You could have a bad mobo. Why don't you clear CMOS, by first turning off the power, and then removing the battery for about a minute. Now, reinstall battery and RAM. Power it up. Any changes? If yes, get into BIOS and manually set your DRAM options to the specified values on the RAM label or packaging.
If not, try the other set of RAM. If still no display and still getting the memory error beeps, RMA the mobo.
Thanks, even though that didnt work, my new gigabyte motherboard is on the way. Appreciate the reply. I guess 140$ to fix my computer isnt to bad considering how much it cost!
