Whoaru99 Posted January 28, 2013 Share Posted January 28, 2013 Last night I came home to burnt electronics smell that I found was coming from the power supply in my computer.Swapped the power supply for a known good one and the computer won't POST / won't show the BIOS screen and no beeps at all. The power LED comes on and the HDD light comes on and stays on.I removed all memory and disconnected everything, leaving just the mobo, processor, and power supply connected. Result is still the same. No POST, no BIOS screen, no beeps at all, just the power LED on and the HDD light on.From most I've read this typically indicates either mobo or processor is bad.Any thoughts on which is more likely?

Invader440 Posted January 29, 2013 Share Posted January 29, 2013 Did you make sure and plug in the separate 12v connector for the CPU? Quote Link to comment Share on other sites More sharing options...
upnorth Posted January 29, 2013 Share Posted January 29, 2013 Look at all the transistors/capacitors to see if any are damaged. I suspect that is the burnt smell you found. Quote Link to comment Share on other sites More sharing options...
Whoaru99 Posted January 29, 2013 Author Share Posted January 29, 2013 Yes, that was connected. Quote Link to comment Share on other sites More sharing options...
Whoaru99 Posted January 29, 2013 Author Share Posted January 29, 2013 Can't see anything burnt nor any bulged or blown capacitors on the mobo.The burnt smell is for sure out of the PS. Took the cover off and there is a burnt area on the circuit board and looks like one or two of the caps are leaking.Taking a chance...ordering a used mobo of the same make/model from that auction site. It's a little more than I think a mobo of that vintage is worth but the time savings for a direct replacement, not having to screw around with Windows reinstall tricks or funky driver manipulations to try to avoid reinstall, I think will be worth it.

thatoneguy Posted January 29, 2013 Share Posted January 29, 2013 when a PS fries it can well take the mobo out with it. hope it's a simple fix for y, and not a big headache. Quote Link to comment Share on other sites More sharing options...
Whoaru99 Posted January 29, 2013 Author Share Posted January 29, 2013 Thought about using this as a good reason to upgrade to a newer setup but this one had all the power and then some for what I used it for. So, yeah, I'm hoping $60 takes care of it rather than $360. Quote Link to comment Share on other sites More sharing options...
Whoaru99 Posted February 8, 2013 Author Share Posted February 8, 2013 Did end up being the mobo.First one I received from the seller had a few suspect looking pins in the CPU socket so I didn't even try that one. After sending a picture of the socket the seller promptly sent a replacement board, which is what's in use now. Quote Link to comment Share on other sites More sharing options...
