I have an M810 mother board and every time I try to run Win98se setup from DOS, it gets to the point of copying needed files to start setup and goes to a blank screen with a blinking cursor in the upper left hand corner of the monitor. I've tried putting windows on the hard drive in another computer and then transferring the hard drive to my computer, I've tried clearing CMOS,I changed monitors, I tried a different windows install disk, I made sure everything was plugged in where and how it is supposed to be and whether I'm trying to boot into windows or windows setup it nearly always gives me that blank screen with the cursor. Although, two out of about twenty times it actually did boot into windows. If you can solve this annoying problem, life would be better. Thanks.

hows the power supply? how big is it?
try a diferant stick or ram.
when it dose boot what temp is it running at?
try a new bootdisk on new floppy d/l one from www.bootdisk.com.
put it in drive and rethan at the a:system c: click enter
after it says system tranferd remove floppy and reboot.

hello that should be a:sys c:

Sounds very much like a weak PSU. Althouth, your board will need to be at least a revision 7.0A to run that morgan duron chip. Check what revision it is, there should be a sticker at the end of the bottom PCI slot.
