Hi all

I recently got an atec p180. After changing all the parts in my old case to the new one, i fired my computer up however it would not post. I thought this could be because of the case. I tried running just my motherboard, graphic card, cpu and ram open case (on my desk) and it still didnt post. What could have happened?

Specs

Intel Pentium d 805
evga 650i
evga 8800gts 320mb
seagate barracuda 80gb sata
Hiper type m 530w psu
crucial ballistix 2gb ddr 5300
 
Well, anything could have happened mate.

Have you tried taking it apart & double checking you have everything connected correctly, that where I would start:)
 
Ive tried everything. Changed the psu. Tried running it with jus the motherboard and cpu, reconnected everything properly but nothing happens. the motherboard doesnt even beep.
 
You have a speaker on the motherboard then? How about if you power up with no RAM installed, you should get error beeps then indicating no ram is installed...obviously :)

If you DONT get beeps...then try reseating the cpu and trying again...

Just to double cheeck, you definetly have all power cables in? 4-pin power and 24 pin power?
 
You didnt have any stand offs in the wrong place when you built into the 180 did you ?

Like most have said are you certain everything is plugged in ?

PCIEX Cable in the graphics card ?
4pin / 8Pin Connected to board ?

Obviously the 20/24 pin is connected or the fans wouldnt spin :P

When the fans are spinning try resetting your bios my shorting the pins, might fire up 2nd time around.

Id try what delvis said though and try get any kind of beep out of it be it no memory or no graphics card

Good luck
 
If no RAM is fitted & no Graphics card, no USB headers, no Drives etc but the power switch is (& is working), we have it down to 3 items already, PSU, CPU or Mobo. The PSU is the easiest to check or swapout so I'd start with that. I wouldn't advise shorting the pins when it is powered up, you are creating a short circuit & it will damage some Mobos despite what some people say, other Mobos are tolerant of it I will agree.
 
I had something similar with a Gigagyte board. Turned out to be it would only work with the 20 pin power connector fitted. If I used 20+4 pin I had the same symptoms as you. I doubt that is your problem, but everything is worth trying when you're desperate.

I doubt it will in this case. It is a small amount of memory that holds the Mobos settings + keeps the time/date running when the PC is powered off. Sometimes it gets scrambled & needs to be wiped in order to enter some valid values to enable the board to work. There are usually 3 pins & a jumper to connect 2 of the pins at any one time. One position = battery in, no jumper = battery disconnected & the final position = the "chip" is shorted out to drain it. I advise under no circumstances to ever power up the board in this position as it will damage some boards. (Some it won't)
 
If you're using dual channel memory, make sure you've plugged it in the right slots. I had the exact same problem with an old asus board, moving the memory around seemed to fix it.
