I have a pretty unusual 'Out of Range' error, unlike most that come up on Google. It's not my monitor settings or anything like that, there's definitely a hardware issue. I'm completely unable to look at pictures on my desktop, I can't open video files or anything, can't play games, but for some reason, when I do all of the above in a browser, like Firefox, I'm able to. If I download a .gif or a .jpeg file, and I go to view it with Windows Picture Viewer, I immediately black screen and my monitor says 'Out of Range'. Sometimes if I hit a button, or push in the power button, I get a weird and annoying noise. I'll also get the crash sometimes when I'm just regularly browsing the web for an hour or two. I'll load up a page with a crapton of images, and it'll just crash. After rebooting, I can load up the same page just fine. Sometimes, there are certain elements on a page that will crash me every time I go to it. Because of that fact, I haven't been able to determine what it is, but some pages I have to just completely avoid. My question is: What hardware issue is likely causing this. This is the prebuilt rig I'm using. (HD4850 Series GFX Card) My dilemma is that my car broke down, and I need to buy a new car, so I don't want to go poking around in my comp unless I really have to. If I lose my computer, I won't be able to buy another one for a couple of months, so I have to play it carefully. That being said, I've read some stuff about my particular computer having an issue with the fan on the GFX card dying. If that's the case, would the fan sensor still be working in GPU-Z? My GPU-Z reports that my GPU temperature is almost always consistently idling around 60c, which is very high, I realize. It seems pretty clear that it's my GPU, but I want to be absolutely, positively certain. For a while I was convinced it was my PSU, then my friend said it could possibly be my Mobo. Thanks!
