Hi everyone, I finally built my first computer this weekend. It's going great, but I'm having problems turning it off (not just because I can't stop playing with it). When I hit shut down on the start menu it shuts down, only for it to restart a few seconds later. If I hold the power button when it starts restarting then it turns off. Not a huge problem but kind of niggling. I wondered if anyone could help? I know I could flash the BIOS but I'd like to leave that as a last option ideally... Here's my build: Mobo: GA-Z68MA-D2H-B3 CPU: Intel i5 2500k RAM: Kingston HyperX Blu 8gb HDD: Samsung Spintpoint F3 1tb OS: Windows 7 Home Premium 64-Bit PSU: OCZ ZS Series 550w Here's what I've tried so far: Updated the BIOS to f9 Updated all drivers Reset CMOS (removed battery for an hour) Checked power options Disconnected network cable/usbs Completely at a loss now, hoped you could help! Dropped £90 on this mobo and can't return it, so if there's any fix to this annoying problem it'd be great. Thanks!
