Have had my OC stable with 9 hours of prime, 25 passes of LinX, and an hour of OCCT. But my system always seem to randomly crash when surfing the web, in the end i (with help from members on this forum) pinned it down to my memory and not being able to run at its rated speed, if i lowered the memory multiplier the problems would go away.....or so i though. Since sorting my OC out only over the last 3-5 days i have been using my system normally for day to day use(without doing all the stress testing stuff etc). But have started to notice a strange thing happening. This has happened everyday for the pass 3-4 days, when i turn my PC on first thing in the morning, or like today first thing from coming home from work, the PC shall boot up fine, login into windows without any problems, but within a couple of minutes the PC will just decide to restart itself with no warning what so ever!. This only seems to happen once a day and first time the PC has been turn on after being off all night. This has happened the last 2 days, and again today, the PC has then been on for the rest of the day (11-12 hours) and never does it again, its as if the PC doesnt like being cool, and once its warmed up everything if fine. Any ideas what would cause such a thing. I have noticed today, when i logged into windows in the task bar the 'Problem Reports and Solutions' icon popped up so i clicked on it and was greeted with the following window.... I have noticed the 'Problem Reports and Solutions' icon pop up a few time but always went away straight away, just wondering if its always listing this same problem. I downloaded the file, but when i went to run it it said there was already a newer version on my system. Would these 2 problems be linked???
