About two weeks ago, my friend helped me with installing Windows 8 operating system on my computer. And I have not found any problem since its installation until last evening. I found that the screen savers not working even though I kept the computer alone for a long time. But it had been working well before Windows 8 installation. And there is a prompt message to indicate me to update the video card driver.
What shall I do? Pls do me a favor!
Thanks a lot!
