CPU: AMD Bulldozer FX 8120 (1 year old)
RAM: G.Skill RipJaws 1x4GB 1333 (2 years old)
GPU: XFX HD 6850 (2 years old)
MOBO: ASUS AM3+ Asrock Extreme3 (1 year old)
PSU: Corsair GS 700W 80+ (2-3 years old)

1. Whenever I try to wake it up or turn on, it will usually just go sort of idle, nothing's going to pop up, just blank screen with message that there is no HDMI source. I was trying to reconnect cables and all that, nothing worked but turning off the PSU and turning it back on again after 1 second delay, then the PC will start normally.

2. From time to time the keyboard and mouse will randomly start disconnecting for a split second and that goes on for about a minute.

3. Sometimes when I start a game, it will restart after 2-10 minutes.

My guess is that it's the PSU, but I'm not sure. Please let me know what you think.
