Having problems with your Dell Dimension 8400 PC Desktop ?

Will Dell optiplex P4 1.8Ghz CPU work on Dell dim8400 LGA 775 MB?

\015 Normal\015\012 0\015\012 \015\012 \015\012\015\012\015\012\015\012I have non-working Dell Dimension 8400. I am\015\012trying to figure which component/s have gone bad. I dismantle all the\015\012components, removed cpu, heat sink, cleaned applied thermal paste, got 500W new\015\012PSU. I first tried powering up just the MB no beeps, I placed CPU on MB and\015\012powered up I get beeps. 6 Long beeps G,Y,Y,Y. I tested again with 1GB stick on\015\012DIMM1. I get 2 long, 2 short, 2 long beeps back panel shows G,Y,G,Y. I took off\015\012the CPU power connector, switched on the power I get no beeps. I don't get any beeps\015\012when I take off 4-pin CPU power connector. I am wondering if its the bad CPU? I\015\012went through each capacitor to see if any bulged or leaked ones, I found none.\015\012Why would I get G,Y,G,Y which is memory error beeps if its a bad CPU? I have\015\012another Dell optiplex P4 1.8 Ghz. Just to test, I was wondering if I can try placing optiplex CPU\015\012on Dell 8400? Will P4 1.8Ghz CPU work on dell dimension 8400 LGA 775 MB? This will help me eliminate the problem. Any\015\012inputs would be a great help. I was think of getting a new board, now I am not\015\012sure if it\342\200\231s a bad CPU or bad MB? What a pain.\015

How do i change the memory bus speed on my dell optiplex 170l? The CPU is an Intel Celeron 2.4GHz. The mother board processor speed is 400MHz and the Bios indicates a memory bus speed of 266MHz and does not seem to have an adjustable option. If the CPU can run at 400MHz then why can't I get the memory bus to run at 400MHz? Origanuly this system was shipped with 2 X 128MB 333MHz DDR CL2.5 Non-ECC DIMM modules and yet the bios indicates memory speed at 266MHz.
