Hey all! Been surfing this page for a long time but this is my first time posting. Glad to be here!

So let's get down to business, I've got a problem that is really wracking my brain here.
It started one morning when I woke up and smelled a faint burning smell (burning plastic). I didn't think much of it because it was so faint. I go to the office as I am about to leave and notice my wife's computer is not working, I also notice that this is where the burning smell is coming from.

Installed is:

MSI A75A - G35

AMD A8-3850 Llano 2.9GHz Socket FM1

Rosewill Stallion Series RD500-2SB 500W ATX12V
http://www.newegg.com/Product/Product.aspx?Item=N82E16817182076

Start to troubleshoot to see whats going on (unplug, plug back in, flip the switch, opened up the case (which was just cleaned out a little over a month ago)) and all I get is the fans spinning, all the LEDs come on, but no POST sound and nothing on the monitor. I come back that night and try to boot it up with just the CPU, RAM, and a flashdrive with the updated BIOS on it, same thing. So I figure since everything is coming on it must be the MOBO.

I order a new MOBO (GIGABYTE GA-A55M-DS2 FM1 AMD A55) and install that. Now the weirdest thing happens. When it powers up the LED in the PS blinks rapidly along with the power LED on the front of the case. What on earth could this be? Bad PS maybe, if that is the case why is it doing two radically different things with each MOBO? I'm stuck here and really don't want to buy a new PS along with a new MOBO if that isn't even going to fix the problem.

Thank you guys in advance for any help/advice yo can offer me!

Ya, I normally don't buy rosewill but my wife needed a Desktop and it was in a pretty decent combo, so I went for it. After inspecting a little closer the fans are powering up and EVERY single LED on the comp are all flashing with the internal PS LED. And the fan in the PS seems to be struggling to move then shuts off. Just weird how with the old MOBO it was consistent light and power, just no POST. How does that work?
