My pc won't post

Huor · May 19, 2014

So i'm on a running system since 3 years. I'm not english so forgive me for that, trying my best.
I tried to remove all rams, graphic cards etc and my Mobo won't beep.
Problems began months ago with regular blue screens, i always thougt it would be the RAM but can it possibly be the mobo ? (i wasn't using that pc so much, so didn't care with the regular blue screens and didn't check further by the time).

Any unusual noises from the power supply?

Also, remove the hard disk, then use only the cpu, one stick of ram on the motherboard then check if you can reach the bios

Huor · May 19, 2014

ok i unplugged all hard drives, plugged one ram, unplugged video card and plugged monitor on intregrated video card.
Still no post

Huor · May 19, 2014

i just wanted to add that i read forums for like 2 hours before posting this.

Remove the video card and use the onboard vga output on the motherboard. So we can narrow down the possible defects.

Huor · May 19, 2014

did that already

plaintuts · May 19, 2014

if you're unable to reach the bios with only the motherboard, cpu and ram then, do a cmos reset first then try again.

after that and still nothing then, remove the ram stick to check if the motherboard will produce a beep code detecting the absence of a crucial component.
also, check the cpu heatsink fan if it will continue to spin or stop indefinitely.
and if you have a different ram stick, try that.

Huor · May 19, 2014

ok i tried all those.
cmos reset didn't change
tried 3 ram sticks, still didn't change
removed ram and still no change
cpu fan continuing normally.

plaintuts · May 19, 2014

no, removing the ram on all slot would produce a beep from the motherboard indicating a missing component to start. also the cpu heatsink fan would start and then stop then start again, indicating a power cycle.

did you try the ram stick one at a time?

if so, try with a different power supply if you have one.
but as far as diagnostics go, its looking bleak for the motherboard.

Huor · May 19, 2014

yeah i tried all that as you said, i just can't try with another power supply cause i don't have another one.
This one seems to work pretty good(i mean its fan), also the front fans i have are working too.

check this.

it narrows down the problem to a faulty motherboard.

Huor · May 19, 2014

Thank you a lot for your help.
I'll then change my mobo.
Just a question about that thought, will my amd II phenom x6 1090 t (chipset AM3 890) will fit in another AM3/Am3+ chipset as of 760G or 990FX.
I could not find any motherboard with 890 still available to sell.

plaintuts · May 19, 2014

An am3/am3+ mobo will be compatible

Huor · May 20, 2014

Thank you again. I took the Am3+ 790G

Huor · May 22, 2014

so i replaced the motherboard, it worked correctly for 15-20 mins, then i got a bluescreen, i tried to reboot and never posted anymore.
I guess it's due to heat but i don't know what can cause that.

The fan of CPU was extremely noisy

you need to re-install the windows OS...

the OS installed on the hard drive is configured for a different motherboard.

do a cmos reset, then re install the OS.

Huor · May 22, 2014

how can i install another windows if i can't post ?

plaintuts · May 22, 2014

CMOS reset...
