Hi
Just joined the forum, I hope there are some really clever people out there eho can help me.
System Spec's
Mobo- GA965P-DQ6 (rev 2.0)
Cpu - Intel Duo Core( not sure of model) LGA775socket
Zalman CMPS7000A Cooler
P/S CIC 650watt
Graphics Card - AT Radeon HD4850
RAM - Corsair 1024Mb, 800Mhz DDR2 (x4)
H/drive - Maxstor 120Gb Sata
CD/DVD Drive - LG IDE
Case - I-cute A78BN
Standard USB Mose & keyboard.
Ok, here we go, the Mobo,cpu, cooler, h/drive, cd/dvd drive were given to me, thry had just been moved from a system that a friend has upgraded.
I put it all together, powered up, and it booed up first time. Great I thought. Played around in the BIOS, setting time/date etc, and thought all was OK. So I put Win 7 Ultimate disc and drive and waited to see what happened. Well halfway through the install it died, as if I had switched it off. Hit power button again, fans tried to start, LEDs on fans and case flashed, are there it sat.
Ah I thought bad PSU, so straight back to the store, and changed it.
Put new supply in and hit on switch, and nothing, same as before, just a slight spin of the fans on all the units, LED flashes and then nothing.
Have disconnected everthing but still no joy.
Reset BIOS, removed CMOS battery for around four hours, re started and.... same as before.
Can anyone tell me how can I start the mobo, atleast to get to the BIOS, does anyone know the minimum you need installed to start the BIOS.
There is so much conflicting information out there that I'm losing sight of the problem.
Will a mobo get to the BIOS without a cpu?
Does it mean the mobo is gone? the cpu gone? Ram gone?
If anyone could give me some ideas I would be eternal gratefull.
Cheers

Hi and welcome to the forum.
Just joined the forum, I hope there are some really clever people out there eho can help me.
Well sorry you have had a wasted jouney then but that doesn't apply to anyone here ;D
I am bnot sure what yopur power supply is like but can youn post a link to it? Then I can get a better idea of it's capabilities. How much experience have you had of building systems?
-
This is the link for the PSU
http://www.maplin.co.uk/Module.aspx?ModuleNo=256613
It seemed to power system up ok the first time.
Not had a great deal of experience building from scratch, mainly doing upgrades to existing stuff. Never had a PC do this before.

Thanks for the info. In my honest opinion the PSU sucks. It should be more than enough to run what you have built but I wouldn't be at al surprised if that is your problem. It only has two 12v lines rated at 18A. If you check your manual on page 21 it says to make sure that the 8pin 12v connector mustb be installed for the motherboard to work. Your PSU only has one four pin 12v connector. Maplin are not very good for computer products and I would recommend that you use a retailer that only deals in computer parts. You will usually find the prices are better too.

The manaul is a bit different from the one that came with the boards, thanks for the link.
I'll search out a decent PSU for the weekend. I'm working away from home at moment so only chance I get to do things are weekends.
Strange how it started the first time, and then failed with another unit. I heard that some things from Maplins are a bit dobtfull, but I thought it would be man enough for the job.
Any PSU that you recommend?
I'll let you know what happens
Thanks
Mick
-
Enermax, Corsair, Seasonic and Gigabyte are all good makes although there are plenty of others. Try to get one with a single 12v power rail for maximum flexibility and stability.
-
Just to add my experiences of suspect CIT PSU's. I built a rig for a friend and was using a CIT PSU that exhibited exactly the same symptoms. The PC would start, then hang or wouldn't start at all or would run quite happily for a couple of days and then fall over. The PSU was replaced on 2 occasions, only to exhibit exactly the same behaviour. My friend took some convincing that it was in fact the PSU that was dodgy and it was only when I replaced it with a spare I had knocking around that the problem was cured.
He then spent the extra money on a 650 Watt Corsiar PSU and has had no further problems.
-
NO BIOS without CPU.
Does the board post to BIOS without any hard drives or CD/DVD connected, try that if you have not already.
-
No doesnt get as far as the BIOS just a quick flick of the fans and a flash of the LED's, then nothing.
anyhow taking Dark Mantis's advice and get a 650w 12v 4+4 single rail one from Corsair.
I'll let you know how it goes.
Why do they hve to make everything so damm complicated???

Actually just had another thought Mick. When you built the machine up did you make sure that all the old motherboard stands were out and the new ones only in the correct places? Because you could get exactly the same problem with a short.
-
Hi
Yes I fitted new stands that came with the case, it only needed 3 as the other 6 were part of the case. I was thinking about putting some very thin insulating washers under the board, just stick them over the case mounts with a touch of adhesive to keep them in place. Always feel a bit uneasy about fitting the mobo directly on to the case.
I don't think a couple of mill will make any difference to lining up the board with the case.
Mick
-
No as far as lining up goes it shouldn't make any appreciable difference, however some motherboards actually need to be grounded through those points to make a good earth connection.
-
Power unit didn't turn up, thanks Ebayer, Oh well will have to wait till next week end now.
-
Ah, the joys of buying of Ebay. ::)

650w Corsair PSU came today, plugged it all in and still won't work. Uplugged everything and still no luck. It tries to start for about 1 second, switches off for about 4 seconds then tries to restart again over and over again. Have check all hardware as far as I can, but no change. I have been through all the tests suggested by other memebers such as taking out memory sticks, but no luck. Theres no video output so I can't see if it is getting anywhere, no bleeps from theh mobo. I'm at a bit of a loss what to do next, perhaps its time to send this board to the nearest landfill site, before my strees levels go through the roof!!
-
One thing that wold be worth checking is the pins in the CPU socket. That is exactly the type of problem that has been showing up as a result of bent pins. They are not easy to spot and if you have any difficulty take a couple of close up macro shots and post them here for us to check for you.
-
Took out cpu and checked every pin in the socket and the contacts on the CPU with a very high powered magnifying glass and could fin nothing untowards.
Mick
-
Well that's good in the respect of there not being any damage but it still leaves you with a problem. :-\
-
case fans, psu fans, and grapgics fans all start together, but with the cpu cooler fan tries, it shuts the whole thing off and keeps going through the same cycle over and over
-
What is your CPU cooler and how have you got it connected?
-
Zalman CNPS7000A plugged in to mobo socket marked CPU fan. with a 4 way connecter, it won't reach anywhere else
-
I think I 've just about had enough. I've stripped out the cpu, cooler motherboard, and Grafics card and thrown them all in the bin. It would have been cheaper and less streefull to buy one to my spec, atleast I couls insert it somewhere if it didn't work.
Thanks for trying anyway
Mickn
-
Try with one stick of ram in slot one and one in slot two....See if it will post!
-
Did all that , have dissconnected all drives, only connections were cpu fan, 24pin connector, 8 pin connector, nothing happens if I take out the graphics card, so that has to stay in with its PCIe power connector.
Still no joy.
Mick
-
I'm glad that you came back mick and didn't just bin it all. ;) I think we have all felt that way at times.
I think that maybe you were on the right lines though and taking it all out of the case might be the best way to go. Make sure that you observe anti-static precautions.
Lay some cardboard or something similar that is non-conductive on the worktop and remove the motherboard/CPU/heatsink/fan/buzzer/one stck of memory and PSU from the case and put it on the cardboard. Now I know you haven't got any graphics but try and boot. The system should try and then fail emitting a series of beeps. Please post what sounds it makes.
-
+1 to that DM. Just to rule out a short somewhere.
-
Well fatman we did sort of cover this earlier but the OP was sure that he had built it properly so I sort of dismissed the idea, but I think it needs to be checked.
-
Hi
Problem fixed mobo screwed and now in the bin.
Talking into the tech guy who sorted it raised an interesting thought.
Well he says he has had loads of boards in with the same problems as I had, and they all have the same thing in common, ie all the power tracks to the cooler had urnt out!!
Yes I know we all have these wonderfull PSU's that can deliver massive amounts of power. but the problem is the mobo PCB tracks can't handle the current.
Everyone that he has done so far have had really high power fans in the coolers, and basically the PCB track can't handle the current load.
I suppose most people(me included) plug into the CPU fan socket, wrong, this is only OK if you are using a stock fan cooler. He advised that if you want to use a high power cooler take a feed straight from a spare from the PSU. Yes the fan runs at max all the time but so what!!
I'd rather it did that than over a period of time burn out the motherboard.
He maybe right or wrong, but is anyone else aware of the potential problems that can occur, not necessarly an immediate problem, but one that could occur over a period of time.
-
Yes quite right and something we didn't think about. :-[ How come it always seems so obvious afterwards. Mind you we always recommend running these big coolers and fans off the PSU directly.
-
Ah well its all sotered now, that for all your help trying to sort it, You must be up to superstar status by now

No I've been after Superhero so I can wear my pants on the outside of my trousers and take flying lessons but Gigabyte are holding out ;)
