Thanks in advance for the BSOD help. I am at my wit’s end on this computer (eMachines T5226). We have been having BSOD problems for months. I ran memory tests for days with no luck. I ran disk checks. Finally, we thought it was Norton 360. I removed it and the problem went away for a while. Then it came back. I increased the memory from 1G to 2G and the performance seemed better, but I still get the BSOD (almost always the same error) I tried removing other software with no luck. I finally did a complete Vista reinstall from the eMachines recovery disk. It seemed better for a while, but after all the Vista updates were installed, it started getting BSOD again and now they seem to be coming more frequently. From what I could tell, it seemed the defrag utility was causing it to die. On one day, I got 11 crashes. I turned off the scheduled defrag and the frequency of crashes got better. I ran the defrag manually with no problems. I attached several minidumps in the hopes that someone can give me a clue.
