Powering Problem (motherboard?)

[meddler66]

SO heres the problem: my computer wont power up, the light flicks every few hits of the power button and nothing, but than when i unplug the ethernet chord and few other usb chords from the back of the motherboard it power us after few hits, ( sometimes i have to unplug everything from the motherboard) this started happening a while ago, i also replaced the power supply about a year ago it is a 550W power supply? what do you guys think? what could the problem be? Thanks for any ideas or help

Welcome back!

Another NEW PSU is probably on the horizon. This time a Good One. Also, an UPS or good quality surge protector would be a good idea.

What CPU and GPU and how many HDDS? Also, do you OC the CPU or GPU? **

Also, what PSU are you running now?

** Recommended PSU Corsair - http://www.corsair.com/psufinder/default.aspx

The box says sustain velocty Extreme Cool Silent Design, im pretty sure its a dynapowerusa its a 500W im running 7600GS with two HDD 250GB and 500GB a new CD drive all of them are powered by sata, i also ran out of original plugs so i had to buy a regular 4 pin to sata connector and i also have a GPU fan card which takes up one 4pin connector, nothing is overclocked.

i also tried to unplug the GPU fan card and one of the harddrives and still nothing happend than i did the regular routine and it powered up

OK

 

[meddler66]

so you think its the PSU? not motherboard

 

[jaquith]

Based upon whatever "regular routine and it powered up" means it would seem to be the PSU. When a PSU is in its' early stages of a 'slow death' then sometimes it will run, run oddly, suddenly shutdown, and in general the PC seems to 'make NO sense' all of which point to a failing PSU.

As I recall, you are building a "new" rig ---> so try the NEW PSU; if the problem is fixed then you know 100%.

^ +1

sounds like a psu to me too. Do what jaquith said x)

 

[meddler66]

K thanks for help and by regular routine i meant unplugging all of the cables from the motherboard

 

[jaquith]

^ Then you 'might' have a shorted e.g. USB cable. -- Have any animals in the house {Cats, Dogs, Birds, etc} -- they love to gnaw {bite} on the cables...

 

[meddler66]

No i dont have any animals, and even when i unplugged the unimportant stuff like extra hard drive and some fans the computer still wouldnt start

 

[jaquith]

Then the PSU...and we go back to..."new" rig ---> so try the NEW PSU

 

[meddler66]

Ok thats what i shall do, but yeah i need this computer running properly before i get a new rig since this is going to my dad and hes pitching in on the new one

 

[jaquith]

Yeah Buddy! If needed -> then go to e.g. Best Buy {or similar electronics store with a good return policy} and pick-up a Corsair ; "IF" the new PSU does NOT fix the problem you CAN return the PSU.

^ +1 definitely a good way to test something xDDD hey you gotta do what you gotta do :lol:

 

[meddler66]

Yeahhh good idea man didnt think about it, i was gonna buy a cheap one off of newegg and see if it works

 

[jaquith]
