Computer slowed down drastically

[angrywasp]

I have a Dell Inspiron 1720 with Vista SP1. I got a virus about 2 weeks ago and re installed Vista. Everything worked fine for a week, then the computer became slow at some point. I use the computer for music production so I noticed everything slowed down because my projects were suddenly overloading the system.

Anyway, I have tried to work what is wrong. I have scanned with Kaperksy, Ad Aware, Spybot and not found anything. I have checked device manager and everything is working fine. There is plenty of space on the hard disk. I have checked programs running at startup and disabled any unnecessary. I have checked disks for errors.

So what else could it be? And everything worked fine for a week after re installing the operating system, then everything seemed to suddenly slow down. I had been installing a lot of software, but only programs I had on before I re installed the operating system.

Any help appreciated

Did you re-install your MBoard device drivers ? ?

There is a feature where you can restore the OS back to what is was like when the computer was new, so I just used that. It worked for about a week then everything slowed down.

Do you think I should re install the Mboard device drivers then?

It won't hurt anything...
Depending on how the restore CD/partition was created they may have forgotten a few important details.
