Screen Issues

While watching a video for a long time, I suddenly experience a system blackout and it's been going for a month now, what can I do about this?

After a through clening I seem to have lost the screen saver prompt. The program is there and working - but it does not turn on when directed. How do I rescue the code that seems to be lost?

All of my short cut icons on the Desktop are black. How do I fix that?

No me anda elbrillo, no lo puedo manejar a mi antojo, y los auruculares no los detecta.

When I turn on my pc,
after windows logo a blank screen comes for about 3-4 min.
then a "please wait" loop comes which lasts for about 1 min.

My PC: It's a prebuilt "ACER Veriton series."
