fualty DFI or fualty CPU

Recommended Posts

Whent to turn on my PC today and it was completly dead.

 

First i suspected the PSU, but it had not problems powering up another motherbaord i have.

 

I unplugged everything from the motherbaord leaving the CPU in, still would not come to life (even tho there was an LED lit up on the baord)

 

So i removed the CPU and the motherbaord came to life so i thought the CPU was fualty.

 

But i noticed the lever that you use to clamp the CPU into it's socket, when you move it, the LED's on the motherbaord change brightness, sometimes they go off, other times they stay on. I have found that when i clamp the CPU into it's socket and the LED is still on i can power the motherbaord up with teh CPU installed.

 

So it really seems to me that the motherbaord has perhaps a dodgy connection somehow, or this could be the way they are i don't know.

 

Anybody had a simular problem?

did a regular cmos clear, i will try the one you linked. (i didn't figure a cmos clear would have anything to do with the motherbaord not even powering up?) anyhow my PSU is in the list.

 

I will report back with the findings.

 

 

Ok i followed the info in the CMOS clear link and no go. Ok i've also taken a friends powersupply which is the same as mine and it made no difference. I either have a fualty CPU or a fualty Motherbaord, unfortunatly i can't test my CPU or motherboard with his system as he is running intel.

The best you could do is to go to a computer store and ask if they could test your CPU there. (you could try with the mobo too but the cpu is easier to bring) You might want to try a smaller store, i find that those are more keen to try and satisfy your wishes as they see fewer clients.

 

Good Luck

OK i think its the motherboard. I have some strange happenings going on here, The light near the ram slots. The Dram LED?

 

Well when that is light up the motherbaord will power up, Now when i install a CPU that light goes off, but occasionally will stay on. Now i took the CPU out and try some ram, when ram is in the slot that dram LED goes out, as soon as i remove the memory that light comes back on, but i did manage to install the memory and the light stayed on, and the motherbaord powere up.

 

But everytime i've been able to power the mobo up, when you turn it off it won't start again. It will only power up flawlessly when nothing is plugged in except the power cables themselves, as soon as a CPU or memory stick is in the board trouble begins. I tried both sticks of my memory aswell.

 

How odd!!!

If you get your board back (assuming you've already sent it off for RMA) and it still doens't work - i'd really suggest that you try with a different PSU if you can get your hands on one, ie. different make/model. There have been quite a few problems reported with some of the Antec PSU's, specific to them not providing good clean voltage on startup...

hmm ok i will give your suggestion a shot ganders. I still have the baord.

 

Seems with a stick of memory installed (and nothing else) the baord powers up for a split second then shuts off.)

 

with the CPU in on it's own the board just will not have any activity. (altho the standby light is on the whole time)

 

The dram LED comes and goes. (goes off when memory is inserted or the CPU lever is locked down) also they LEDs change brightness. So cuould still be a PSU issue, just slim chances of 2 PSU's doing the same thing. my antec (and whole system) was running superb for past 6 months until today when iu turned it on and got no action at all.

 

Cheers.

ok so i have more info. The board powers up with nothing plugged in (except power of course).

 

It will power up with just a vid card inserted (x1900xt) and what i mean by power up is fans kick into action and all 4 red LEDS are lit)

 

It will not power up with a stick of memory inserted in any slot, also will not power up with a CPU inserted.

 

And once or twice it would fail to power up with nothing plugged in.

 

The Amber led is always on which says the motherboard isn't completly dead.

 

Should be RMA'd? i tried to file an RMA thru the dfi website a couple days ago still no reply tho.

Hello,

 

From what you said in your first post, Stop using the board and RMA it.

Is the ZIF socket level with the board, solder joints ok?

yeah soilder joints looked good, no dry joints i checked thouroughly. still waiting to get an rma.

 

just have to be sure it is indeed the mobo and not the PSU, as i noticed the psu is making a high pitch squel which i do not remember it having before. (also hope it didn't kill any other components)
