HP G61, Win7 Home Premium, Rollback RX disk management
For one thing, there's the occasional disk thrashing which makes everything else go mega slowly. Maybe, just maybe, that's something to do with Rollback, since I can't see what's doing it in Windows Resource Monitor.
What I am more worried about is the fan. I have previously had a go at dismantling and cleaning, but I couldn't get past a particular screw. Being a notebook, the fan assembly is custom. A few months ago everything was dandy. The PC started up practically silent, and then after a while the fan started gently, and if I was doing something demanding the fan throttled up.
A few weeks ago, the fan started coming on full blast from the start. I was worried what caused it, but didn't consider it critical because obviously the cooling was running.
Now it has gone to the opposite. No fan at start up until quite late on, when there starts to be a warm smell and the case feels hot, then the fan does start but is quite feeble. This is alarming. I have installed a CPU load and temp monitor, and things seem to tick over at 53°C once the fan is running and at light load; a max of 63°C has been recorded, but the monitor has not been running during an extreme yet.
