This only happens 10-20% of the time, which makes it tough for me to analyze.
Basically, when I try to wake the PC from sleep or try to boot shortly after turning it off completely, nothing happens. Hardware starts for a fraction of a second and turns off again (as it would with power shut off).
On sleep, the Power LED continues blinking and I see a short flicker on my keyboard every time I press a key. Power or Reset button do nothing.
The problem usually goes away after taking the PC off power for 5+ minutes, but it still kinda bothers me.
Is there anything I can look into to see what's at fault here?
