So after the current tests today and mention of it maybe being a heat related issue i decided to open up my
case and give the inside a good clean, using a can of compressed air ofc.
Bit by bit i removed the various pieces of hardware and cleaned them down, removing all dust from fans etc.
Last to go back into the case where my hdd's, my main being an 80gb (the one with nothing but windows installed)
and the other being the 500gb secondary drive where i keep my WoW installation, photos, other games etc.
It being my most used drive so to speak.
When booting back up the system simply wouldnt boot, and with the case still open i could notice an intermittent 'click'coming from the 500gb hdd.
Ticks every 2 seconds or so.
Knowing that this usually means the drive is, well lets just say 'broken', i removed it from the case, cancelled its startup on boot and the system started up as normal.
My question is could a dodgy Hdd be part of, or the reason for the slowing down fps, especially if the games installation directory was on that drive?
Im guessing theres no way to repair the drive but send it to a specialist, and looking over the net, they all seem to be extremely pricey.
