It’s a model # M5011 and when turning on the computer gives a normal boot tone and the hard drive is working but the screen is white with white lines. All capacitors on the motherboard were replaced and cleaned. It came with the ROM and all RAM slots filled.
Update: I have replaced both the Q1(2N3904) ic and U1(74LS38) ic no changes occurred.
