I have just re-seated both the peak card and the graphic card with no success.
I have cleaned all the contacts, either on the boards and the slots with contact cleaner.
The problem persists.
I have not changed any capacitor.
You think would be good to try a different processor?
Also i notice that the back plate, has a couple red leds on and they are on by this sequence.
1-on
2-on
3-off
4-on

Should i do/check something else?
Thank you for your patiente, i realy do need some help here.
Its the only machine i have.
