Andre I see you are all over the net..
I was going through the trace Windows 7 steps and right in the beginning when you say to change the file name I get this message after entering it into the CMD prompt
xperf: error: boot_base+cswitch+drivers+power_1.etl: The specified path is invalid. <0x800700a1>
When I looked up an 0x800700a1 error I founf the Windows Systirnals page which you were helping there as well.
Basically this all started after I down loaded AVG Antivirus and PC Tune Up. Both worked amazing. PC Tune up sped up my computer sop well it was like it was new again. Then After the first couple of runs I realized how much drag it had on the overall system especially when watching movies. So I uninstalled it. That is where the trouble started. It had its hands so deep in the registry that it screwed my computer when I removed it. All of a sudden my Adobe files wouldn't open. Them my seagate drive and so on and so on. So I had the Geek squad clean it up they found a ton of viruses, Hijacks, and spyware on the computer. They "Fixed it" but it started acing up 3 days later and I had to take it in again. Where they found additional trojans, viruses etc they didn't get before. So now I have it back and it was good for a couple of weeks but it has started to act funny. Sometimes I will have 6 or 7 tabs open and the computer will freeze. If I hit Controll+Alt+Del the screen will go black and then a few seconds later there is a message about some type of warning to save my documents etc. If I just leave it and hit nothing then the screen goes black and it shutdowns and restarts. That is what led me here.
Also occasionally before the computer freezes there is a click click click click like a mini hammer is being used on the inside right of the computer.
I have down loaded and rand the Windows Performance Tool Kit and the DPC analyzer as well.
I am sure this is the wrong place to post this but I had already gone through so many of the steps I didnt know. Whatever help you guys can provide would be awesome.
