Problem with upgrading processor
Sounds like the processor you're trying to upgrade to isn't the same frequency. The processor, motherboard, and memory have a matched frequency. For example; a motherboard with a frequency of say PC4200 will only accept a processor and memory of a PC4200 frequency. If you try to use PC5300 memory it basically won't do anything, blank screen, or maybe a beep. The same if you tried to use a processor with PC5300 on the PC4200 board. The best way to find the frequency rating is to look on the memory. They class the memory by frequency, but rarely ever list the frequency for the board or processor. Research the new processor to find out the memory class and then see if it matches the memory in your machine. If it doesn't then the processor won't work. If it does, then new processor may not be compatible, and that means more research.
