So I build my PC more than a week ago, and since then I have only had bad luck. My GPU has coil whine, had to RMA that, didn't apply thermal paste right, reapplied it, thought/think my WD Black is gonna die on me and now I'm really taking the piss. So I thought I'm gonna stress test the CPU and memory with Prime95. So I did Torture Test and then Blend. So I left it for 4 hours. Then after coming back to my PC after 2 hours and checking the PC was already acting pretty slow, but I thought that's probably because the processor is using all it's power in the Torture Test so I left it for the other 2 hours. And when I came back I moved my mouse so the screen would show up because it turned black but it wouldn't, so I was like what's going on?? So after like 3 minutes my PC decided to turn on the screen so it did, it was black with only the mouse, I was no not this again because this happened before. But then after a few minutes the whole screen showed up again but the mouse wouldn't move really, it moved every 5 seconds or so and after trying to stop Prime95 and the screen going black and back (ha) I decided to turn the PC off. So any idea why this is happening to me? You would think a 4790K would be able to handle this.

Did you monitor your temps throughout the test? If so what were they? If not, what cooler are you using, and then also rerun the test and monitor your temps. This seems like thermal throttling.

Well I did check it after the 2 hour mark and I was actually really impressed. Before reapplying Thermal Paste I had like 75 degrees Celcius and now I got 66 degrees Celcius. I can try it again if you want and try to check CPUID HWMonitor more often while it's proccesing. Also in the results log it stopped at 2:16 AM for some reason and I checked at 3:05 AM and that's when the next and last result came in, which is an hour apart. Why it stopped I really don't know. All results passed with no errors.

Temps are actually not fine, and CPU's shouldn't REALLY go over 65c-70c, as they will start to do preventative measures to stop any damage. Like throttling... and shutting down.... :-/

Really? I heard the 4790K stays around 70 degrees under load. Some people experienced 100 degrees under load and no shut down. And I have Seasonic G-Serie 650W Gold Plus Certified. You're actually not the first one to say this about the coil whine. The PSU it self makes almost no sound at all and seemed pretty good to me but is there a way to check and trying with another PSU isn't really an option to be honest.

Well temps SHOULDN'T go past 70c but people still do it, at risk of failiure or even wrecking it.

those temp are fine .. as long as you keep under 85 is safe ... throttling is 100c ... every one OC in here and their temp in stress is 70-80 are normal ( tress test is normal)

I'm OC 4790k to 4.5 right now and my temp is 82c in OCCT small ( they hotter than prime95) and i'm happy with that :).. i might go back down to 4.4 but under 80 is great on this cpu

Downloaded it and these are 2 crashes that happened yesterday:

On Sun 27-7-2014 14:33:06 GMT your computer crashed
crash dump file: C:\Windows\Minidump\072714-4718-01.dmp

Catalyst? But I don't have a AMD GPU installed right now. And I have the Beta, think it was 14.7. I'll install the non beta version.

Well it's saying in the description there that the problem for the first crash was deeply rooting into system32. Which is where most of your operating system lies. What i'm wondering, is did you delete ANY files in System32?

Yes a file called keygen that Windows Defender wanted me to delete.

I said in the beginning that I returned my GPU.

I actually use the Integrated Graphics in my 4790K hahaha. I can't really game much but I can play stuff like FIFA 14 on high and Trials Fusion on low but other than that not much. I got max 30 fps everything low on bf4. I have to wait until they send me another one. Lucky for me Club3D is located in The Netherlands, where I live, so I hope it doesn't take like a month.

Eeeekkkk.... I would never delete anything in System32. Ever heard of the troll people do to little kids? They say "If you delete system32 you get 4GB more RAM and faster CPU." Someone some people still fall for it..... Not saying you did, but the reason why it's a troll is because disrupting the system32 file causes crashing, a needed reinstall of the whole OS, or even bricking. :-(
