I have a Intel Core i7 system, ASRock MoBo, triple channel memory, EVGA graphics card.
This is a ~2 year old build, that have been running perfectly until now.
Whenever I turn it on, it turns off again within 20-30 seconds. Only once have I seen the ASRock bios splash screen appear.
I have tried to disconnect all drives, with no effect.
I don't know if the PC speaker is missing, but I wanted to see if it would beep when the memory or graphics card is missing - it never did, so don't know what's wrong.
Even if I keep hitting the reset button the stop it from starting boot, it still turns off after 20-30 seconds.
What do you think? Is it the PSU that fails?
