My computer started random rebooting by itseft ~ a week ago. Then it started to reboot more and more often, no matter gaming or surfing, watching videos, etc. It always works after first start either random amount of time, or ~30 minutes. After then it reboots, shows Gigabyte DualBIOS string with an empty blue-colored page, and, when I move mouse, cursor location becomes black rectangle in the right middle of the screen. Then it may boot normally, but reboot after 5 to 30 minutes, or reboot immediately, and freeze. Such a freeze, so it doesn't even shows a picture, monitor's power indicator becomes yellow - like power is on, but computer isn't (power saving mode), but all fans are spinning normally, and their noise level isn't different from usual load process time. I haven't a speaker installed, but it seems like my mobo is crying about POST errors.
I tested with Memtest86+, no errors is found, just reboot after that 30 minutes. Changing RAM configuration (remove one stick, swap their places) solved the problem for a first day, then for ~5-6 hours, but then I got reboot. So it isn't Windows problem, as even at Memtest system reboots. At first, i thout that something is overheating. But it's 14C in my city, maybe 18-19C in my flat, while no problems have been before, when temperatures was around 29-30C in flat, also it's being cleaned of dust regullary. My PSU is only 4.5 months old, bought with new mobo and CPU. It's a Cougar PowerX 700, FX 8350 and Gigabyte GA-970A-UD3P, also my graphics card is Radeon HD 6850. FX-8350 heats up maximum to 56C both socket and core after 15 minutes Linpack test on 8 cores. Maybe that is power surges or everything wrong because there is bad power source? Video card doesn't reach even 68C. So what is that problem and how I can fix it?
PS: I already reset my BIOS - no changes
