Since June, I've been getting random crashes, the cursor freezes up and I have to hold down the power button to restart, after a restart there's no issue. These occur once per day every 12 days or so.

3 weeks ago I ran and passed memtest86. Did a Prime95 blend test for couple of hours temps got to max 80c. After another crash this morning (system auto restarted) I decided to run Prime95 with small fft, it crashed within 6 minutes temps were about 65c. System crashed again on restart. I gave the case a clean, since then its been stable for the past 30 minutes.

Not doing anything resource intensive during the crashes just web browsing.
