Report "Have a AN7 I system I am upgrading to Win 7 and upgrading the RAM. I pulled a stick of RAM out and replaced put the same stick back in. Afterwards, when I try to reboot I get 04 when power is applied, 83 when attempting to boot, 98, then 99 and it shuts down. I tried clearing the CMOS to no avail. Any ideas would be greatly appreciated"
