The newest G15 is now three years old - - whether you purchased it used or as very old stock, contact your seller if it is not performing correctly. None of the G series will be under Dell warranty any longer.
Step 2 look at the manuals page for your model on the dell website, specifically if it has a CMOS coin cell battery that may need changing, and / or to clear the CMOS and start afresh, taking pictures of the BIOS screens to reset/compare settings after a reset/refresh.
Then ask again if you need more help, supplying details about the system.
You could try a Linux and see if it is more stable as a LIVE (not installed) version for a test to compare against whatever MS OS you have.
But either way more details and a more open mindset.
