Hey there i have a custom built computer that pretty much worked fine until a few hours ago.. i was having a problem with my audio jack not reading my audio cable input sometimes. I opened up my computer case and attempted to repair this small problem, I made sure the plugs where my audio jacks were securely connected to my motherboard. I restarted my computer which booted fine, and then viola, right as i am about to log into my vista username it shuts off unexpectedly! I try to power it on again via the front power switch and nothing.. I turn the switch off to the psu in the back of my computer and opened it up and LOOKED inside again. I turned the psu on and there is a blue LED on the motherboard that is ON. So i don't think that theres anything wrong with my psu. I looked around for LOOSE screws that might cause a shortage. but without taking anything out of my computer i couldn't find (or hear) anything. I really have no idea on where to go from here..

Thank you in advance for anyone that MAY be able to help..

okay i called up evga for their tech support (which is really good) ive unhooked everything off of my motherboard except for my processor and my powersupply and it still doesnt start up. So i am pretty sure that the problem is my motherboard (unless the cable from the motherboard to the powersupply itself is broken) which is unlikely.. I am regestering my product and RMAing it today.Possibilities are your power SUPPLY is broken or the motherboard is dead. I suggest that you bring your computer to the shop and have it check. It is better to let the professional do the fixing to prevent further damage to your equipment.
