Ive been having a problem recently with my self-build computer. At first I suspected maybe a defect hard drive but when I play games it never freezes. And both google chrome and mozilla firefox is freezing VERY often. I tried disable shockwave flash but the browser itself fucks up. Sometimes spotify fucks up, no browsers want to open and it takes 2 minutes for them to actually open completely. I tried a disk check for errors but it didnt find anything. What can be wrong?

(PS: Also tried to replug cables for mobo etc)

Specs:

Sabertooth p67 mobo
Nvidia GTX 650ti boost 2b ddr5
OCZ Vertex 3 128 gb SSD
Seagate barracuda 1 terabyte
Corsair HX 750W PSU

Coolermaster HaF 932 rig
Standard DVD/CD reader/writer
