I have an Abit kt7a with an athlon 900 that I put together specifically for my visiontek 64mb gts. I have read slot of forums but I still can't solve this problem:

The system will not post. One long beep and two short ones. I have the via 4 in 1 drivers ver...29. I have increased the voltage and pretty much everthing else
that I have read to do. I some one has had this problem and fixed it, please post a message.

Thanks, blf...

It sounds like you can make it to the bios but after that it will not load windows? Is this correct??

If you can make it to the bios try to increase the I/O voltage to 3.6v and change the CPU drive strength to 3. Make sure speed error hold is disabled also.

If you cant get anywhere with it then try turning the power off, remove the mobo battery and clear the cmos with the jumper on the mobo and wait about ten minutes. After ten minutes or so put the battery back, set the cmos jumper back to normal and try to start it back up.

You may have tried some of this, but if not then give it a shot.

I can't even get the monitor to display anything. The motherboard beeps one long time then two short and proceeds to boot with no video. The beeps I have read indicate no video card detected.

Here is something off of Paul's site you might try.

One user found that if he hit the reset button at the moment the motherboard beeped at him (when it failed to find the graphics card), then the machine would then go on to boot fine. This fix was 100% successful.

I just tried that and to no avail. I wish someone would find a fix to this problem. I want my fps back

OK, this might sound obvious, but have you tried the video card in another machine. Even if it was working before, I would check just in case the new board killed it.

Another one would be to try another card on the new board. (you never know...)

Hmm, one long beep and two short beeps. Those beeps are POST error codes, and it is the motherboard trying to tell you something is wrong.
If you go by the IBM POST standard error codes, which most boards go by, one long beep and two short beeps means a faulty display adapter. This could be the card or the slot.
Try the card in another computer, see if it works.
Hope that was of some help.

Get a can of compressed air stuff used on keyboards. spray it in the agp slot and on boad connectors. I found a piece of soft padding from the backside of the motherboard when it was packaged at IWILL.

I had the same proble lately where my monitor would just stay in standby mode. I couldnt even get into bios.

The problem was that the cpu was faulty so I had to change it.
