PhotoRepair

anyone any ideas?

Brilliant! My computer shop for years and years

My i5 3470 rig randomly goes through the reboot procedure without rebooting. The "Boot sound" beep sounds and the fans all whir up to 100% fora few seconds and it all settles down. It does not affect me in any way but it is troubling why it is doing this. I dont do much other than photoshop. At best i'll have chrome open with 4 or 5 tabs, photoshop and nothing else. Chrystal Disk says all my discs are fine, what could be happening? Any clues or help would be most welcome. Windows 10 650 Watt PSU 32GB Ram Stock cooler (no over clock) Gigabyte z77 D3H Mobo
