Okay so the title pretty much explains everything.
I'm having the same problem as this guy: (http://answers.microsoft.com/en-us/windows/forum/windows_7-system/multi-colored-lines-appear-after-booting-up-pc/6236afec-969e-40e1-b0df-abbc520f772d) after REINSTALLING windows 8.1 . On the first install I only had screen flicker, this time its with the multicolored static. On the Dell Factory OS (Windows 7) Never had this problem. Just a dark area on the lower right part of the screen. This laptop is 4 years old. And i'm a power user. What should I do? I tried reinstalling video drivers from dell, and it still happens. Should I try Intel and Nvidia's drivers? I have an Intel HD 3000 and a Nvidia GT 525M.
EDIT: Is my video hardware failing? This is scary.
