Windows 7 ulti - 64 bit - 7601, SP1, Programs Not respoding

Hello as my title says after installing sp1 my system or let's say "task manger" not responding.

When this occurs i can do alt tab and the system response is fine.

i didnt had this problems at all at the beggining and my machine is pretty fine and new to have that kind of problem.

Also i update my bios to see if anything change nothing my memory is good..

but i dont know what else i have been searching about 1 month and i found 1 hotfix that microsoft release after sp1

Computer randomly stops responding because of a deadlock situation in Windows Server 2008 R2 or in Windows 7

Button nothing change.

Also i did unistall my firefox cause i thought this was the problem for 1 day it was good after again the problems start i am start thinking that the adobe flash player is the problem..

Any ideas thoughts thank you..!

Thank you for the quick response,

I will try and reply here, and for the record i remember that when i was trying to install the sp1 i had some problems maybe some files missing.

We will see.



*update*

i downloaded and install it.

i saw a different when i did the restart more faster than the previous time and i dont see a lot not responding but still testing :)

Have you recently changed/installed any hardware?
If so, make sure that all of your RAM sticks, power and data cables are properly seated in their sockets.


Remember to turn off the power first (at the wall socket also)!
Make sure that you touch the metal PC case to dissipate static, BEFORE touching your RAM.



Maybe you could run "Task Manager" (split screen) and a program that has the problems (e.g. Firefox?).
Have "Task Manager" set to the "Processes" tab and check to see if any processes are suddenly using up all of your CPU.

It depends on the process.
If you notice something like that happening, you could report it here and someone might be able to suggest a remedy.
Also you could do an Internet search about the process in question and see if there have been any reported problems with it.

It might even be a malware/virus process, disguised as a legitimate one.
