I 've got the following problem, found a similar one in google but I'm confused and wanted to ask you some questions .
One of my customers brought me his computer, it starts, the fans are working but i see nothing on screen and i got no beep sound.
Here are the things I tried:
A) Changed the graphics card with another one, nothing happened, placed the card on my computer and it is working fine.
B)Tried to boot the pc with one ram at the time still nothing happened ( checked all slots)
C) Used the ram from my pc still nothing
D)Changed the psu installed it on my pc works fine, Installed my psu on that computer nothing happened again
E)Booted the pc only with cpu and an ethernet card still nothing happened (not even a beep)
F)Hold the power button for 1 min
G)Reset the motherboard battery
H) Installed the HDD on my pc and heard strange sound like a click ( i guess it's dead)
Something strange is that when i press the button to shutdown the pc, nothing happens i've got to remove the cable to shut it down.
I forgot to mention that we got a bad Electrical grid here with many black outs
I dont' know how to check the cpu,and thinking that the problem is the motherboard
What do you say?
Pc Specs are
PSU seasonic 400W
HDD Seagate Baracuda 500Gb
GPU PowerColor AX3650 512MD2 Radeon HD 3650 512MB
Motherboard ASUS M3A
RAM 2x Kingston KVR800D2N6/2G
CPU Is amd but i don't know the specific model just saw something like am2 socket on the mainboard.
Thanks for your time and sorry for the length of my post
