Hi S-shrestha,
Thank you for visiting the HP Support Forums and Welcome. I have read your thread on your issue with theHP G71-340US Notebook not starting correctly. You could follow this link on performing a hard reset.
Please note disconnect all external connected peripheral devices such as USB storage devices, external displays, and printers. You could try a system restore. When you use System Restore to restore your computer to a point in time before an issue began. Choose the steps to restore your computer when Windows does not open normally.
Hope this helps.
Thanks.
