i5-2500K crashes on ordinary use

[chrispycrunch]

For years, my system was stable but in the last month it crashes under specific cases.

I have an i-5 2500K overclocked to 105x 4 (4.2Ghz). O/C never had a problem until now.
1) I opened chrome + website that loaded a 360 view of a car on nissan.ca. 5-6 tabs open maximum.
2) foobar playing music concurently.

Computer crashed and froze. How should I diagnose the problem? If it still crashes after returning to stock speed how do I troubleshoot?

Crashed under Windows 10 and 2) updated to creators update and still random crashes.

I also ran a crystalmark benchmark. When it got to the graphics card (which is integrated) testing, the computer froze.

What are the temps like ?

It sounds like a temperature issue. How long has it been since you last replaced the thermal and cleaned the case?

You can also try booting up on safe mode and see if it still crashes, just to eliminate possible software conflicts, though it doesn't seem like it. It can't hurt to check.

I was thinking the same thing - clean out the computer real well, including the fans, CPU coolers, and reapplying the thermal paste.

Hope this helps.
