Hi I just finished putting all the wires in and parts, and went to plug it in but it wont turn on?

Please help me :)
 
Couple of things to try.

1. Did you install the standoffs between the motherboard and case?

2. All power connections are in? If you miss your 8 pin EPS, you will not boot. Same to the 24 pin ATX.

3. Did you turn the power switch to on, on the PSU? That will cause a no boot.

4. Reseat RAM.

5. Reset BIOS. There is a pin for that. Look in the motherboard manual for that.

6. reseat CPU.

7. Pull board and make sure you only installed standoffs where they are needed. If you have more than is needed installed, it will short and not boot.

8. Paperclip test the Power Supply. Google it, it is easy to do.

9. Give up and take it to a shop.

thank you :) I'll give these steps a try, I really want to get this thing working :)
 
I just though of another test too. Look at the wires for the front panel and make sure that they are attached right. I have done that wrong before. my reset button did not work for a week or more because I attached it backwards.

I am really unsure about these wires coming from the front panel, there's some things coming out of there saying Power led + and - and Power SW and I've put the one's with an arrow in the +

But it also says FP PWR/SLP twice and I have no lead for this?

Also, I cannot find the place to connect it on the motherboard, I had them in JCOM1

thanks :)
 
That is why it is not starting. JCOM1 is for a serial port. Those are ancient ports.

What motherboard do you have specifically?

Thats good news :) thank you :) it's this one :)

MSI Z77A-G43 - LGA1155 INTEL Z77 4*DDR3 GBE LAN 4* USB3.0 ATX MOTHERBOARD

http://www.ebay.co.uk/itm/280966342...X:IT&_trksid=p3984.m1439.l2649#ht_1285wt_1139

thanks :) I've spent ages looking through youtube for video tutorials on this motherboard but have had no luck, and I have one massive head ache just want to get this thing working before bed :)
 
They go in the JFP1 port using the pattern shown below.

Uhoh it's turning on, making a rev noise with the fan and turning back off? :o

and it keeps turning on/off automatically

MSI are officially arseholes. No Bebug LED. :(

Okay, Reseat RAM, and check that all power leads are attached.

thanks :) there is a 4 pin connector spare from my OCZ 600w PSU but I have got an 8 pin in the motherboard, I am wondering if it's that?

I'll try reseating the RAM, thanks :)
 
No. The 4 pin is for P4 adapters. It is just like the floppy plug that is on your MOLEX lead.

As long as your EPS lead is plugged in, you are fine.

thanks, I've tried the RAM but it's still not powering up, I have not used any Molex leads in the build at all as I couldn't see if they went anywhere, maybe this is why?
 
no. They go to IDE hard drives, Water pumps, Fans (when not attached to the motherboard) and several other add ons.

Reset the bios.
