I am building my first pc, the cpu, heatsink fan, ram and gpu are all installed i am now trying to do a external build to test it, the light on my motherboard is on but my fans for my gpu cpu and psu are not spinning, what do i do? :confused:
 
Hi and welcome,

firstly what parts have you got (Spec)?

Things to check:

24pin power cable is plugged in to the motherboard. (20+4)
4/8pin CPU cable is plugged in to the motherboard.
PCI-E power cables are plugged into the graphics card (6 and/or 8pin)

How are you trying to power it on? via the case power button? or does your motherboard have a buttons built onto it?
 
Have you made sure the power supply (PSU) is switched on?

Have you made sure you've connected all the power cables?

20/24 pin from the PSU to the motherboard (the main power cable).

4/8 pin from the PSU to the motherboard (the CPU power cable).

Any 6/8 pin connectors required by the graphics card.

How are you trying to start the system? Do you have a power switch connected to, or on, the motherboard?

What do you have the motherboard sitting on while you're doing this test?
 
Thanks for the quick responce guys the psu is on my 20+4 pin power connectors on and so is the 4 pin cpu cable, my motherboard has onboard graphics but iv tryed with the gpu and without and i get no display on my tv. my motherboard doesnt have an onboard power switch iv tryed shorting the pins and trying to attach the cable from the power button on the case to the motherboard all to no avail.

for refernce here are my specs:
mobo: Asus m4a88t-m
cpu: phenom ii x4 850
gpu: sapphire 6850
case: zalman z9 plus
ram: corasir vengence 2x2gb
psu: ocz stealth stream 2 600w
 
The processor is only supported by the latest BIOS, which is from February 2011, so hopefully you have that.

Have you tried resetting the BIOS by removing the battery?

Try with just one stick of RAM in each of the different slots.

You didn't say what you had the motherboard sitting on while doing your testing.
 
how would i go about reseting the bios? remove what battery? sorry if these are stupid questions, i forgot to mention that the mobo is on top of the motherboard box it came in.
i will try switching around the ram see if that helps

Disconnect the power supply from the mains and remove the battery.

As long as the motherboard is sitting on the cardboard box that's OK. You don't want it on the anti-static bag or anything else conductive.
 
this may or may not be relevent but the manual for my motherboard keeps telling my to use an IDE 40 pin connector but i dont really see how this works

The IDE connector is for older HDD's and DVD drives which have an IDE connection.

If your drives have SATA connections then you don't need to use the IDE connector at all.

SATA at the top, IDE at the bottom:
