That's my fault; these are the 2 DDR3 modules. This is the graphic card:

ASUS-EAH5450 SILENT/DI/ 512MB GDDR PCI EXPRESS

I know. I should have used that one and the shop should have mentioned
it to me, but I got a PCIe ienstead.

So better  not try then.

See above. I got the card that I didn't really need. I don't play games
on PC or anything.

My fault, I'm sorry. This shoul d be it:

Yeah, I replaced that already and then did a BIOS reset by replacing the
jumper (and then back).

These things I'm familiar with. Long ago I did a course 'computer
hardware'. Nothing fancy, just the basics, enough to build your own PC.
I can do that, although I did it only twice. It's just when things
(hardware) start breaking down I lack the knowledge.

I checked ealier: the PSU has an on/off button at the back. If I switch
it on the LED lights up, but only for a short time. After it switches
off nothing happens when I push the button of the tower.

Again, tnx for taking your time. This is the graphic card (that I didn't
really need :-) :
