Hey guys, I’ve started having some issues with my PC after upgrading my CPU. My specs are as follows: Windows 10 Pro MSI 890FXA GD70 Motherboard AMD FX 6300 CPU using a Corsair Hydro Series H70 Core CPU Cooler Radeon R9 290x GPU 16GB DDR3 1600 G.Skill Ripjaws F3-12800CL9D RAM Okay, so a few days ago up upgraded my AMD Phenom II x4 965 CPU to the FX 6300 due to needing a CPU that supported SSE4.1 instruction sets for a couple of new games. I had to update the bios on my MOBO (to version 1.15) so it was compatible with AM3+ sockets (the MSI website says the CPU is compatible with my MOBO). Since installing the new CPU I have cleared my CMOS and now experience occasional system lock ups accompanied by an audible “RRRRRRRRRRRRR” sound if the speakers are on and occasional and random system restarts where the PC will spontaneously restart. I can’t seem to see a constant factor that is causing these issues as they happen at seemingly random times like playing games (although I have played MGS V for a solid 5 hours with no issues), to the computer downloading stuff overnight to the 2 times it locked up while writing this post and listening to some music on MusicBee. I have stress tested the CPU for 12 hours on both the simple and torture tests on Prime95 with no errors, the CPU’s temp also never got above 40 degrees Celsius. Which brings me to a side question, I’m using Open Hardware Monitor to check CPU temps and at the moment it is telling me that the CPU is sitting at 8 degrees Celsius. But, if I used Aida64 the temp reading is 25 degrees. Has anyone had this type of temp discrepancy with Open Hardware Monitor before? Moving on from that, the CPU is not overclocked, it is sitting on its factory 3.5Ghz and no other component in my system is overclocked either. I have check the systems even log, Window logs / System and there are a few warning and error titles there, although I do not know how to interpret them. Has anyone got any suggestions on what my next step could be? A friend suggested updating the chipset on my MOBO as there may be a communication issue with the CPU and MOBO due to the age difference but I can’t seem to find any info on the MSI website regarding updating the chipset. Thanks in advance, if I’ve forgotten any important info please let me know.
