E Machines W3400 AMD Athalon 64Bit Processor ATI Graphics card. I first troubleshooted the long continuous beeps by taking out everything includinging the cmos battery for it to reset. Which it did just fine. I noticed that the had drive was failing so I ran Hiren's Boot CD to diagnose it. Upon going through this I hard and notice the fan was making noise. It and the heat sink was filthy with tar and dust. The previous owner was a heavy smoker. I removed the fan and tried with compressed air and to brush some off of the heat sink. That didn't work. So I thought to thoroughly clean it was to take it off of the CPU and clean the vanes. On doing so the CPU managed to come with it. I replaced the CPU correctly or so I thought, lining up the arrows and notch in the pins. I replaced the heatsink and fan,WITHOUT pasting it. I got everything squared away and when I turned on the computer it didn't start up. The fans were running full blast without any video, which I had before. To make a long to short, did I just fry the CPU? Or is there something else I've over looked. I didn't have it on more than 20 secs total. 10 seconds at first, then when I tried to make sure the CPU was seated properly. I know this is an old computer but, it has sentimental value to the pesron that gave it to me. I was going to give it back after I had fixed it. (Her father owned and has since passed) Now I believe I've fragged it. What are my options at this point? Salvage parts? Paperweight? Thanks ahead for the help.
