Hello i have a phenom 9650 on a asrock K10N78 Fullhd-hsli board 7 gig of ddr2 memory and 500 gig hdd with 8800 gts oc gfx card with a 750 watt psu when the 12 volt 4 pin connector is on the board it wont turn on or boot when the connector is taken off the board processor fan and board fires up any advice welcome please i think its the PSU but im not sure.martin

Hi Martin and welcome to the forum. :welcome:
I'm not the best person to help you, but I agree with your logic. Hopefully, Sandra, our resident guru will be along shortly.
-
Hi Martin, and :welcome:
As Rik says, Sandra would be the best person to help you with this, and she should be up along soon. :)

I would think its a faulty PSU, or at least the feed to the 4 pin connector isnt working properly. Have you got a meter so that you can check if there is any power to the 4 pin connector when the pc has fired up ?
If there isnt any power to it or less than the required 12v then maybe the board detects it and wont let the pc boot up.
I havent come across this before so its only a guess but I think its worth checking it.
-
Hi and thanks no i dont have a multi meter at all which i know is silly ill try buying a new psu see if that works im really annoyed at this as i have all my phohography work on that and now its playing up.
-
Have a look under the mobo too, Martin, just to make sure nothing is touching the case when that plug is connected.
-
from what i seee when i had the mobo out there is nothing wrong with it nothing chard on it no funny smells nothing one min it was working i swapped the hdd and then nothing it just wouldent work i have contacted tmsuppliesltd who have a shop on ebay i bought it from them in april says has a 12 month warrenty with it but they have not got back to me i just hope something can be done and i can get all my thousands of pictures back feel very sad......... :cry: :bawl:
-
Could you swap the drive to a USB cradle or another machine directly, and transfer the file that way?
-
AHHHAAAA i could try im just worried that ill be left with no pc to do my photography work on now and i cant afford to get a who new setup either not having much goodluck atm which is even more upsetting. ???
-
Well, salvage the images first, then tackle the machine. When did the problem start, when did you first report it to the vendor?
-
Started last night when i changed over the hdd's then it decided it would not boot and now i have the prob i have now where the 12 volt connector is in wont work and when out it has power but not enough to boot i reported it yesterday i understand that its bank hol so ill have to wait its just very very annoying and upsetting as it was a very hi spec pc and my gf is not happy with me as says i have wasted alot of cash..
-
Have you checked that you haven't dislodged, even slightly, any cables? SATA cables, for example, are notorious for being 'delicate'.
-
Yes have checked everything had the mobo out and connected all bits to it and still no joy i think the mobo might have a problem on it with the connector as the power does not get to where its ment to be might have to get new mobo might not even be the psu just feels alot of time has been wasted. :bawl:
-
In what way did you change over the HDDs?
-
turn off the pc changed the hdd over and turned it on and it said no os the mobo was out the case the next min it would not work i think its dead.. :cry:
-
Have you tried booting from a Linux CD? Assuming you changed the System drive, the machine wouldn't work. Where was the mobo at the time?
-
everything i try does not work without the 12 volt connector the hdd does not spin.
-
So, did you change the system drive and where was the mobo.
Until you can get this resolved, my best advice would be to try and recover the images to another machine, then try starting up the machine with only the graphics card installed. If that works, add one device at a time till it breaks. If it doesn't then it's most likely mobo or PSU, which is why the location of the mobo when you fired it up is critical.
-
ill try that later see what happens but since i dont have a 12 volt 4 pin not much works so im pretty stuck guess i best get saving and see if i can get a new pc and soem point,. :ack:
-
Try a new PSU, that will eliminate every else, or not.
-
Ill take mine to the pc shop tommorrow and see what they say if they say the psu ill buy one if not i think ill have to get a new pc lol..
-
I'd see what salvageable components there are first, Martin. A new mobo would be cheaper than a complete new machine. OTOH, if you want me to give you a reason to spend money, I can be very persuasive. :devil:
-
i think my phenom is ok i think my ram is alright as i got 7 gigs i have a 8800gts 640 meg ddr3 too with 500 gig hdd i need to know what mobo i can get as i have limited funds upto around 40 quid i dare to say..
-
Martin,
Write down here, each step that you have done, that way it is easier for people to try to help.
You replaced the HDU, then the PC did not perform a POST check or boot correct?
What did you do next?
-
machine was in bits in the case side i removed the hdd and replaced with other then i tried booting it and it fired up and nothing happened then i turned it off and on and then it dident do anything no sounds or beeps it would not do a thing i took everything off mobo and replaced them 1 by 1 and nothing still i took out the 4 pin 12 volt connector and the processor fan would spin but nothing else would work at all when connector put back in nothing happens just the light flickers on the fan thats it..
-
So is it possible something on the mobo shorted to earth, Martin?
-
Getting to sound like it aint it any ideas on the mobo front for a phenom 9650 for around 40 quid as i have cash in paypal account.
-
Well, I'd still start by eliminating the PSU and decide what to do from there.
-
well if it has earthed does that not mean that the mobo has died or would it blow the psu im not sure on some things i can fix and build pcs im just in alittle of a pickle on this one..
-
Do you have a reason to believe that the mobo may have shorted? OK, lowest cost approach would be to buy a meter and check the voltage from the PSU. If that's OK, a damaged mobo would seem to be more likely.
-
i dont know if the mobo has shorted might be the psucan always take my psu to the pc shop and ask them if its working or not and if not ill buy one i hope the mobo is not shorted as would save me alot of trouble..
-
That would be a plan. :thumbs:
-
would be a good plan ill see what they say if they say its ok then i know that i need a new mobo but im hoping for the best and see what happens ill have to keep my options open if i need a new mobo ill need one that will support my phenom. :thumbs: :-\
-
Get them to test the mobo if necessary.
-
ill see if they will for me as i dunno whats going on its just a real pain in the asss if u get me..
-
We do, Martin. I was working on a friend's machine this afternoon, and when I reconnected my own, it was a dead as a dodo. Think the PSU has gone. Computers are the devil's work!
-
its a very weird world i would think if the mobo was dead nothing would work and it would beep like crazy might be the psu ill try tomorrow ans see what they say i was in the study for 4 hours trying to fix it last night and it sent me mad..
-
i dont know if the mobo has shorted might be the psucan always take my psu to the pc shop and ask them if its working or not and if not ill buy one i hope the mobo is not shorted as would save me alot of trouble..
I seem to remember someone on the phone suggesting just that this morning, I wonder who that was :o:
-
;D
-
now let me think might it of been uncle glenn lol just seems very odddd..ill try tomorrow at the pc shop see what her says i can always take the motherboard down with me some how i think i have a big enough anti static bag and if there is a prob with motherboard hopefully tmsuppliesltd will comply with the warrenty side and help me out.. ???
-
If you have a 12v bulb from a car, say a sidelight or interior light rather than a headlight one, you could try that across the wires in the 4 pin connector to see if theres power there. Not sure what current they take so the lower wattage bulb the better but I would expect it to provide sufficient to light a 5 watt bulb quite brightly, may save you a trip to the pc shop.
-
Hello guys and girls i have taken the PSU down to the pc shop and guess what its working fine its the bloody mobo GRRRRRRR so now bought a new one off ebay still not heard anything from the tmsuppliesltd yet off ebay but hopefully they do cough up the mobo is still well within its warrenty.
-
Well, at least you didn't splash out on a PSU unnecessarily. :(
-
yes well thats true plus its a 750 watt one so im very happy that its not blown cost 45 quid lol the mobo only cost me 35 earlier off ebay just ashame that the mobo has died it has been playing up for weeks but dident think much of it.
-
They have a habit of sneaking up on you. :(
-
Dont they just b*****d things like i said for several weeks its been not booting properly and that i would sometimes have a blue screen it wouldent over heat it would just blue screen and stop working perahps it is just time for a new board :laugh: but then sometimes i wish it hadent of broke as was a very nice board the processor and the board together cost me 200 pounds.
-
Computers pick their moments, Christmas being a favourite. ;)
-
Lol yes thats true but its not the right time for it to of done it is it could of done it a couple of months down the line bloody thing hopefully tmsuppliesltd will give me a new board if not i have one on the way fingers crossed it will be here on saturday..then windows 7 here i come again lol..
-
well we will see what happens once i have my new setup people its the motherboard after all the hassle.new setup will be...
Asrock N68-S Socket AMD AM2+ Phenom Motherboard with 9650 phenom
4 gig ddr2
500 gig hdd
640 meg ddr3 8800 gts oc
if all goes well ill have a system back on thursday lol..thanks for all ur help :crazy:
-
I bought a new PSU for mine today, and after wiring and firing it up, well, it didn't. This time there was a light on the motherboard, so I knew there was power there, but it was otherwise as dead as a Norwegian Blue.
After swearing quite a lot, and dreaming up ways of fire-bombing PC World in the morning, because the 12v power connector only had six terminals instead of the eight that the last PSU had, I thought I might as well just try the other power connector, which only had four terminals, and bugger me, it worked, and I'm all up and running again.
-
Hopefully you wont need to reinstall the OS as its still an Asrock mobo but be prepared in case you need to.
-
hey yes hopefully i wont have to do so but if i do i do lol i have had word from the tmsuppliesuk people off ebay and they have asked me to send it back and a replacemnet will be sent out too lol well now i have 2 mobo's well either i keep them both or i sell one i dunno yet we will see what happens i hope the replacement gets here soon as i want to use all my ram i want to use the whole 7 not only 4 lol.. :thumbs:
-
You'll only get that with a 64-bit OS, Martin.
-
LOL rik im on the 64 bit OS i use vista and swear by it i really like vista i have the board i bought with 4 gig of ram on and it works ok im not dreading i got it TMSUPPLIESUK off ebay say they are going to test the board which i know is already bust so they can send a new one if they dont ill report them to ebay and see what they say they wont wanna ruin there 100% feedback coz of this surely.
