My monitor keeps saying "Frequency out of range" or would just completely shut down every time I browse on the net especially Facebook, YouTube, or just simply a news article. And playing games like Arma2 or sins of a solar empire. My computer still keeps running though. Pressing escape or ctrl alt delete does nothing and I would have to reboot manually. Some games that require a high amount of memory or refresh rate are fine though which baffles me. I bought my machine 2009 and its a gaming computer. My graphics card is an ATI radeon hd 4850, i7 CPU firstname.lastname@example.org ghz with 3 gb of ram. I never had problems before until now. I tried uninstalling/reinstalling the graphics card, checked if the software was updated, I opened it up to check for external damage on it or if it was loose, or if the motherboard somehow was fried but none of it seems to be the case. Checked all hdmi cables and connections and they were fine. Tried the driver cleaner pro as a last resort and that didn't work either. I've read from some folks that had the same problem had to replace their motherboard or computer. I really don't have the finances for a new one so I'm trying to do what I can for this one. Browsing the net on safemode sucks lol. Opinions anyone?
Tried that several times on different resolutions even to the minimum of 800x600 and still shuts downs. Recommended is 1680 x 1050. The only time it doesn't is when I'm on safe mode. I've never had this problem before. As I mentioned earlier I've been using that computer since 2009.
if you have another pc swap monitors..or plug the monitor that having issues into a laptop output and see if it shuts down. if it shuts down then the monitor is having power supply issue. if the desktop still having issue it could be the power supply or video card...try another video card first. also check to see if all the fans are moving and the pc not full of dust.
Tried that with an older, non-HD monitor and it still shuts down and along with everything else. I guess it's probably a video card issue but I have not tried replacing the video card yet. Will try that as soon as i can afford it and will post my findings.
