I had an i5 650 on this desktop, then I decided to upgrade it to an i7 870, but for some reason it's taking about 5 minutes to boot from hdd (it'd take about a minute before), and the computer got slower as well.
I tried reinstalling the chipset drivers but nothing changed.
From what I tested, the CPU is about 60°C idle, could it be because of this?
Does anyone know what the cause might be?
