it's an old graphics card, it doesn't need any additional power supply. I do not have another one for the test, but I think if there was something wrong with the card, it would not display anything? The psu is not new it second hand and its good because i check it with my main pc psu and the same
this is the same problem, i see usb in the boot menu but it does not boot even when i remove all the disks it does not show an error that there is no system. there is only one slot for a graphics card
mmm and you don't get anything past the post even if booting from a pendrive, you said (I'm assuming you tried to boot the windows installer or a linux live distro).
Have you tried to use a different video connector of the gpu (assuming it has 2) ?
By any chance did you replace the shorted USB hub? I know you said you disconnected it, but there's a little more to it than just USB's.
The PSU is 450w? I ask because the Chieftec 450w PSU seems to have plenty of power on the 3.3v/5v rails (not just the 12v rails), but the 350w PSU may not. Dell's can be picky about that. Power requirements aren't the same from PC to PC. GPU cards also borrow power from the aforementioned rails and not just the 12v rails.
It is possible the burnt PSU overloaded the MB. But then I don't think you'd be getting anything whatsoever onscreen. Also, I don't think video is the problem since onscreen messages still appear.
this power supply is the Chieftec GPS-450AA-101A 450 W, I do not know what test you are talking about, the old power supply does not work. the only test I can think of is a test from the boot menu where it failed to show anything wrong. you say to connect a usb hub? btw the power supply I checked is silentium pc vero l2
The PSU now installed doesn't have a test button in the back like a Dell PSU. Otherwise, you could go through the BIST (built in self test) procedure that narrows down components to see which one may be bad. With a Dell PSU, and external peripherals disconnected, if you push the test button with PC off, and you get the green light, then internal peripherals should be good. Otherwise, it's unplug one by one until green light appears with test button pushed.

Hello,
I assume you don't have any other videocard to test ?
The gpu power cable ( assuming is using one ), is it connected ? Is the new psu .... well... new ?

There's a few ideas I have.
By any chance did you replace the shorted USB hub? I know you said you disconnected it, but there's a little more to it than just USB's.

I'm not 100% certain this applies, but you wanted to know the test I was talking about. I know it won't work with a burnt PSU.
How to Run a Power Supply Unit Self Test On a Dell Desktop or All-in-One Computer Don't let the title fool you. It's a way to test inside components.
Dell BIST Test Video
This case certainly isn't an easy one with everything passing diagnostics you ran from the boot menu. But we know something is seriously wrong.
