Hi guys,

I am new to this thread and unsure if this is even the right place for this but here goes.
Just built first home build today in including
asrock motherboard,
quad core AMD,
650W case with large fan
Radeon HD 5450 VIDEO also using Full HD tv as monitor

Was working perfect for about 5 hours, when during watching a documentary streaming at 720p switched off never to switch on again.
The light at the back of the PSU is fine which tells me that is ok. but when i press power or reboot nothink is happening, no fans or drive...nothing.

what happened?

I put all spacers in case perfectly so not that motherboard touched case, i have taken it all apart and looked at mother board has no visable signs of any damage.

Also temperature stayed very good all the five hours as i was monitoring it from desc top program and by feeling for warm air at the back,

Test the power supply on another computer first, then if it works fine, RMA the motherboard.

If you plugged your case fans directly into the power supply, and even they won't turn on, it's probably the power supply.

I've had bad power supplies power fans up, but not have enough in them to power systems, so that method may or may not work. Also, if you are trying to jumpstart your power supply while it's not in a case, short the green wire and any black wire.

Yeah, but I'm saying that if the fans don't turn, then it's probably the PSU.

When this happens to me I try unplugging the 8 or 4 pin connector, then the PCI-E connector. Once when I came across a non-booter it was a faulty board and PSU. Another time it was a blown graphics card VRM (removing the PCI-E connector made the system boot). Another time it was a blown motherboard/CPU VRM (unplugging the 4 pin made the system boot).

Sounds to me like a killed VRM.

What was your power supply? If it's a cheapo one, that's probably why.

EDIT: Oh god, just saw "light at the back of the PSU", a Bestec by any chance?

ok so going to try and find the source of this problem before writing letters back to the company as i have bought the parts from different vendors its not as simple as just bringing it back.
Can anyone tell me if the motherboard where fryed would the fans and drives still switch on, even just a few blinking lights?
this would mean that it is just simply something small like that actual power switch at the front is faulty.
but it the motherboard was and the power switch at the front is connected to it then maybe the drives would not even flick on...
arrrrgg...

The ipotetic scenario for your problem is that the cheap Power Supply you first bought couldn t get the load ,then it fryed itself taking the mobo with it (or maybe more components).
Or the mobo died taking the PSU with it

Either way thats why a Power Supply needs to be from a good brand ALWAYS, to turn off without overvolting the connected items no matter the cause.
RMA the mobo and CHOOSE PSU WISE!
You will need now to RMA all if the mobo replacement will bring no joy.

Check your ram is seated properly and is in the correct matching slots.
