Freezing/Crashing

I have a Samsung Chronos Series 7 running Windows 7 and as of a day ago i have been experiencing extreme stability issues, freezing programs and general unresponsiveness. Whenever I boot up my computer and log in, within 5 minutes the system freezes, with the only way of shutting it off being to hold down the power and force reboot. Each time windows boots up, within a few minutes of logging on the system freezes again.

After repeating this a few times it eventually would boot up, but freeze between the windows screen and the log in screen. The mouse was functional and could be moved around the screen but it was frozen at a black screen. To fix this I ran a system restore through the BIOS. This corrected that problem but I am still left with the problem of my system freezing every time it boots up.

I have run my anti-virus (Kaspersky) and malwarebyes, neither have found any sort of malware.
