EPTedit: Actually it seems the issue is pretty widespread. Massive overvolting specifically with any LLC, as much as 0.05-0.15vcore (so for example 1.2 to 1.25-1.35) so i would really just avoid all asrock boards (atleast z77) until at least there is more light on the issue

I was reading something about a ground loop. If this is the case 1) How do I know for sure that's what it is, and 2) how do I fix it? Computer connected how to receiver? HDMI, coax S/PDIF, optical S/PDIF, analog? You can lift the ground plug on one of the devices, but that's not exactly proper with respect to safety. Try plugging stuff into different outlets. | ||

While I had my case open, I figured I'd vacuum out some of the dust that had accumulated. Got everything back together, hit the power button, it booted into Windows normally, and then shut off abruptly about 30 seconds later, as if the power had been cut. After this happened again, I realized that I probably didn't reseat the CPU heatsink properly and it was overheating. (There was a ton of dust in it, so I took the whole thing off to blow it out). But okay, we can fix that. Open it up, finally get the thing clicked into place (stock Intel 775 -- which apparently are notoriously difficult to install sometimes), try again. Uh-oh. Worse than before. It shuts off abruptly before the OS even loads, but at least it does POST. In hindsight, I shouldn't have taken the whole heatsink off. Now, after an hour or two of frustratedly checking connections and reseating components, it doesn't boot at all. No post, no video output of any kind, with either video card in either PCI slot. Neither my case nor motherboard have speakers, so I can't listen for error code beeps. When I hit the power button, all the lights and fans come on, I'm pretty sure the hard drives are spinning up, but I've just got a black screen, and it still shuts off without warning after 1-2 minutes. I can manually shut it down by holding the power button in the meantime. Finally, something else I overlooked occurred to me just now. When I reseated the heatsink, I disrupted the original stock thermal paste, and don't have any of my own to replace it with. Maybe the CPU is still overheating? I'll go get some tomorrow, but in the meantime, could I have permanently damaged anything by trying to boot it up with the old paste? It's 5-6 years old. Ugh. I don't really know what else could be wrong other than the machine shutting itself down to protect against overheating, since nothing else has changed from 8 hours ago, but if that were all it was I would think I'd still get video output. | ||

You might've damaged something when you went "vacuuming" inside your case. From an outside perspective it sounds to me like Even if its not the PSU causing the initial problem 1, the latter part could still be the issue. I'd methodically go through all your parts and motherboard making sure everything is actually plugged in and is actually plugged in correctly. Don't neglect the little front panel pins. Try going down to the very minimal amount of things plugged in and work from there (unplug extra drives, opticals, etc.) | ||

Thermal paste comparison: http://www.hardwaresecrets.com/imageview.php?image=43088 It shows most work is still done by the actual metal of the heatsink and cpu touching. Though the thermal compounds do a lot to help, it'll still be enough to get everything working even with nothing. The cpu can't overheat without load, so Windows at least should boot. (the picture is from this article: http://www.hardwaresecrets.com/article/Thermal-Compound-Roundup-February-2012/1490/4) | ||

I'll keep trying to check all the basics and see if anything happens. My system at least seems "stable" for now, i.e. it doesn't power itself off within a few minutes anymore, but still no output to the monitor. I can tell it isn't just booting into Windows normally with me not being able to see it on screen because my keyboard lights never come on. Pretty much any modern CPU comes with built-in protections against overheating. I'm sure you could still damage them, but these days I think it happens more with over-volting than it would from overheating. | ||

What monitor size pros are using? What monitor you could suggest? (not cheap but and not very expensive) | ||

Hey all, just started playing on the new SC2 patch. Every game at some point the screen just gets black, tabs to desktop and sometimes tabs back in to SC2, sometimes crashes completely. Anyone know how to fix this? Would really like if at least someone could look at this, seriously ruining my SC2  | ||

When I reseated the heatsink, I disrupted the original stock thermal paste, and don't have any of my own to replace it with. Both of these are pretty big red flags Sirex, i would suggest 21-22" 1920x1080, all tournaments, streams etc use it and that probably wont change any time soon | ||

In other forums i saw people talking that 27" is better for gaming but i am afraid it could be too big for me and for SC. What monitor size pros are using? What monitor you could suggest? (not cheap but and not very expensive) I think 24" are considered the best "large" monitor for gaming since beyond that you start getting into higher input / response times. That said, I've got a Dell U2713HM (27") and I'm quite pleased with it. You need a system capable of running at 2560x1440 if you opt for one (though there are 1080 27" monitors iirc), so be sure your system will be able to handle the increased demand. I think you'd be fine with a 1080 24", though. FWIW, my monitor distance is roughly the same as the length from elbow to finger tip (~20 inches). | ||
