I have a three+ year old Sony VGN-S260 and one day out of the blue it did not start. Some times it will start just fine, but others it will not. The symptoms are odd because the led lights that display battery, wifi, and hard drive are lighting up as though it is on. Yet, the hard drive is not spinning. I attempted to run hardware tests using a bootable cd, but the cd begins spinning after a little while only to stop again. I thought it might be the ram, but I am having a hard time finding new ram for it because it is micro dimm. Any suggestions?
