Pc overheating all of a sudden? Freezes with buzzing sound??

[TheSinglePringle]

I haven't changed anything in my rig and all of a sudden I can't play intensive programs for more than an hour to two hours without my pc freezing with a loud buzzing sound. I just ran furmark and prime 95 and I wasn't willing to let the run for even 5 min! My cpu hit 90C within 2 minutes as well as my gpu! What is going on? I just dusted out my whole case with compressed air and the temps are still bad. This hasn't happened before but has slowly gotten worse. My cpu idles around mid 30'sC and my gpu idles in high 20'sC. Any ideas??

use this on the sensor page and report result http://www.hwinfo.com/download.php also what kind of air flow you have in the system how many fans as intake and outlet and does you psu push air in the case .

Prime 95 is a horrible cpu benchmark for haswell cpus, try adata or other cpu burn tests. What cooler you have installed? Those seem like reasonable temps for a naturally hot cpu.

The idle temps aren't bad, especially for the gpu. It shouldn't be hitting 90c on the cpu though, that is bad. Any chance you bumped the cooler loose while cleaning it? I'd get some thermal paste if you don't have any on hand, remove the cooler and clean both the cpu ihs (metal exposed surface) and the cooler base using alcohol. Clean off all the old compound, apply new and reinstall the cooler and see what it reads.

The haswell isn't that hot. My concern is the op said they didn't change anything other than cleaning the pc. I've got a 4690k haswell (devil's canyon) running 4.2 and highest it hit was 69c under prime 95 v26.6 (the version suggested to use with haswell) and the small fft's. It ran for half an hour like that cooled with nothing more than a cm hyper 212 evo. The 4770k isn't that much hotter than the 4690k.

I don't know why my ram read to be at 666mhz. I had it set to 2000mhz (its base clock speed). I have 4 fans, two on the side one if front pulling and one in the back pushing. I have one fan pulling that is a gpu cooling fan on the door and the other fan on the side door is pushing ( The pushing one is level with my cpu) My heatsink is the stock one.

When you dusted off your motherboard, did you remove the cpu cooler and re apply thermal paste as well? If so, make sure that the cooler is properly seated for maximum cooling. Also if you did this, make sure you did not add too much thermal paste. Too much can insulate instead of dissipating the heat.

One last thing you can look at is the miniscule dust on the board surrounding the CPU area. Sometimes a sensor can have a little bit of dust on it that drives the temp reading through the roof. I just went through this myself a few months ago with my old parts. I had a Phenom II x6 that never had any problems reaching 4.2ghz, but as time went on I saw higher temps and more instability. At first I just figured the chip was losing steam and couldn't handle the clocks anymore. I kept lowering my clock speeds, and voltages until I could only stabilize at 3.8ghz. I keep my computer very clean, but temps kept rising. So right before my new parts showed up I decided to try something different. I used 99% isoprophyl alcohol and a cotton swab to clean the board area all around the CPU. After doing so, my CPU temps dropped back to where it originally was and I was able to clock back up to 4.2ghz again. I honestly couldn't believe that the light layer of dust that the compressed air didn't get out would cause that much of a temperature variance. Once my CPU temp reading hit 65c the motherboard would shut down to protect itself I guess. After that bit of dust was gone I wouldn't even hit 60c at 4.2ghz. It made a big difference.

I know! Like I said I didn't change anything but I have noticed that I have slowly been getting more and more freezes with these buzzing sounds. And I won't have them for a bit but then for a couple days I'll get then daily for like a week.

Nah, I didn't remove anything from the mother board. I am going to buy some thermal paste either today or tomorrow and see if that changes the temps. And I don't think it's dust because if the reading were false my pc wouldn't be freezing up. Unless the freezing is another issue but I doubt that is the case. Thanks for the ideas keep them coming!

front and side should take air in and the back and top push hot air out the memory at 666x2= 1332 that the real speed she run and what are the temp fan speed and voltages hwinfo report the buzzing sound could be a fan or the psu even a coil on the motherboard .

The gpu fans are both running at 1100 Rpms and the cpu fans is at 1600 Rpms. The average gpu core voltage is .850v and all the cpu cores are hovering around .800v.

 

[scout_03]

then the voltages are good if you could get mx2 or mx4 as cooling paste they do not need cure time and try to unplug one fan at the time in the case to see if buzzing come from them and it could be the psu ot the psu itself .

Oh sorry I didn't explain the buzzing to well. The buzzing comes from my speakers when the pc freezes. It's super loud and will sit on the same screen until I hard shutdown and will make a loud buzzing sound. Exactly like this https://www.youtube.com/watch?v=HT3nGYHokSc#t=219

this is a laptop and gpu could not stand game try to play at lower settings .

I was just quoting the sound haha, I've been able to play intensive games like bf4 on ultra for the past year or so and just these past 2-3 months I have been getting these freezes. I just don't know why it keeps getting hotter and hotter, faster and faster.

 

[synphul]

Someone mentioned laptop but it sounds like we're talking about a pc - is it a pc? Also, cpu cores are hovering around .08v - which sounds about right if it's throttled down idling (no load, not throttled due to heat) - and yet the cpu fan is at 1600rpms? That sounds awfully fast for a fan on an idling cpu or at least a cpu running that low of voltage. The fan wouldn't crank up unless there was a heat issue (or a sensor was indicating enough of a temp threshold to require a faster fan profile).

its a desktop, and your speculation is correct, i think i read here that he has a 3pin on a 4 pin header. But whats with the freezes and the sound?

 

[synphul]

Oh ok, a 3pin fan on a 4 pin header might make it run at fixed full speed. It sounds strange with the sudden overheating and screeching sounds. The freezing/screeching could be due to the heating, electronics flake out when they get hot.

TheSinglePringle, any chance you can try running the game and see what your temps look like during gameplay? I know you said they were normal at idle, they went bonkers under stress testing but it would be interesting to see if the temps are way up during gaming as well (you mentioned playing programs for awhile, assumed you meant games).
