random reboots due to bad hardware?

[JayUK20]

It started two days ago when my laptop was idle and suddenly rebooted and kept rebooting.

What would happen was on the windows 7 loading screen it would just turn off and sometimes it could boot me to the desktop then a few seconds or minutes later it would reboot.

I booted to safe mode and everything worked perfectly so I thought it was a software issue ax I had run diags on ram, hdd, USB ports, processor and gpu etc with PC check and it came back pass on all hardware related tests. I ended up wiping the disk and trying Linux and sure thing, as soon as Linux mint starts to load the system reboots. Again sometimes I can actually use the laptop for several hours before a reboot.

When windows 7 was installed and the reboots happened I had no bsod errors or anything, event viewer told me there was a kernel power issue, Id 41.

I'm currently trying memtest to double check ram but I am now totally out of ideas.

I'm not sure if there are any other tests I can run? I even added fresh thermal compound to the processor and gpu.

My laptop is an Acer 4060

go over to cpuid.com and pickup HWMonitor. Check your temps and report back. Did you run an off-line RAM diagnostic like memtest86, and for how long?
