Hi, The first of all, i need to say that my EXP GDC Beast V8.3E works perfect the 3 first days. The problem start when i turn on my computer and i saw that the monitor is not turned on, i check the device manager and i saw that (HORROR) code 43 .My first idea was to unistall it from the device manager and it will fix it, NOPE. Nowadays i try ALL that i can imagine and found on internet*, i dont realy know what is the problem, the first days works PERFECT i realy think that i have the best i
