Dobrov time of day, dear! Have the system unit HP dx7100 slim.Установлена mother p985H. Socket 775, P4 3,2 CM 915g.
the Problem is the following:start (off) by Pwr_on, spinning fans,squeak, no memory installed),heated CPU, warm, CM,YM hot but tolerable(in the duty room cold)Signal on vga not.
Power BP normal; CPU-1,3V; supply bridges-1,5V; power ddr memory-vdd2-1,3b;vdd7-2,6b;vddspp184-3,4V. When running moms from the duty room on the PCI A15 (rst) 3.3V(Ostrom signal reset failed sasec). The signal clk is present on the pci b16, Quartz all work out the desired frequency. When running in this mode until the measured voltage is hot MOSFETs of Metalnikov% of the finger does not tolerate, and inductance ibid.
Starting at the removed RAM,running fans, beeps 5 short signals, voltages are the same as with Ozure not heated procpr removed the radiator is heated,further trebuetsya because of preprava.
POST codes show can’t, no card, there is only Ozil and tester.
CMOS naturally dropped, USB called — a terrible experience.
Tell me what considerations? Experience in the repair of the mother is not great, do not know in which direction to move on.
