OK , I have an ASUS CUSL2-C mobo , 256 MB stick Infineon , Retail Radeon 64MB VIVO . I just put the system together . I loaded W2K with no problems . I did this on a test bench I have set up . Satisfied it was ok , I moved the system to my desk and hooked it up . Now it's making the long , single beeps indicating a problem with the ram . I have tried re-seating the ram several times , tried several different sticks , with the same results . I'm not real sure what to try next . Any help would be greatly appreciated .
