got a problem guys, my system switches off as soon as i power the computer on.
however, when i take the atx pci power connection for the CPU out, the computer remains powered on but obviously won't boot up. it's when i connect this power supply for the cpu that the computer switches off after i power it on...any ideas?

Is this a new system?
Are you overclocked, try a CMOS reset and single stick of ram.

yes new system but i have been using it for a couple days, its only today this started happening after i reseated the cpu

i have tried resetting the cmos and single stick of ram also, still no luck. also, when i hold the 'clear cmos' button on the mobo, the system will stay powered on but nothing will happen (apart from clicking of somesort i think) i took the battery out for a couple minutes bt still no luck

Double check the cpu again, why did you need to reseat the cpu.

cpu is fine have checked many times =(

was having problem with my memory. i have 6gb (2x3gb sticks) installed but the system was only using 4gb of ram. some guys on here suggested i reseat the cpu... ironic!
 
RJC said:
Hmm strange one, have you tried each stick individually just in case the memory stick you tried is the faulty one :( and try in each memory slot.

Another option is to test the board external to the case, the psu may be pick up a short on the cpu power connector.

how can i test it externally? u mean take the mobo out of the case and connect the psu like that?

Which connector do you call "atx pci power", and did you really take it out while the computer was running? If so I'm going to hazard a guess at you killing your motherboard by unplugging things while it was running.

I'm sure they meant reseat the heatsink, not the cpu. The common solutions for less than 6gb of ram being seen are increasing qpi voltage or decreasing pressure on the cpu socket, I think they had the latter in mind.

LoL Jon u really do take me as a **** right?? of course i didn't unplug or plug anything in with the computer running!!! sorry for the lack of detail! and no, they actually did advise to reseat both the block and the cpu. i tried decreasing the pressure on the cpu socket, but of course now i have this problem. seems as though i aint the only one however

right i hope i will be coherent now...

i am talking about the 8pin atx cable for the cpu. the computer keeps restarting itself after i put it on. it restarts itself immediately even before booting up. i was suspecting some link to the cpu as it started doing this after i reseated it.
so (after switching the computer off from the mains) i took out the 8pin atx cable and switched the computer back on, and with this the computer remains powered on (no restarting) but doesn't boot (obviously as there is no power going to the cpu)...
 
cheerz mate, yup as RJC suggested also, might try and test the PSU/MoBo externally. Will give this a go tomorrow or monday, but in all honestly I have a gut feeling the MoBo maybe knackered ='(
 
hey guys just a quick thing i was thinking of, on the mobo there is a 8pin pci power connection slot for the cpu socket. however, due to the shapes of the pins on the pci cable running from my psu, i was only able to connect 4pins out of 8. however, i then found an adapter in the psu box which lets me connect all 8pins to the 8pin slot on the mobo for the cpu socket. does anyone think there is a potential risk in doing this? overvoltage etc?
 
sorry i got bad habit lol, not the pci cables (these are in my graphics card) meant the molex type connections? will try uploading pics

p.s. have tried turning the cable around can only connect 4pins out of 8 running from the psu directly. but as i mentioned with the adapter i can connect all 8
 
my friend, it is the orientation of the pins in the cpu socket and the power cable for the cpu socket from the psu that dont allow me to connect the full 8pins. as u may know, u get 'square' type pins and 'rounded off' type pins.
 
will upload photos later tonight or tomorrow but there's no way i can connect the pins the way they are keyed differently on the mobo and the psu, thats for sure 110% photos will help prove my point i hope cheerz mate
