You can also find the files we need to see in a folder marked minidump. This is found in the main Windows foler.

Simply zip up the contents and post them for us to take a look.

I didn't got a chance to run those but got same error multiple time as I had to format the laptop and I updated the driver and things were going good as when I took the help of a mini tool partition maker to get the exact size of 160 gb and the rest for d drive it got created but the laptop got extremely slow and had the remove that partition and tried to re partition it gave error of preforming chkdsk I did that also and then I recreated the partition as now the laptop is till slow but running ok I am doubting the HDD but the test of laptop diagnose is pass .

What about recovery partition:
How do I access Lenovo recovery?
Reboot your PC. When Lenovo Logo appears on screen, press F11 to enter the hidden restore partition. At the Choose a recovery tool screen, click on LenovoProduct Recovery.

Sorry for late reply but the issue solved I ran in recovery and did a reset and it boot and ran properly as I then didn't wasted any time in updating drivers and os I just configured and gave it to the user.

Thanks
