Smell the PSU.....Those symptoms are normally psu...
All the best Brett
Re-applying thermal paste might be a wise move too.
Thanks for the post. I searched CPU thermal meltdown and found this thread. In my case the fan was turning, but turning too slowly. Checking temps in the BIOS I was over 75 C. Fan wasn't moving much air. Swapped fans and I"m at 43 C overclocked. :P
Posting this for anyone else that comes along. Interested to hear how you resolved your issue though.
Thanks again. Thanks all.
Be real, be sober.
A strong acidic smell is usually caused from a blown PSU. If you have an extra PSU or know someone who does switch it out and see if it works.
