , but this time no-one got it, the answer was an update of the ALI CHIPSET AGP MINIPORT DRIVERS ON THE MOTHERBOARD.
