Computer wont turn on.

@ wazza the hole front panel was ****ed, first it was the USB slots then the rest went. I tried getting antec to send replacements but the customer service is horrific as they are american based.

Just ran the test and the PSU is working fine, the fan and lights came on. Next step?

you need to fully clear cmos,remove mb battery for 30mins if that doesnt work then leave it out overnight,youd be suprised howmany users have had success on other forums with this,try it you have nothing to lose

are any mb lights lighting up? and is cpu fan spinning ect?

What is CMOS? MB LED is on yes, no fans are spinning.

He's talking about resetting the BIOS by removing the battery on the motherboard for a while. Since the PC isn't even attempting to boot I don't see how that will help, but it won't hurt if you want to try it.

well mb lights are a sign the boards getting power,but cpu fan spinning lookslike cpu isnt,check your 4pin or 8pin power is fully plugged in,still could be cmos stopping it firing up

Ok I have taken the battery out of the motherboard, will leave it out over night and will get back to you tomorrow. Cheers guys.

just pinch the clips together by the battery and it should lift out,easy

right left the mobo out over night and still doesnt turn on, make a sound, no fan movement or anything but the LED light is still on. so frustrating. I don't think I've missed any pwoer supply into the motheboard. Got the 6 pin plugged in, the big power cable is plugged in, all the PCI express into the graphics card (2) hard drives have power.. I got a couple of the LED lights n that on the power switch cables not plugged in as im not sure which pins they go into, that shouldnt be a problem?

Edit: This may sound stupid but I was pushing the power button hysterically and then went away for 5 or so mins without turning the power off. I come back, turn the power switch off then I realised the processor fan was spinning. So it most of booted up way later after I pushed the power button.... Any ideas? Trying to get it back on again but no success.

Edit 2: Ok the system wasnt on but when I turn the power switch back to 0 then fans on the processor and graphics card have kind of a power surge and spin briefly.

PSU needs to be tested under load to properly eliminate it. I have had instances like yours. MB light is on and PSU appears to work. But fails under load. Not suggesting its your problem, just dont completely eliminate it yet. Good luck.

No reason exists to make that conclusion. Go back to what you know. Jumpering a green wire to black wire caused some power output. Normal is for a defective voltage to illuminate lights and spin fans. That jumper test can only identify failures. It cannot report something good. Appreciate that fundamental concept. Something that does not fail is not necessarily good.

Binary logic says what is not defective is good. The world is ternary. To know what is good means numbers. No way around the only layman’s tool that can report something good - a multimeter. Sells in M a p l i n for £7. A tool so simple as to be marketed to 14 year olds. Should be used by every secondary school science student.

Your best answer comes from a meter, one minute of labor, and leaving every wire connected. Then a next reply will say what is good and bad - without speculation.

Your choice. Either ask for directions how to solve the problem in a next reply (while borrowing a multimeter from a friend). Or start shotgunning; buy and replace everything because most any part could explain your symptoms. Without numbers, nobody can provide a solution. Actual number of suspects is large – without facts from that meter.
