New PSU - black monitor

[christian0]

Hi guys

A few weeks ago it started smelling from my computer and a little later it said BANG and then my computer wouldn´t turn on again. Then I assumed that my PSU had burned out so I bought a new Corsair 750W PSU and put it inside the computer and connected the cables to the different components.

Now I can turn on the computer and I can see that the CPU cooler is running as well as the GFX cooler and a green light on the GFX lights up. But I don´t think I can hear any beep sounds from the motherboard but red, orange and green lights light up. But the monitor is black and showing the orange standby light.

What could be wrong? Maybe some other components burned out as well?

Might have blown the board too.

You didn't give any computer specs, so I'l give a generic answer. If you have another Video card ot Onboard / integrated graphics you can try, do so and see if you get anything. If you do and it gets to the first splash screen and starts loading, then the video card is blown.

Specs are:

12 GB DDR3 RAM
GeForce GTX295 1792 MB
1 GB HDD + 2 GB HDD
DVD-RW drive
Core i7 920 2.67 GHz

The old PSU was an Energon EPS-750W

Anyway most people say that probably either the GFX or motherboard is blown. But can the GFX be blown if the GFX cooler is running and the green light lights up as well and the orange light is not blinking either? Unfortunately I don´t have another video card to check that out.

If you could hear a beep before the incident at POST and can't now, The I would have to say that the Motherboard is probably toast. The 1st Gen i7 didn't have integrated graphics, and I don't believe I've seen a socket 1366 X58 motherboard with onboard graphics, so the only way to rule out the Video card is with another card.

There are still red, orange and green lights on the board that lights up near the RAM sockets but the motherboard can still be toast?

Take a close look at the motherboard and pay careful attention to the Capacitors. You are looking for any discoloration, or bulging caps.

Any electronic measuring device that can measure wether the board is blown?

Nothing really practical. Usually a visual inspection will turn up something. A I said in my above post, if you heard a beep at post before this happened, and now you don't, it is not getting through POST. With what you ahve posted, that could be one of two things: 1) the video Card and 2) the Video Card. That is whay I tell peokle when they do a build. if they need to cut costs, do not do it with the PSU. A cheap PSU will ultimately cost you more in the long haul. When one of those things go, they can take the motherboard as well as components. Not a happy thought. If it doesn't, you are lucky.
