I dont know how I can tell if its anything else? I tried booting with absolutely nothing connected except the cpu (minus any heatsink) and the psu leads plugged in. And thats with 2 different mobos with two different cpus. nothing happened on either so it has to be a psu problem hasnt it?

Hey Scottyboy, I feel for you. One other suggestion (but I am really clutching at straws now). Your "burning smell" post remindes me of a previous "experience".

Are your memory chips fully seated and their catches in place?

yep. I know for a fact its the psu now. I tried it in another pc and same problem. I wish i did that at the start, would have saved a lot of time

I dont get why would that happen though, its been fine for a year and now suddenly with new parts it fries? :confused:

scottyboy · 15 Jul 2007 at 22:51

btw..

never apply power to a CPU without the heatsink installed. A few seconds is all it takes to fry a processor. If you didn't kill it, consider yourself lucky.

Is that true? It wouldnt of killed the cpu if it didnt even turn on would it? im glad it didnt boot up after reading that.

Think of it positively Scotty, you are going to have to get a new PSU (= ££) but you have managed to narrow your problem to that specific component.

A decent PSU is always a good investment anyway and can last through several upgrades.

Like I said in a previous post, I am thinking of going for this

No that's not necessarily true at all even if you did turn it on for a while, especially not with newer chips, so don't worry too much

Intels have had thermal throttling for a while, in theory if not overclocked (and perhaps even when overclocked) they shouldnt fry......

See the youtube link for example video..... it's a little dated but it shows what i mean....

help!

I got the PSU today and have put everything together BUT..

when I turn it on, it comes on but then resets after a few seconds. I dont get a beep or anything, the fans all come on (EXCEPT the cpu heatsink fan :confused:

) and then they all go off and it seems to retry. IT keeps doing this..

EDIT its now not turning off ,but nothing is happing, I dont get any beeps..the cpu heatsink fan does come on it just keeps stopping/starting and then finally stays on. Im not getting any picture on my monitor either.

whats going on?!?

scottyboy · 18 Jul 2007 at 17:31

bit of an update...

I can get into bios!

It only resets/powers down/fans go weird/doesnt do anything when I run with both memory sticks in it. When I only put one stick in, it works, says its running in single channel and then goes into bios..

why doesnt it work with two modules in? Ive tested both modules and they are fine individually so whats the problem?

anyone?

Maybe it's a messed up DIMM slot, or do you need to put them in a certain slot order?

it says in the manual it has to be same colour for dual channel.

when I put them in the same colour, I get loads of short continous beeps (sometimes) before it shuts down and resets. Its not a meesed up dimm slot cause I have tried them all individually. It works ok if I put both in 2 diff colours but it aint running in dual..

Delvis · 18 Jul 2007 at 18:10

Surely thats the board thats faulty then...

Thats if you get 3 long-ish beeps in a row that is. That means faulty memory normally.

Lydzor · 18 Jul 2007 at 18:11

If that's long continous beeps its a DRAM error, short continous beeps is a power error. I'd imagine it's the first?

no, thats what I dont understand either. its loads of really short continous beeps not long.

so you think its the board thats the problem then? or could it be that the board just isnt set for dual channel and needs a firmware update or something.

would i have to send it back to overclockers (its over 7 days though but must be in warranty).

Lydzor · 18 Jul 2007 at 18:40

Can you try the memory on another computer?

scottyboy · 18 Jul 2007 at 19:15

but ive tried them both individually and they seem to work fine. I could try them on the other PC im using now, but its an older PC and wont support DDR2. will they still work on it?

Lydzor · 18 Jul 2007 at 20:44

Nope, you're DDR2 won't work in a DDR motherboard. As Delvis said, i reckon it's probably the board that's gone.

Delvis · 18 Jul 2007 at 20:46

Yeah, we've had it at work...

The memory works fine by itself, just not in dual channel =/ It's quite a rare fault really.

Just run a memtest on both sticks individually to be 100% the memory is fine

scottyboy · 18 Jul 2007 at 21:38

ok im formatting the drive now and am gonna run memtest. does that say for certain if the memory is fine? I think two of the dimm slots are bust cause when I try them both or individually in the two nearest the cpu, that fast beep comes on and it fails. but in the other 2 dimm slots it works.

also I checked the temp of the cpu in bios...is 21 degrees ok (system temp is 31)? I was told to check how many volts are going into the memory, but dont know how (it doesnt say in bios)

If I need to return this mobo, which i probably will, do i send it straight back to OC?

are you talking about this memtest?

http://hcidesign.com/memtest/

and run it in the background at 903mb for both sticks until it gets to 100%?

and wtf is this about?

windows could not start cause the following is missing or corrupt..

system32/drivers/pci.sys

that comes up after i try and install something of the gigabyte cd and restart. :mad:
