The single click sound indicates that the CPU card was not fully seated. Now that it is, the crashing glass sound is made when the RAM check fails. When you swapped out parts, you did press the CUDA button each time. The next test would be to put in only your two old 32MB DIMMs and see if you can boot. If that works, add one 128 MB DIMM at a time. If the 32's don't work, try pulling them out and adding 1 128 MB DIMM. Each time you swap RAM, you are using good static protection and making sure the RAM is stored in a static bag when not in the machine. -- -- Mr. PopMan - [EMAIL PROTECTED] - "Does anybody want to play a game of pinball?"
