Hi,i need help for one thing.Whenever i boot my pc it says this before loading windows:

Alert ! Memory failure detected in DIMM3.The amount of system memory has changed.

Strike the F1 key to continue , F2 to run setup utility

Press F5 to run onboard diagnostics.

This error started 2 weeks ago , and i have no idea what to do;.Please help me
 


I switched ram from DIMM3 to DIMM5.Now its giving me this text:

The amount of system memory has changed.Alert ! Non optimal memory population detected.To maximize performance populate DIMMs as specified in the service manual.Strike the F1 key to contiune , F2 to run setup utility , F5 to run onboard diagnostics.

I don't have any service manual.
 
First pull the second CPU riser out and back, at least twice (while air cleaning the pins and fans). then,
if it does not work, switch between the memory sticks. If it dos not help, head straight to the CPU socket or sockets, if you have dual.
With an LED flash light and magnifying glass look for bent pins. Mine had three on the board socket under the arrow of the CPU. Straighten them up, place back the CPU and have a great day.
Beware that this was my solution, yours maybe different.
