Windows 7: Computer runs really slow in normal mode, but runs fine in safe mode

I recently re-formatted my Sony VAIO since it was starting to run super slow. Now that I re-installed Windows 7 on it through recovery disks, it worked fined for about a day but then the problem came back. The computer is slow at bootup and runs super slow while freezing so many times. I am running it on safe mode right now and its working fine.

I ran hardware diagnostics and everything is fine (Memory, Hard Disk etc.)

I installed Norton Antivirus and Windows Live Messenger after the re-install.



Please help me.

anyone?

What software did you use to test the hard drive and memory?

Are you willing or unwilling to do a clean install of Windows as opposed to a reinstallation through recovery disks?

How many items do you show checked in the startup tab of msconfig?

How many processes are running as shown in Task Manager?

1. I used VAIO's default hardware diagnostics tools. VAIO Care
2. Sony did not send a installation CD of Windows 7, instead it asked me to create a recovery disk through the computer so there is no option for clean install.

I am not sure how to provide the answer to the last 2 questions. Are you asking about these things while in safe mode or while in normal mode?

This is a really important problem for me. Can anyone else please help me? I really need this computer working again in normal mode and for that to happen, I need your help. Whoever sees this thread, please help me. Please.

The following processes are running in task manager in safe mode:

I think the 11 Chrome processes are just for the different tabs.

If you need anything else, please ask and I will tell it right away.

I am waiting for your reply.

What do you mean by "show any errors in Device Manager?" Is there a place it would show error? I am able to open device manager perfectly fine. I uninstalled Norton but the problem was still there. I have not tried to uninstall Live Messenger. Will do that now and reply in a minute if it stops the problem.

I tried to uninstall Messenger and it gave me Error: 0x80070641

Hey, I know you are trying to help me but could you please post a little more sooner since I really need this computer working in normal mode. Thanks. I hope you understand.
