I was referred by a friend to this site cuz I was having a problem with my Computer and ask for his help. I have a P4M890T-M MoBo with Celeron D on it and 1.5(one 1Gig and one 512) Kingston DDR2 533 Memory. Then I just recently bought an Intel Dual Core E5200 Processor. I installed it properly but when i boot it a Message "A 200mhz system bus processor is installed. The processor is not supported on this system board and will run at reduced clock speed." appeared. I do not know what to do with this. Can somebody help me? All suggestions are very welcome. Thanks in advance!
