Hello everyone. I recently bought a 2014 Alienware 18 R1 laptop and I have been having issues with it powering off as soon as I log into the windows desktop.

When I first got it there was a trial copy of windows 10 installed and the first issue it had was it was not detecting the 880m graphic cards. I am a bit fuzzy on this part since I have already spent several hours trying to troubleshoot it, but I believe it started crashing when I tried to install the newest NVidia drivers for the cards. I did some quick searching and found a post saying the cards not detected was typically caused by an outdated bios. I checked and found the installed one was the A10 which was pretty outdated and newest one for it was the A15 bios from 2019 so I installed it and also installed a non trial version of windows 10.  This fixed the issue with the video cards not detected, but soon after the computer starting powering off anywhere between 10 to 15 seconds to a few minutes after I log into windows 10. 

I tried doing some updates in safe mode to see if it was a driver issue, but the nvidia drivers won't install and windows update isn't working there either so I am a bit stuck at the moment. I completed the system diagnostics in the bios setup and everything passed with no issues.  And as far as I can tell, the power off wasn't occurring as long as I was in safe mode.

I tried going through the event logs but there are dozens of errors before each crash so I cant really identify what is exactly causing the computer to power off.  The shutoff is happening so fast I don't have time to really complete any updates or even install the drivers for the video cards. The only lead I have to go on is a crashing issue someone had due to the cpu overheating, but in their case the computer wouldn't even boot and it was crashing during the self diagnostics, but it does fit the hard power off mine is doing.

I won't be able to mess with it again until Saturday so I am hoping I can get some advice on what to try next.
