Hello,

I've been having some problems with the brightness of my desktop PC. I'm not very well-versed in IT but I'll do my best to explain the situation and symptoms.

When I boot up the PC the screen appear to be ok for a second and then it darkens noticeably. Fiddling with the brightness controls on the monitor and the video card allow me to use the PC normally most of the time for regular applications like Word or Excel, albeit with most of the brightness settings maxed out.

The problem is more noticeable when I try to watch videos. I use BS Player and since I started having the problems two things happen:

1. When I go to the brightness controller on BS Player I see that there are no longer any increments on the slider. I can move it to wherever I like on the slider, and it remains there, but there are none of the increments marked as on the Contrast and other settings. If I slide it up full, the screen whites out as you'd expect.

2. After setting the brightness to a watchable level using the slider on the BS Player slider control, I can watch normally. However, at a certain point, usually when I resize the video screen, switch to full screen or back, start a video or something, the brightness will drop to zero again. When I go back to the video settings I see that it's reset itself to zero on that slider. This doesn't happen every time I resize the video screen or whatever, but perhaps one time in five - enough to be annoying.

The major problem occurs when I want to watch something like YouTube, which doesn't have its own independant brightness controls. In this case, I end up just having to watch it in relative darkness, or the best I can get it by maxing out the GPU and monitor controls.

I'm using XP, GeForce5200, AOC Spectrum 7Vlr CRT monitor. Let me know if you need to know anything else.

Thanks in advance for any suggestions!
