Faulty Board or PSU? Start up troubles.

Recommended Posts

Yesterday my computer was working fine, as it had been for the past 3 weeks. I was as happy as could be with my new computer, and then this has to happen.

 

Today I moved my computer from one house to another, as I always do every week. Nothing was banged or bumped. I set everything up, went to hit the button...heard the fans buzz and saw my mouse light up, and then it went dead. I pushed the power button again, now not even the fans turned on. So I unplugged it and plugged it back in. Turned it on fans and mouse on and off again.

 

I opened the case when the power cord was plugged in and noticed that there were 2 LEDs lit up. I don't know what to infer from that. I suppose that the power is getting to the mobo to run these LEDs, because when I yank the cord they go out. So, I'm confused. I was thinking that maybe I should clear the CMOS or something, but I don't know if I can do that with the PSU acting like this, and I'm afraid that if I keep screwing with it that the PSU will take something else with it into the grave.

 

Thanks in advance.

two red LED's or two yellow LED's?.

does the fan on the CPU run?

my Antec SP-500 failed a couple days ago, and there was another post about the same time with a SP-500 failing also.

I just checked it, it's LED1(Near bottom left of board) and LED6(near RAM). I think they are both red...

The CPU fan doesn't start up, only the one in back and probably the one in front.

 

How could I check to make sure that it is the PSU and not something else? I mean...I'm pretty sure that SOME power is getting through to power those lights, but that doesn't mean it isn't faulty.

I bought a PSU tester from CompUSA, It tested my power supply as good, but computer wouldn't start, no fans at all, only lower yellow led. Swaped PSU with spare, now works fine. Easiest way to test is swap. Maybe you can borrow a spare from some one. Have you tried the power and reset buttons on the motherboard?

I just made some interesting observations. I noticed that the Floppy Drive power port or whatever (that one under the CPU) was disconnected. I also noticed that the audio module is also unplugged. I never knew that that connected even exsisted underneath the CPU, but I suppose (from the building guide) that it might be important. What kind of damage do you guys think I might have caused from not having these in? The audio module was plugged in eairlier today, so that might be it too...I need to get some extra cables tomorrow to plug these in, but I doubt they will do much...

The floppy connector and the 4 pin drive connector near it supply additional power to the mb, with a power hungry video card like yours there are necessary. There should be enough connectors on your psu cables. Got to go to work tomorrow, shutting down for the night, Good Luck.

All 4 power connections must be plugged in for stability. This is a requirement, not an option (regardless of what video card you are running, or what memory etc) - definately, definately plug them in.

 

If you still have a problem - follow the full CMOS clear (linkage in sig) exactly. If you miss a step (if, for example, you don't have a PS/2 keyboard) then your results will be invalid and you'll have to start over...

Hello,

 

The problem looks like the PSU, use another one or test your one in another pc.

I just hooked up the 4-pin cable to the mobo, turned it on...still nothing. So now I'm going for a CMOS clear. If this doesn't work I'll just send the PSU back tomorrow. I have access to some electrician tools, anyone know if it is possible to test the PSU to see if it is dead? I really don't have any way of swapping PSUs at the moment, even though that would be easier...
