the board is a 1155 board , what model is your CPU

It's a intel core i3 processor 2130

ok , problem over , or no problem!


upon reading the manual again I realized that it was the older skt 1155 board , and that although skt 1150 and 1155 are physically interchangeable , they do not work in each other .


the processor is quite an old one ,


was it new? has it been tested?


the board needs bios 7751v16.zip , to make it work with that CPU , however we have no way of knowing if that has been installed.


back to square one ,


the led comes on , but nothing happens , it should spin even without memory or a graphics card ,


I am still going back to a power supply problem.

No it is the processor he's been using in the old motherboard, so it has been working fine.

Popped into PC World today to see if I could get a 4 pin to 8 pin adaptor (thinking it might need the connection to be spread across all 8 pins). The guy said there was no such thing, and that if the PSU only had 4 pins or 6 pins then the wattage/voltage wouldn't be right. So we'd need a new PSU that had an 8 pin plug.

enfield_freddy

and you believe the PC chuckle muppet?


the wattage on the PSU is the max it will give when needed , as you are using the same CPU , unless you were adding a very hungry vid card to the new system no change in wattage would be needed


voltage ? since when did they change the default voltages used in a PC


the guy is a muppet


do you have a local independent PC builder you can go to , take him your m/board , cpu and memory all built up and ask him to test it ,


if it works , enquire about the correctly plugged PSU




oh , in case I forgot , the guy at PC chuckle is a muppet and the reason that UK shops are closing down






PS , 4 pin to 8 pin adaptors do exist , http://www.ebay.co.uk/itm/like/310636535316?limghlpsr=true&hlpv=2&ops=true&viphx=1&hlpht=true&lpid=108&chn=ps&device=c&adtype=pla&crdt=0&ff3=1&ff11=ICEP3.0.0-L&ff12=67&ff13=80&ff14=108




in case I forgot , the guy at PC,,,,,,,,,,,,,,,,,,,,,,

I'm not sure I agree with the way it's phrased but I agree with Enfield Freddy, you're going to need a 4 pin to 8 pin adaptor to get that power supply to work with that board.

The 8 pin power socket does need all pins to be connected as it supplies power to the CPU (or at least all 4 12V pins but why quibble).

It's worth noting that if you have access to a multimeter you might be able to check the voltages to each component by looking at the power to the various pins in connector FV1 (see manual). This connector is optional so might not be present.

Make sure the OC Genie button is not depressed, you don't want anything over-clocked at this stage.

There is a power button on the board, next to the memory slots - the one with the power symbol on it, which you can use instead of worrying about the case power button for testing.

The easiest approach now is to find a local PC builder as suggested by Enfield Freddy, or even just your local PC nut who might have a spare adaptor or a spare power supply which you can borrow to test with. Unfortunately I'm 'down south' so can't help!

What actually happens when you press the power button ?

usually if theres a short, or some kind of problem, the power will flick on then off. You can usually notice this as the fans will move slightly.

If they do not move at all, its likely they are not even getting power, which could mean the power switch is not working correctly

enfield_freddy

or no power going to the board , due to the 8 pin connector not being connected , perhaps?

no that wouldn't stop the fans from powering up (especially if the fans are connected directly to the psu). the 4/8 pin give additional power, it gets it main power through the 20+4. You can run motherboards without having to connect those at all, althou it may effect stability.

i have an atom ion motherboard with a 4pin connector, and it runs fine using a pico psu connected just to the 20pin

And even if it was a problem, it would still attempt to power up, which will cause the fans to flick

I would advise against using an adaptor to convert the current 4 pin cable to an 8 pin one. Believe it or not, this is a fire hazard due to currents. You're asking a cable to provide twice the amount of power, which is likely to be more than what it was designed for.

You can go about this two ways. 1) Either buy a molex to 4 pin adaptor, this way you're not adding stress to the current 4 pin cable. You should be able to plug in the new 4 pin cable next to the existing one on the PSU. 2) I would recommend buying a new PSU.
