Caporegime
Turned on my system for the first time in a few weeks. But no display on screen or no lights on mouse or keyboard. Lcd indicator on the board is dashing between codes 04 and 55. Tried clearing cmos via button on the back and removing the battery. Still no luck. Also, as the previous owner used this board for LN2 overclocking it had been covered in Vaseline for insulation. Noticed a few traces of it on the graphics cards pcie connection. Could this be a cause. Only other thing I can think off was that a few days ago the electricity in the house was switched off after a fault, the cooker set off the trip in the house and blew the main fuse.
