I have a CyberMax pc with the Micro-Star MS-6167 motherboard and an Athlon 650. I have 256mb, and am running Windows ME, and have the latest Award BIOS (tried both 1.5 & 1.6). Everything was working fine.

I decided to upgrade to an Athlon 850 from Motherboard Express. After
installing the new CPU/fan the system will not boot at all; no beeps but it sounds like it is accessing the hard drive for only a couple of seconds. Also the system is powered on by simply plugging it in. The primary on/off and reset switches on the front of the PC can't turn off or reset.

Motherboard Express sent me a replacement 850, but it has the identical problem.

I have reinstalled all of my memory and cards in case something got loose
during install but that didn't help. I went back to the original Athlon 650 and everything works fine.

I feel like I am missing something minor, but I have searched all related web sites to and have found no hints.

Is there something you can suggest that could get me up and running with the Athlon 850? Thanks ahead of time for your assistance.

Make sure the CPU is properly installed, oriented correctly, and well seated in the socket/slot...whichever...

Motherboad manual can be found at MSI Tech support (http://www.msi.com.tw/support/index.htm)

The CPU voltage and clock frequency must be set in BIOS, check the manual for details.

If you had everything...Where would you put it?

I've tried re-installing several times, making sure no other memory simms or the video card has not come loose.

I gone over the bios manual and there is nothing to change; the bios is supposed to auto-detect any CPU changes.

This has happened to 2 AMD Athlon 850s. The original and the one Motherboard Express sent me in replacement.

I think that the MS-6167 just can't handle the 850, even though I've read that it can.

I think the power supply might be a possible suspect. You may need to consider getting a 300W unit to keep up with the higher current demand. Do you have a meter to check the 5 and 12 volts? An easy place to check is on one of the drive power connectors. Maybe someone else will have an idea before you spend the money on a new one.
