Windows crashes on startup only when powering on system

I believe Tcase is 62°C. If you are using coretemp to read temps, they are reading the core temps. Core temps tend to be 5-10°C higher than Tcase. But the CPU has thermal throttling which will make it shut itself down if it gets too hot before any damage (but I don't trust that). But, if core temp is reading 65°C you should be OK. Personally, I tend to be more conservative than others and would shut it down around 68°. You may consider a little better cooler. There are several that are better than the stock one for 20-$25.

That's great news. I hope it keeps working well for you.

Glad to hear the Prime95 torture test passed.
You should be good and not get any more crashes, if there are any issues just post back here, we will all get a notice.
If there are any other issues the settings might need a little tweaking, hopefully you are all set.

Since your two systems are basically identical, the same settings should work on yours.


Those CPU core temps are a bit high, AMD CPUs normally run cool, so this does indicate a cooling issue.

Can you give us the CPU idle and room temperatures?
Your CPU idle temps should be at most a couple °C above ambient temps.

essenbe is right, a rated CPU temp of 62°C is for Tcase, you add 5°C for core temps, this makes the recommended max core temp 67°C.
I tend to be a bit cautious when it comes to component temps, heat + electronics = trouble.

Staying under this temp, the temps you had, is acceptable but, as mentioned this is a high temp for an AMD CPU.

Monitor the CPU temps when stressing the system, playing games is a good test, they should be max in the high 40's.
Have seen many AMD CPUs run Prime95 in the mid 40's.

Check that the CPU cooler is firmly attached, if you need to take it off it is best to clean and then re-apply the thermal paste.

Most people here prefer artic silver 5.

+1 on the Artic Silver. Very good stuff.
MAx temp is 62°C, 143.6°F

MelancholyRose, If you are having temps like that, i would recommend a third party cooler. If you are not going to seriously overclock, you don't need to spend a fortune on one. Just buy something better than the stock cooler. It is no secert that both AMD and Intel put out some not so good stock coolers. Install it right and apply the thermal paste right, you will see a big difference, in temps as well as noise.

Agree with essenbe AS5 is good.

That idle temp is way too high.
It will cool down fast after being under load, several seconds usually, a re-start won't help.

You need to get some new thermal paste, should be able to get AS5 just about anywhere, and clean the cooler and CPU, re-apply the thermal paste and re-seat the cooler.
Too much paste is not good, it can make the temps worse.

Read the 80 Thermal Pastes Tested, it is really good information.
You don't have to read the entire article, any paste on the last page Final Thoughts and Conclusion will do the job, if you can't find AS5.

Read the Application on HDT Coolers page, fill the gaps if your cooler has any, if in doubt use less rather than more.

I use the finger spread method, using plastic film (saran wrap) on my finger, to get a even very thin layer. It should be almost transparent, you are filling tiny holes in the metal, not making a layer of paste between the two metal surfaces.

If after applying the new paste and re-seating the cooler, you see any paste coming out on the sides, you put too much.

In a perfect world, no paste would be necessary, the above link will explain things.
