I am looking at a laptop for a friend, originally I was told that after an upgrade of norton antivirus it started to freeze a few minutes after startup.
I got hold of it and noticed it was freezing whilst booting also. I finally got it started and after a few freezes I got uninstalled in safemode but after a while it was still happening so I booted into the recovery screen and reset back to the factory image.
Again it started to freeze and it took me about 7 freezes before I manage to initially get it booted into windows. I have ran the hard drive diagnostic in the bios, it passes the quick test and then gets to 80% of the comprehensive test, hangs for a bit and then turns itself off.
It gets really hot around where the power adapter plugs into so I'm not sure if it might be overheating
