I have a Dell Dimension B110 Desktop computer. I recently tried to upgrade the memory from 256k to 2gigs using 2 1-gig sticks of RAM. After upgrade, the computer would not boot-up and all I got on monitor were fuzzy numbers. I then swapped out the new memory and replaced it with old 256k stick. It still will not boot but I sometimes now get a message stating "previous attempts at booting this system have failed at checkpoint [tmr2]." In addition the diagnostic lights are GYYG which indicates fatal motherboard failure. Does "fatal" = fried in this case or is there something I still can do?
This is not my first time upgrading RAM and I'm sure that the memory sticks are compatible.
I've tried resetting the CMOS by removing the battery for 30 minutes without success.
Anyone have a clue what has happened here? Is my motherboard gone or can it somehow be reset? Can anyone suggest a solution?
Seeing as the message is indicating a problem at one of the timer checkpoints, fatal is probably an accurate description. You are most likely looking at a motherboard replacement scenario. I've seen improperly seated memory modules toast timer circuitry on old boards back in the days when most of the timing circuitry was constructed from discrete components, not entirely IC-based timing solutions, but I have never seen it happen on modern boards.
It is probably that you have a motherboard failure. Are you sure that the memory is 100% compatible?

The 256mb stick that I replaced was 256MB DDR-400MHZ PC3200.
The 2 sticks of of 1GB that I tried to install were 1GB DDR-400MHZ PC3200.
Both the B110 manual and the store where bought identified these as compatible.
