Windows 7 desktop computer extremely slow

I have a problem with my Gateway DX4831-01e desktop computer (1 1/2 years old) which is running Windows 7. 

Last week, something happened (I don't know if it was an upgrade or a virus) but Windows 7 (64) started running extremely sluggish.  I restarted and it was extremely slow on start up.  I can get into Safe mode but it takes a couple of hours to load all.  I can still access my hard drive and files there and I can plug devices into my USB ports (to allow backups and to load files for running)

On start up it goes from the Gateway screen to the Bios screen and then starts acting slow.  Pressing F8 over and over gets me into Safe mode but it is very slow and during driver loading, it seems to hang up on the ClassPNP.sys file, but it eventually loads all(after an hour or so). 

 I have tried many things including running System restore and repair and running sfc /scannow (took overnight), removing AVG 2011 free (my virus scanner) and all of the folders that the AVG removal tool didn't remove, and deleting Temp files. 

One other strange thing I noticed is that in my Start up programs (I use selective start up) there were three checkboxes for starting up a Java update, and Adobe reader and Adobe acrobat.)  I removed all checkboxes but the system gets slow before I even get to the start up files, but it was strange and might point to the cause of the big problem.

 My questions are, what is happening between the Bios screen and the driver loading screen that would slow it down?  Could it be prefetch or start up file loading?  I don't think so because I haven't even gotten to the Safe mode choice screen before the slow down happens.   

Should I erase Prefetch or remove and reinstall the button cell battery to reset Bios?  Will it ask me for a password on restart that I know I don't have? 

Thanks in advance!

HI,

Gateway should have documentation on installing Windows on a new drive. And

they will sell the installation media cheap, if you need it, since you already own

Windows. Once you have the correct disk the installation is very straight forward.

The Repair Disk you made is not an installation disk.

Hope this helps.

    What happens if you uninstall the ghost devices? Do they return after a reboot?

    Make sure all other security software has been disabled and cleanup first as suggested in my earlier post.

    I could run Ccleaner and then reboot to Safe mode and then run the TDSSKiller from Safe mode.  What about those ghost devices?

    Do I have to reboot, or can I just run TDSSKiller right away from this Safe mode session?
