I am using Firepro V4800 with Windows 7 64bit.
I bought the Firepro to replace a built-in video function, and I am sure that I installed the most recent video driver. I even removed other video driver existed previously.
The problem is that a display suddenly drops to a blank screen.
A LED indicator on my monitor went from blue to yellow, and a LED indicator on my keyboard was off. However, a power indicator on my desktop was still on, and all indicators on my mother board were still on.
In addition, I could not turn on my system right after the issue. I should try to reset my system several times. Sometimes it worked, and sometimes I should wait for several minutes.
Unfortunately, there is no apparent condition to this problem. This occured during surfing the Internet with FireFox or selecting files with built-in windows explorer. And this does not occur during playing games.
Therefore, I removed my Firepro V4800 from my system, then this has not happend until now.
Please I need your help.
