Bad psu ?

post #1 of 11
Thread Starter 
I was on my computer last night just surfing the net and it just suddenly turned off. I thought I had lost power but my pc had just stopped working. now when I try to turn it on absolutely nothing happens, no attempted startup or anything... the motherboard led doesn't even come on. which is why I think it is the psu but I don't know much about these things so any help would be appreciated. also for the past month or so my pc on startup would beep alot, I thought it was my temperature gauge beeping but I don't know now. I don't know if that effects anything or not but I thought I would mention it.

Yes it does sound like your PSU has died or there is a fault. Try testing your system with a different PSU if you can. Also please fill out your system specs in the user control panel.

How much did your psu cost you? Is it a custom built pc or one you bought from a shop?

The easiest way to see if there is any juice coming out of the pus is to run a wire from the green wire on the 20 or 24 pin mobo plug to one of the black wire beside it. If the psu doesn't fire up, thats your problem. I'll usually unplug everything else before doing that just to be safe.

wow guys thats probably the fastest reply I have ever gotten in any forum. I actually have been on this site for awhile but I haven't gotten around to filling that info out but I will do that when I get home today. anyway, I'm not worried if the power supply is done for because yes it is a custom built pc, and the power supply came with the case. what is oc'd on my pc is to small to mention (sorry to dissapoint haha but thats why I'm here). anyway, I allready made sure the power was good from the wall, and that all cables are connected. I don't have another one to change in, and I think I might take my pc to tigerdirect (its like 5 miles away from me) and have them test it and I'll go from there. I could be wrong but I think what happened is I upgraded everything too fast and forgot to buy a better psu to keep up with all the stuff I put in my pc and it just gave out, I mean it did come with the case.

Well i beleive i have isolated your Problem as the Generic PSU'S that come with cases such as yours are generally of a poor quaility and arnt built very well and therfore dont last very long mate so im thinking its definately Dead as you also said that you dont even get any LED'S to repsond on you Motherboard.
