Hi

I have just purchased an MSI Neo-F Mobo and have installed the memory, graphics card, cpu and put all the right connectors in the right place.

When it came to adding the front panel connectors, I put them in the right order and when I press the 'Power On' switch, the cpu fan moves a little and nothing else happens.

Does anybody know why this is?

Thanks
 
we need more description!!!

what do you mean nothing happens, do you mean the harddrives spin etc and the fan stops or the whole system switches off, any beeps, etc etc etc.
 
ok here the story so far.

Setup

Dual Core 930 3GHz
MSI 965 Neo-F
256MB Nvidia 7600GS
1Gig Samsung Ram
160GB Seagate Barracuda
New 550W PSU
Silver Dial ATX Case

The previous system I had, the psu blew up so I thoght I would get a new mobo aswell as a new psu.

I set everything back up. New thermal compound on the cpu, put the ram, hard drive and graphics card in and powered it up.

To start with, when I switched it on the cp fan would nudge a little and then nothing would happen. I took the screws out of the board so it was laying flat and free and switched it back on. Low and behold the system fired up, went into the bios and let it sit there for 10 mins to check the temp of the cpu and it sat there idle @ 26c.

I powered down the pc and connected the optical drives and powered it back up again. This time all it does is power up then stop for a second and then power up continuesly with no power to the graphics card. I have checked the graphics card on another system and its fine. I took the leads back off the optical drive and it still does the same. i get no power to the monitor, the hard drive seem's to be spinning, the only other things spinning are the fans. I felt the cpu heatsink whilst its powered up and it doesnt feel anymore than 25-30c so the cpu isnt overheating.

Any help would be appreaciated.

When you say a 550w PSU, what make is it? To abuse the old line not all PSUs are created equal although if it was an obvious inability to supply enough power for everything I'd expect the removal of the leads to the optical drives to allow it to boot again. :)
 
the monitor will only get a signal if the graphics card is running, that isnt the monitor's fault.

is the fan on the gpu spinning? have you tried re-setting cmos? is the cpu cooler power cable connected to the board properly?
 
The psu is an EZCool 550W and the bloke in the shop said it would run the mobo.

I have tried ressetting the cmos, took off the optical drive and it still does the same.

The gpu is passive cooled so there is no fan. The 20pin is in correct, as is the cpu power and fan connector. :confused:
 
have you plugged in the 4pin or 8pin adapter to the board and if there is a molex connector 1 of those?

ez cool are cheap and nasty!!! its almost certainly the psu at fault. the 550w ez-cool psu on another site is £18. normal psu's are £50+.

you get what you pay for!!!! surely you must have wondered why its so cheap??

go buy an enermax 600w sli psu or something.
 
connected the 4pin aswell but still nothing. What do you mean by the molex connector?

surely though, just to kick start a pc at stock speed this psu is enough.
 
take the psu back and get a refund. if you dont know what a molex connector is you shouldnt be build a pc!
 
I know what a molex connector is, I was just puzzled cos you said about the 4-8pin and then a molex connector.

Well I just tried a 400W psu from another machine and the same thing happens so it cant be the power.

Molex plugs are the plugs you use for optical drives and hard drives (if they don't require SATA power plugs), they have 4 pins.

Is the PSU supposed to be ATX 2.0 compliant? It should say on the box or the PSU itself. The PSU should be enough but as a comparison some supposed 550w PSUs will only provide around 350w continuously since the manufacturers pick the maximum output rather than a more realistic figure. :)

It doesnt say anything abot it being ATX Compliant. Just says ATX 550-JSP.

Could it be the mobo shutting everything down because the psu isnt good enough?
 
Just had a quick check at Ezcools website and it appears to have the required features to be ATX 2.0 compliant although I'd need to see the specification sheet to be entirely certain.

A poorly performing or damaged PSU can cause a system not to boot properly like you are finding but then if you have tried another PSU it shouldn't be the case. :)
 
You could ask the the guy who you got your PSU from to test it in your System. To at least rule the PSU out other than that you need to let some one check it out or you could make things worse.
 
i did have the cpu fitted on a different mobo when the power supply blew but if the cpu had blown, surely i wouldnt have been able to get the boot screen up a couple of times before this happened.

I did notice one thing, when I screwed the board to the back plate and then powered it up, the cpu fan would nudge a little bit then nothing happened but as soon as I took all the screws off the board/backplate, it booted into the bios and then thats when nothing happened afterwards.

another possibility is it could be shorting on the case some where. If you can get hold of another try another case

Thanks for your response guys.

I tried it in the previous case and the same happend. I even took the board out and tried on a test platform but still nothing.
