I really need your assistance and I hope that you can help me.
I bought a new computer about 1 month ago (assembled it on my own, just bought all parts). For about 2 weeks there were no errors/bsods nothing it just ran perfectly. After these 2 weeks(or maybe 3 weeks idk) my computer began to crash sometimes with a bsod saying "pfn_list_corrupt". I googled it and I read that a possible cause could be my RAM. So I replaced my ram but nothing changed at all. I also scanned both ram kits (2x4gb corsair vengeance) with memtest86+ and both I got errors for both kits. it is a 1600 ram running at 1,5v so I looked up my bios settings and changed the ram voltage from 1.510V to 1.500V and scanned the ram again. And again errors were listed but at different points/tests.
I decided not to replace any more hardware but to just work as usual with my computer. Sometimes it runs for 2-3 days without any problems but sometimes it crashed every 5 minutes.
Now since about 3-4 days the behaviour got even worse. New bsods (system_exception, memory_management), more crashes and strange temperature sensor behaviour. Because of the warm weather here I started to watch how much hotter my system gets while doing some heavy work (prime95). So I started CpuID Hardwaremonitor and watched the cpu temperature. I noticed that the temperature fluctuates from 17 degrees celcius to 30 degress celsius in just 5-6 seconds. Sometimes the temperature shoots up to 30 D.C. and then it calms down to 16-17 D.C. and then it shoots up again.... Usually my cpu temperature was at about 28 D.C while idleing.
I started to use different OS (Win7, Win8, Linux Arch, Linux Kubunutu). The problems described above happended running W7. I wasn't able to install W8 because it started crashing while initializing hardware after installation. Until now I didn't notice any crashes under Linux Arch + Awesome window manager. Sometimes the X server crashes running Kubuntu.
I really don't know what happens to my computer. First I thought it is just the memory. Yesterday I thought the new errors could be caused by the heat but I think it is the mainboard (Gigabyte GA-970A-DS3). Are there maybe any hints in my description that can tell anyone of you what the problem is or what it could be? At the moment I can't go to a computer shop because our car is broken (maybe I can tomorrow) so I hope that someone here at SU can help me in the meanwhile.
Thanks in advance :)
P.S.: My hardware configuration:
AMD FX6300 6Core (not overclocked)
4x4GB Corsair Vengeance LP CML8GX3M2A1600C9
Palit Nvidia GeForce GTX660
Samsung 840 Series Basic SSD (120GB)
