1154254	2010-11-18 16:08:00	Hi there, I recently bought a load of parts and started to built my first computer. Everything was going fine until about when I was placing in the graphics card at which point the mains were turned on (I'm feeling like an idiot for leaving it plugged in there but heard you had to for ESD protection). I completed the rest (doubled checked all connections were where they were supposed to be) and decided to turn it on. No luck when I turned on the mains, only the front panel LED turned on, no change. The same applies to when I pressed the power switch on the front panel, no fans, not even one led on the motherboard, just that one on the front panel. What do you guys think has happened, has everything been destroyed? I'm really getting pretty upset over this cause I had spent a lot of money. Thanks	aeonplux (16084)

Everything was going fine until about when I was placing in the graphics card at which point the mains were turned on (I'm feeling like an idiot for leaving it plugged in there but heard you had to for ESD protection).Nothing wrong here. Just don't swap out parts when the computer is actually running. But what you did up there; I have done on a regular basis with no ill effect Sounds like your connections from the motherboard to the power switch are wrongly connected. Easiest way to ascertain this... on your motherboard there are a series of pins that look like ::::.:: (or similar) that a whole bunch of things plug into (case speaker/harddrive indicator light/power switch/power indicator light). Pull all those connections out - then with the machine on, run a flat blade screw driver across the pins so that it makes a connection between any 2 pins (i.e. : or ..). If the machine powers up, then you have just found the correct pins to use. If not, then you will have to go back and check your power supply to the motherboard... are you 100% sure this is connected correctly? Were the parts new or second hand? If second-hand, were they all known to be in working order? If the CPU and fan were seperate, did you apply thermal grease between them? (although if this was the fault, the computer would have started, and then shut down) What sort of motherboard is it?	Myth (110)
1154256	2010-11-18 18:31:00	+ 1 for Myth .... I had the same initial problem with a power switch being on the wrong : terminals .... maybe you have it connected to the reset contacts .... check the manual if you have one or Google the MoBo to find out which are the correct contacts to use.

1154257	2010-11-18 18:40:00	Gigabyte GA-P55-USB3, it might be just that,wrong terminals, considering no fans at all started up. All parts ordered new. And no grease was applied as its an intel i5 760 CPU and apparently the stock heatsink's got some grease preapplied On another note, should I try directly connecting case fans to the PSU to see if it's defective?	aeonplux (16084)
1154258	2010-11-18 18:40:00	many things can prevent startup - power switch as suggested, RAM not seated properly, problems with optical or hdd's etc. First start with the bare minumum connected, no drives etc, check the RAM is configured correctly and the right type, check the connections to the case are correct as per the manula (possibly take your time and be sure on this one), if your case or MB has a speaker connected it should normally give a single beep just before starting or a series of beeps to indicate an error	dugimodo (138)
1154259	2010-11-18 19:17:00	if its completely dead, then the usual causes are either the Power Switch is on the wrong header, look on page 26 of the manual, But heres where to attach (www.imagef1.net.nz). If thats wired up correctly, and the Power plug is connected in the board, and still no life, then the PSU could be faulty, the mother board could be DOA ( Dead) OR it may be shorting on the case, or shorting on one of the risers you attach the board to. You did check the alignment of the risers to the MB holes, and have not got a spare one screwed in. Even if the RAM was not seated the fans would still run. One way to test that, remove the RAM completely, start it, see if the fans jump into life, if they do it should beep indicating no RAM. If its still dead, theres another problem someplace. May sound silly, but look at the back of the Power Supply, make sure its actually switched on ( dont laugh - it does happen)	wainuitech (129)
1154260	2010-11-18 19:24:00	also make sure the small second power supply to the motherbaord is connected and if your graphics card has a power connection check that too (although wouldn't cause the problem you describe for graphics power)	dugimodo (138)
1154261	2010-11-18 19:28:00	Ok, update. The fans are turning on!. But only for a second then everything shuts off again. Is it due to me not connecting up the ATX 12V 2X4. I wasnt sure whether to connect it as my CPU (i5 760) isn't classified as "extreme". Should I hook these up?	aeonplux (16084)
1154262	2010-11-18 19:35:00	Not having dealt with i5 - I can only guess and say yes. But I would wait for someone who has dealt with them The P4 required the secondary power connector from the PSU to be attached to the motherboard, hence why I am saying yes. Also, are you sure the power switch at the back is on??? Simple mistake, but often overlooked	Myth (110)
1154263	2010-11-18 19:38:00	Yes - you HAVE to have two power Plugs attached. The 24 pin main power and the ATX 12V 2X4 Power near the CPU. Depending on the Power Supply, it may come with a 8 pin or 4 pin ATX. look carefully, and you will see it can only go one way some of the holes have chamfered corners the others are square. Once again looking at the PSU, it will have a couple of plugs that look the same at first glance, but one will be the ATX, the others will be PCI-E	wainuitech (129)
