I recently purchased a hyperX 120GB SSD, formatted my HDD and installed windows 7 onto the SSD.
Everything boots up as normal (super fast)
did all the tweaks i found on here to enhance the SSD.

After windows installation and update, i had about 80-90GB of free space.

Couple of weeks later, i noticed the SSD has free space of 25GB.

(I use my HDD for applications and downloads) so nothing is installed on the SSD other than windows.

The page file is a hard drive memory cache for when physical available ram gets under 25%.
Its a bone of contention whether you need one with 8gb ram but disabling it completely can cause bsod errors under certain conditions.
If that drive 'd' shown is a decent sized conventional hard drive enable a page file on that instead - the minimum I suggested is fine or if its 1tb or more just enable system managed page file - it will rarely use above 4gb of space anyway.
Hibernation file,page file,windows backup system restore points - they can all eat ssd space.
Disable hibernate in power profile settings,set your page file to 512mb minimum ,1gb maximum if you have at least 8gb ram.
Disable system restore & delete the existing restore points.

I removed AVG and restarted and it seems to have restore the lost space somehow!
Hibernate is disabled and my current Page file is at 0 (http://puu.sh/drD8Z/e50423c41f.png)
what does the page file do?

Thanks for the fast reply.
