Help please. Power Surge problems, unable to boot

I've just put together my PC.
System Info:
Speccy:http://speccy.piriform.com/results/L6p5HeQqaXlW3RViB0iojDF

So far I've managed to boot it up, play games and have it run a whole session without crashing but its only when I shut it down completely, it 'powers on' momentarily and then restarts itself.

Sometimes the system remains powered on but the display fails to show.
After more than a few hard shut downs and hitting the I/O behind the powersupply, I'm able to get a message "Power supply surges detected during the previous power on. Asus anti-surge was triggered to protect system from unstable power supply, press F1"

I've just updated my BIOS yesterday and took me forever to get it to boot up again.
I'm now starting to find it real hard to get it to boot normally without doing short repetitive restarts right after pressing the power button.

So far i've done the following..
- Re-seated the ram chips.
- Re-seated the cables going into the PSU
- Unplugged the GPU/peripherals
- Connected the PC straight to the mains
- Updated BIOS
- Default settings on BIOS.
- Ran Memtest86 (Pass)
- Disabled the power surge detection in bios

Still getting bad boots.

When I'm eventually able to boot, everything seems to runs fine.
(Currently writing this message on the computer)

Not sure how to go about this..

Make sure the power settings in the BIOS equal the power state settings in windows.

In control panel there is a icon of a battery for power settings.

Customise it and what are the settings for when you press the power button?
 
Either a bad power supply, power strip, or you need a better surge protector/battery backup with AVR.

Sorry I forgot to mention I've got a Seasonic G series 550w Gold+
I've also gone in and disconnected the hard drive cables and added new ones to see if it were overloading issues.
Also tried fixing the I/O shield and making sure those bits sticking out were actually grounding properly.
Still getting bad boots.

While the hard drive are not attached then try booting from a USB device and or plug the DVD back in and try booting from the DVD.

If you see no physical damage and all obvious and not so obvious things were checked and it still not good then I would suspect the motherboard suffered static shock damage of some sorts.

Unfortunately the only way to check for static shock damage is by using a very expensive electron microscope which is the only tool that can see damage by electrical shock.


Other simple things you can do is put your face close to the motherboard and other electrical things and smell for any electrical burn.

If you do find anything that smells burnt then you found your culprit.
 
my apartment is floorboarded and my computer still turns on after a while.
could it really be static damage? 🙁
i've always wondered, how are you able to take the processor out if you were to replace the motherboard?

If it was static shock damage then I would say motherboard and cpu are bad and sometimes video card.

I would think hard drive could be ok. Used to be back in the day EMACHINE computers if they suffered any electric damage then the entire pc is no good.

So you might be able to salvage some parts.


Just remember to expel static build up by touching something with metal before you touch the computer.

Risk of static shock rises when weather changes to dry season.

Surge is a subjective term. It can be low voltage, high current, high voltage, low current, too much delay, or something too fast. Long before trying to fix it, first the problem must be defined.

Problem might be the motherboard reporting a failure on one of many components in the power 'system'. To say more requires numbers from a meter used with some requested instructions. That is what they mean by 'follow the evidence'.

Your only other alternative is to shotgun. Start replacing good parts until the problem no longer appears. Any part recommended by anyone is the best part to replace first.

If your computer is working as required, then incandescent lights can dim to 40% intensity. Even voltage that low is perfectly normal for any properly constructed computer. IOW ignore the myths about low voltage, dirty voltage, or some magic box UPS to solve power problems. If your lights are not dimming, then AC voltage is perfect for every PC.

Another useful tool is heat. A defective computer can work in a 70 degree F room. And fail in a 100 degree F room. Both are perfectly good temperatures for good computers. But computer defects are sometimes easier to locate when operating in a warmer room. The defect that only fails today at 100 degrees will probably also fail months or years later at 70 degrees.
 
Have you tried another location or any of the thoughts I mentioned above? What is the connection from the wall to the power outlet like?

Tested the PSU. Apparently it's fine.
The PC is connected to a power surge protector at the moment.
I'll try test the parts one by one now
 
Good news at last.
I think I may found the issue.
I removed the parts one by one and noticed the system didn't boot properly with the graphics card on.
I moved on and inserted a DVI and ran direct onboard graphics and everything worked fine.
I checked to see if the DVI worked on my graphics card and noticed it still booted fine.
So my conclusion was the brand new Display Port cable that I purchased a day I installed my computer.
I had another DP cable lying around thankfully and switched it over and so far no problems.
Knock on wood.
Will post back if anything happens.

Thanks for all the help everybody.
