I have a desktop that has been reliable for 3 years since I built it. What I do is take parts from unwanted pc and turn them into working ones. but this is a pc that I built for myself not much for gaming but for personal use. it may not have good specs but they are:
an Intel Core i5-4570
Asus Z87-C
2x 4GB G-Skill RipJawsX DDR3 1600
Gigabyte Nvidia Geforce GT 650 2GB
1x 256GB ADATA and 1x Sandisk 126GB SSDs
Zalman GVN Series 400Watt powersupply
the problem I am having as there are four indication LEDs when the motherboard does its self-check. the first light that lights up is the CPU LED then it shows the DRAM LED then the VGA LED then the desktop shuts off then repeats. The motherboard doesn't even try to show a boot LED at all and there is no BIOS beeps which could indicate there is not enough power getting to the motherboard. It's like it tries to boot but it stops at the VGA check. the standby LED is let up as green and the four wires the gray and purple wires show 5.00 volts and the green and blue wires show 5.10 volts so it's normal.
so I have done the following troubleshooting which are:
turned on the pc with nothing but the power supply, CPU and one stick of ram tried the different ram in all different slots
tried different CPUs
Tried different GPUs
I have changed the CMOS battery
tried to reset the Bios
turned on the desktop without the SSDs installed
I have reseated the CPU 3 times
I have looked for bent pins on the socket and they look good
I have cleaned the pads on the CPU
I have replaced the rear case fan
so I'm out of ideas but I have my suspension and have narrowed it down to 3 things which are:
the BIOS is corrupted
the power supply is faulty
or the motherboard is toast
but I have come to Tom'sHardware to get some idea what is as I don't want to say buy a power supply and ends up not being the problem. so I need some help any ideas will be some help.
