So lately I've been getting random crashes on my pc. Since it started I did a fresh install of windows, and I am sure it is not a psu problem, I have been monitoring voltages and such. PC is well cooled and fairly dust free. Could it be a mobo problem? Also ran the windows memory diagnostics and no problems there... Usually crashes when there is little load on it, like watching youtube, or browsing; but I can leave it for hours just installing games off steam with no problems. Its running a MSI 970A g43 mobo, fx 6300 no oc, and a r7 260x gpu, and a seagate 1 tb ST1000dm003 hdd and a evga 600b psu and team elite 8gb ram.
