No Power

Specs: Windows XP
Hey Guys,

Got an amber blinking power light and no activity. There's a solid amber light on the motherboard. I tried the paperclip test on the PSU and the fan started up so it's looking increasingly like the motherboard i think.

The strange bit i can't seem to get is that every 10 minutes or so of sitting with the power cable in but not going on it will try and start up but fail after about 2 seconds. Earlier when i tried holding the power button down for 20s whilst unplugged when i plugged it in again it did try to start up - that hasn't happened again tho.

So is this definitely a motherboard issue? Is there anyway to test for sure? And if so do do i have to get the exact replacement or can i buy a different motherboard?

Thanks!

If you`re sure the PSU is OK, it`s possible to be the Motherboard or CPU.....

If possible, test each of them before you buy either.....and try to boot with CPU, RAM and GPU only....

To be honest i posted as i'm not 100% certain it isn't the PSU. Found on another forum where the paper clip test worked and it was still the PSU causing the problem.

How do i test the motherboard to see if is working?

um....what about testing your current PSU ?

if it turns out your current PSU is OK, you`ll have to sell / throw the new one...

I am glad it`s fine now & you didn`t have hard time with testing the MoBo / CPU...

Be aware that a bad PSU can kill your whole system....just a tip if you have troubles similar to this again ( knock in wood )...

Cheaper PSU will die faster.....besides that, it can kill the your whole system.....better spend more --- it will last longer and probably won`t kill your system, but IT`S POSSIBLE...

That PSU cost about $24 US. That is low end stuff. I am amazed at how little information is supplied on UK hardware sites. The full specs on that PSU are no better than the ad.

I don't deal with any site that won't give full specs on hardware or at least a manufacturer's link. When I have found those links they STILL don't have any specs. How can a manufacturer not have the specs of a product they make?

Forgive my rant. The point of it is that you really have no clue of what Amperage is being provided on any of the rails in your PSU. Without that info it is impossible to make an intelligent buying decision.

BTW, if you have an add in graphics card and/or additional drives the PSU is most likely undersized.
