I changed my PSU from Fortron blue storm 2 500w to CM GX 750w and now the pc won't boot. I checked all the cables! It was working good with the Fortron, so I thought that it will work again but it did the same when I changed them. All the lights on the MOBO light up, but it wont boot. Thanks in advance!

You may have somehow changed the video to internal or caused some board flex that damaged the motherboard or un-seated the video card or burned out something.

Swap with known good to test.

I removed the graphics card because I had to remove the MOBO battery to reset the CMOS. Is there any chance that the AC cable is involved, because I am using the Fortron's AC cable...

I'd move my video adapter to the internal and see if you get to bios.

Then you are back to diags. Look for any unseated cards or cards with edges that may have shorted. Look into pci slots to see if you damaged connectors.

One could have damaged anything mechanical or even esd wise with this. You have to either have some diag board or start swapping with known good to find answer.

if you dont see a post, all the lights light up, there are no beeps or led code flashes, then you have possible a video card issue.in bios make sure the video card is set to pcie, check all video cables, try a new one.
have you plugged in the power on the video cards correctly?
remove the video card,try booting with monitor on the board vgi if it has one. try a new card.
check all memory is correctly seated, use one memstick at a time.

i hate computers!
but cant help myself....

ok, i checked them all and got the PC running. So after it started i didi some backing up of HD's in case something happens and left it copying and went to eat. After about an hour I went back and the PC had shut down it self. Tried to start it up, but absolutely no response, no lights, no beeps. Afterwards I changed back to my old PSU and it all worked fine which leaves me to believe that there is something wrong with the GX 750!?

Old works, new doesn't simple enough one would think.
