I have got below laptop configuration:
DELL Insiprion Windows 7 Home premium Ram 4 GB Hard Disk 500 GB Processor Intel core i3
My Laptop was working fine till this problem occurs, suddenly from last two days, whenever I start my laptop it starts perfectly and after working of 30 minutes or 1 hours it gets hanged and then there is no way to do proper shutdown.
Finally, I have to do Hard Shutdown by pressing the power buttom. I have tried a to restart the laptop and problem is same after using 30 min to 1 hour it get hanged.
I have run CHKDSK but no luck, I though there may be heating issue to I bought cooling pad.
Please suggest how to fix this issue, do I need to reinstall windows 7 or my hard drive/RAM is having problem.
