Hi Andre, I just found this forum and your extremely informative posts. Thank you for sharing your expertise! I am currently running a new desktop with AMD 4100 quad core processor, 3.6GHz overclocked to 4ghz with 32gb of high speed ram and a 1tb seagate hard drive running at 7200rpm. I am using Windows 7 professional. It's a clean install and when I first booted it up it booted in just over 43 seconds. This has now gone up to around 125-150 seconds according to the Event Viewer. This is really insane considering how much power my system has and how few apps are installed. I was wondering if you could help find out what is going on and how I can get it back down again? I have applied all the patches you recommend, gone through the superfetch training and cleaned up my startup apps using msconfig and defragged but it has only really cut off about 15 seconds from the boot sequence. I have created a boot trace which I have uploaded here: https://skydrive.live.com/redir?resid=36C44C03C4D93E47!2799&authkey=!AO4jKn0ovzxMNC0 And here is what happened before the optimisation: https://skydrive.live.com/redir?resid=36C44C03C4D93E47!2803&authkey=!APxdvN9DixgsFkU and after: https://skydrive.live.com/redir?resid=36C44C03C4D93E47!2804&authkey=!AEltdbnbzRMDMZg Any advice you can give would be much appreciated as I cannot fathom why my computer boots so slow given how much power it has.
