Sounds like it is overheating. Can you open hwmonitor to watch temps until it shuts down?

Run chkdsk /r on your hard drive by going into My Computer > Right-click on C: drive > Under Tools Tab > Error Checking > Select both check boxes and click Accept. Restart your computer and let it run. Be sure your AC adapter is plugged into the laptop.

The next step is to review the Windows Event Logs during the time of the shutdown. Most the time there is an event that will give you some insight into the restart.

How are you touching the cpu? You mean you are removing the heatsink and touching the cpu every time it shuts down? It would be cool by then...

The heatsink? If the heatsink isn't getting hot then there isn't good contact with the cpu, hence the cpu overheating. Did you clean off the old thermal paste and reapply when you took off the heatsink before? Use hwmonitor for temps, your finger is not very good thermocouple.

The CPU temperature too hot can cause this, just turn off the option: AUTO shut when CPU temperature over 80 degree. But this can burn your CPU sometimes, you need to clean your laptop inside CPU and fan,
