电脑检测卡（Computer test card） C0: boot detection code shows C0, which is the motherboard BIOS fault or motherboard chip has been bad C1:C1 to test whether the memory through, stop that is, but the motherboard is also suspected of failure C3: memory problems, D3, D4: This is the memory problem, but the motherboard memory slot is possible, most of the AMD board, then you can take the CPU fan out, tighten CPU, and then conduct power test 25: 25 for graphics or slot problems, generally cleared the motherboard, BIOS will be able to light the machine. Otherwise changed the video card 26 or 2B: bright machine, not bright, consider the video card 31: video card or slot problem 45: video card problem 00: just boot directly to 00 or FF is CPU or motherboard chip is bad FF: just boot directly to the 00 or FF, CPU or motherboard chip is bad, or may be insufficient power (20 floor, thank you) 13: the AMI BIOS13 is normal 75:BIOS fault, reset the BIOS can be 00: boot code goes to the last show as this is normal already light FF: boot code goes to the last show as this is normal already light 05 8042 of the control states can be obtained if manufacturing tests are repeated from 1 to 5. Soft reset / energization has been determined. The ROM is about to start. DMA as early as the preparation is in progress or fails. 06 make the initial preparation of the circuit chip, disable video, parity, DMA circuit chips, and clear the DMA circuit chip, all page registers and CMOS stop bytes. The ROM is started, the ROM BIOS check sum is checked, and the check for the keyboard buffer is cleared. DMA initial page register read / write test is in progress or out of order. Wuhan Ke Lan computer home repair phone 02707 processor test 2, verify the work of the CPU register. The ROM BIOS check is normal. The keyboard buffer is cleared and the BAT (basic guarantee test) command is issued to the keyboard. Wuhan Conan computer home repair phone 02708 make the CMOS timer initial preparatio
