Computer goes very slow even after reformatting
I will try to make this story as short as possible, but I am very frustrated on this.
My dad's laptop had gotten a bunch of viruses/rootkits, so I decided to use KillDisk and erase everything with one pass.
Everything gets done and I reinstall Win 7 Home Premium 64bit. Install everything and use the laptop like normal.
For the first five minutes, everything is fine. Loads programs up in a couple of settings.
After the five minutes, it starts getting very slow. The mouse is lagging. Everything takes a couple of minutes to load. The only thing I even did besides have it on was install Windows Update when you first reformat.
After a few more KillDisks and reformatting. the same problem is happening. I know rootkits are harder to kill than most, but can it be possible it is STILL alive?
I also am thinking maybe something inside the laptop is wrong (CPU, HDD.) How would I be able to check this to let you guys know?
I will try the HP Recovery Manager in a while and see if there is any difference.
Please, if anyone could help me and give me at least some ideas to why this is happening.

It's unlikely the virus could survive a simple format or just the Diskpart Clean Command
which wipes the boot sector, although some can get into the BIOS.
First I would concentrate on getting a perfect reinstall: Clean Reinstall - Factory OEM Windows 7 - Windows 7 Forums
Then if necessary compare that with Factory Recover if you made the DIsks or saved the Recovery partition: HP Recover Windows 7 Operating System Using HP Recovery - HP Customer Care (United States - English)
If problems persist test your hardware and work through these other troubleshooting steps
