Rampage or PSU gone bad

post #1 of 6
Thread Starter 
Hello everyone, i have a problem with either my PSU or my motherboard.
Problem started about 2 weeks ago. I switched my psu off(dont remember why) and when i turned it back on some hours later my pc wouldnt turn on. The lights on my motherboard, gpu and sound card were off as well. Nothing happened for about 5 mins then out of a sudden mobo lights turn on along with the rampage 2 logo. In about 10 mins the led on sound card turned on as well and about 15 mins after this the gpu lights came on as well and i eventually turned the pc with no further problems. Since then i turned my psu off about 3-4 times and all of the above happened each time. Today though i came home from work and all the lights of the pc were ok except from the gpu and the pc wouldnt turn on. I unplugged all the cables from the psu and plugged them in again and now not a single led is on,neither the pc is booting. The question is: what the hell has happened? Any suggestions on what to try and fix this?

I hope i didnt confuse you guys much since English is my second language.
Thank you in advance for all your replies.

I would suggest two things to try.

First I would turn everything off, remove the power cord from the PSU, and then reset your BIOS by clearing the CMOS. I'm not sure exactly how this is done on your board but I would suspect it should have a clear CMOS button somewhere. If there is no button then you may have to move the jumper pin across. It should tell you in your manual how this done for your board. The other way is just to remove your CMOS battery for a minute or two. Once that is done then plug back in and see what happens.

Secondly if that does not work you should ensure that your PSU is functioning correctly by jump starting it with a paper clip. Instructions on how to do this are here: http://www.overclock.net/faqs/96712-...upply-psu.html. Just make sure it is disconnected from your board and components. You should have a fan plugged into one of the molex connectors as well.

If You've reset your BIOS and your PSU is ok then it would be starting to look like your board is the culprit. Let us know how you get on.

Thank you Jokah but i decided to do the following instead.
A friend suggested that i use a power supply tester he had borrowed from his job. So i got the tester and plugged into it the 24pin,8pin and 4pin.
All the indications were ok but the 5VSB was indicating the following : LL
Anyone knows what that means?
Thank you

Sounds like the PSU is dead, or you have an unstable overclock

Try resetting the CMOS and see if that works, if not, sounds like the power supply's voltages are not stable under load
