I've been dealing with this issue for a while. I'll reference my previous posts below. I've waiting so long to post this partly because I was too busy to get to the root of the problem and partly I wanted to TRULY understand what seems to be causing it before I wasted people's time.
Those did fix some problems, but not the big issue that still seems to be bogging down my system.
So here's what I've discovered:
I have a LOT fewer issues viewing content from the Internet.
I sometimes go days without my PC doing the monitor, sound, keyboard/mouse freak out. When it does shut down on my, the sound generally keeps going. Occasionally I lose sound as well. Regardless the only way to recover is the power button.
This can sometimes be OK. On other days it is like 2 minutes and it goes down. No monitor, no sound, no mouse, no keyboard. It varies, but it seems like it happens sooner on network TV (CBS, ABC, etc...) than on the "others" ( i.e. CW). I can "Sometimes" watch recorded TV. Some days it is the only way to watch TV, some days it's just as bad.
I have tried using another monitor. The same thing happens.
One thing to mention, is that during start up, I briefly get a blue screen flash that says something about no support, then it flashes away and everything is peachy, until it does the "no support" thing on the monitor, and the other issues above occur. Another thing is I have seen some sort of video errors reported now and then, I don't really know what they mean or if they are a result of another problem. Any thoughts??? Thank you for reading this far! I look forward to solving this mystery!!
