What is causing these random restarts?
You are troubleshooting a user's computer who has just recently upgraded their video card and now it just reboots at random times. You ask the user to keep track of when they notice the reboots happening. After a day, the user reports that it happens when they start up a game or when they start streaming hi-definition video.
A. The graphics card they upgraded with is not on the HCL B. They have a corrupt graphics card driver C. The video card needs a more powerful power supply D. The game and video streaming applications are incompatible with the video card
The video card needs a more powerful power supply-correct answer:
the video card needs a more powerful power supply. it sounds like only when the user is pushing their computer with complex graphics processing that it is running out of power and simply quits. upgrading the psu would most likely resolve this issue and give the graphics card all the energy it needs.
the graphics card is not on the hardware compatbility list (hcl) couldnt be it because it seems like they only have the problem when there are doing intense applications. all the other times the video card is doing fine.
a corrupt graphics driver would most likely make the image on the screen disfigured, blurry, discolored, wavy lines, etc.
if you have video card drivers installed, then your system should be able to play a streaming video or play a game without having to worry about compatibility issues. now, having said that, depending on the graphics card you purchased, your performance can be greatly effected in video playback and esspecially gaming.
