Abit KT7 BIOS checksum and lockup probs

I have just got a new Athlon 900 and Abit KT7 board. I hooked everything up fine and powered it on. I immediately got a CPU is unworkable or CPU settings have changed error. I tried resetting the CMOS through the onboard jumper and then it gave me the Checksum error - defaults loaded error. I took out all of the peripherals except for the video card and fddrive. It boots up sometimes now with the checksum error or it just locks up totally after it counts the RAM or it counts the RAM and then it lets me go into the BIOS and look in there a little bit and then it locks up on me and then it loses video display or it boots up with no display at all. It also goes through the post fine with one beep and then does not even try to access the floppy. I read the other post on this and I have some of the stuff I have already tried or some that I can't even do.

If anyone could help me on this, I would GREATLY appreciate it because this thing is driving me nuts!!

Thanks
 
I am sure you have done this but go back through and check all of your connections
to make sure that everything is hooked up properly. Also, is there such a thing as
a bad cable? You might try to hook a new cable up to your hard drive. I would be
interested in hearing what some of the other members have to say about this one.
 
My first thought would be to flash the bios but with that unstable of a system I don't think that would be a good idea. So sorry I can't help directly but this link might be of help. The one idea I did have was to reseat the CPU and make sure there is enough thermal grease or thick enough thermal pad between the CPU and heatsink to insure the the CPU is not getting too hot.

Good luck

OK, what you needed to do with the first error is disable the "speed error hold" option in the softmenu setup. It defaults to enabled and will stop the boot process with anything but default processors running at default clock speeds. If you can get into the BIOS settings, be sure to disable any BIOS ROM caching or shadowing. Do the same for the Video BIOS. Make sure the processor is getting the voltage it needs, set it up a notch or two from the default to make sure. Check that the memory timings are set to the most relaxed values. If you can't access the BIOS long enough to accomplish the above, try using the "load setup defaults" option at first access then you will need to repeat the above.
Remove or try another DIMM, you could have a bad memory module.
CPU could be bad
Mother board could be bad.
Good luck!
 
I have tried the things that you guys suggested and some other things but to no avail. I am sending it back and getting another and hopefully it does not do the same thing again.

Ace out....
