And if yes, is it possible that those performance > issues come with no notification in the windows log journal ? A few months ago I was (apparently) having random total freezes on my computer. Considering that it was when it got hotter and that I had a fanless graphics card, I replaced it with a fan based graphics card. There were no traces in the windows event log While it helped a bit, the issue came back but this time I noticed that it actually happened when accessing a particular file on one of the harddrives inside the computer. And yet, no traces in windows event log. However, using tools to read the SMART values for this harddrive, I noticed that it had been eating up spare sectors for quite a while. I replaced the drive, and haven't had any issue since then, when I was having an issue at least once a day before doing so.
So to answer, yes, it is definitely possible that the hardware is crashing and windows does not notice it.
