It is hard to tell. You need at least an oscilloscope, and understanding of digital electronics. When chips go bad they usually quit oscillating. An easy way to find out it is oscillating is by using a multimeter, and checking the frequency of the output, and the input pins. This test will not tell other problem with the chip tho. It will only tell if the chip is completely bad.

If the RAM had got kaput then there would be continuous beeps coming from the MB speaker. Press all power plugs firmly, clean the RAM contact points with a pc of normal white paper, look inside the CPU. There should be a greenish LED lighted as long as the mains are connected & if its not, straight away change the SMPS(power supply inside the CPU), otherwise see that the power switch is connected. Also check the snugness of all cables including RAM slots. If the processor fan starts, but no display then check for any bent pins in the mouse & keyboard PS2 jacks(see to it that no key in the keboard is constanlty pressed/depressed). If still no display then use your older RAM only. If no success then change the SMPS.of the save 400-450 VA(watts).............sodeep
