Put together my own computer and I don't know how to system restore it

Hi. As you can guess, my computer doesn't have 'factory settings'.

I'm not all that versed in computers and this is the first one I've build on my own, however, it's beginning to run very slowly and I would like to completely restore it back to it's original form, from when I first built it.

I have my windows discs (but i don't have the drivers for my hardware, which I'm assuming I can find online).

Is there a way to restore a home build computer? Everything I've read talks about 'factory settings'.

Thanks!

Yes but you would have to lose all you data. You would have to back it up. All you have to to is reinstall Windows. But make sure you have your Network driver first. All the other drivers can wait until you install Window. I would also recommend is after you install Windows and get all the software you use on it. Is get a external hard drive and make a image using windows backup and back you pc up every month.

Depending on what is causing it to run slow, you may not need to reinstall Windows.

Have you tried "System Restore", a function built into Windows that has nothing to do with a reinstallation of Windows? It simply restores your registry to a previous time when Windows was NOT running slow.

Once you have a stable system I recommend you make regular IMAGES to an external HDD then you will rarely need to reinstall when things go bad. Images are a snapshot of your HDD and will return everything including OS to the state it was in when the image was made. You can reimage to a new HDD if your old one fails.
I use Windows inbuilt imaging (see the tutorial section for making & restoring)
and
free Macrium Reflect. This is highly regarded by Forum members.
