I hand windows 7 64 bit, i have the AMD FX 6300 six core processor each core overclocked to 4.4ghz each, and a 2gb AMD XFX R7870 core editon GPU. So alot of my parts are up to date and so are all of the drivers. But my hard drives is about 3 years old. Could the hard drive affect the speed of my pc, i mean it has been crashing alot and sometimes even struggles to load up google chrome. Although after my computer has already been on for about 3 hours my system starts working faster?
