PC doesn't respond to power button

[Matt1258]

Hi
When pressing the power button nothing happens. Fans don't move, no lights come on. When using the cmos pins to clear it the fans move for a second and then stop. I've tried stripping it to bare minimum but no luck. Is it the motherboard or the CPU that died ? I don't have an option to borrow a psu to test it so I'll need to buy one.


Core i5 2500k
ASRock Z77 Pro4
12GB Corsair Vengeance
KFA2 GeForce GTX 970
Samsung SSD 830 128GB + Samsung F3 1TB
Asus Xonar DG
Antec vp550p

Just supposing this is a new build, here are some thoughts (which may lead to an answer):
- review motherboard manual and confirm connections are correct...any change?
- remove connection to power button and short the pins...did it start?
- remove everything from case and do a benchtop build...adding one or two components at a time....did you get beep codes?...were they the right error for the state of construction? (ie, CPU is installed but no RAM, you should get a RAM error, etc)

If this is an old system which stopped running, then I would say either a bad power button, bad or loose RAM or PSU. I keep a spare PSU on the shelf just for these types of problems.

Call Antec and see if any warrenty is left on it before you chuck it.
I had a vp450 and it lasted for 2 years, it just quietly died out without any warning.
