Hi all,

my system is no longer rebooting.
After pressing the power button, the power supply fan starts to run,
but neither the cpu fan nore the case fans start to rotate.
No Post on screen (device not found) and no beeps.
A power led on the graphic card indicates that there is voltage, also the fans of the graphic card start rotating. I can hear that the HDD is running as well.

Any idea or proposals?

Many thanks in advance!

Best regards,

J
