I have a HP Touchsmart 600-1155 All-In-One computer and recently has started to power off by himself (like long pressing on power button) every 2 hours 1 minute and few seconds (on the clock). I have never overclocked it and no drivers or devices was installed recently (os it`s out of scheme because it happens in bios too).
What i have tried so far:
- Checked temperatures (all ok)
- Checked voltages (all ok)
- Ran hp diagnostics (a tool that can be started at boot)
- Reset cmos
- Checked windows logs (nothing relevant. also OS is not relevant because it happens even in bios).
- Replace thermal paste on CPU and Video
- Checked all fans/coolers
- Reseat various components like hdd, dvd, minicards etc. (read somewhere that this action can do magic sometimes :) )
Also i cannot run memtest properly because the 2 hours timeframe but the hp tool says there is no problem.
I am aware that can be the PSU and i cannot replace it right now but i cannot explain why 2h 1 minute every time... even if i power it on immediately and do a stress test on him.
If you have an idea i am open to test it :)
Thanks,
