I've got a system that is often (but not quite always) very, very slow. Slow to load programs, slow to switch tasks, slow to register clicks and keyboard input. It seems to come down to HDD performance absolutely tanking.
If I run a benchmark while the system is 'fine' then hdd performance is normal. If I run it when the system is slow, everything else is normal, but hdd read/writes are maybe 10% of normal speed.
Is there an easy way to tell if this is a disk problem or a SATA controller / motherboard issue?
Notes if needed:
It's a quad-core with lots of RAM, and (when it is slow) always shows plenty of free cpu and memory.
I've (repeatedly) used adaware, spybot and malwarebytes scans and can find nothing.
