Have sympathy. Please help give a guy a break. No Display.

Hi, New to the forums and it always nice to meet new people so that the first thing I have had to smile about in a while so  .

A while back (read a over a year) my motherboard (an Asus L1N64) P2 power connector went. After a massive battle trying to RMA it, I finally got the motherboard the other week. I finally managed to find enough time tonight to try and set about reinstating it. Having backed up all my files I began to dismantle the computer I had cobbled together and used for the past year in order to use some of the parts ie case, PSU and hard drive.

To my dismay I manage to get the computer to power on but I have absolutely no display.

Now knowing that the graphics cards work, and that my power supply is fine is there any other reason I should get know display (not even bios) on start up other than the motherboard?

I mean is been a really, really **** year amongst other things with most of my spare time chasing various departments in Asus and creative computing and I can not express at how much trying to get this issue resolved is actually destroying me.

Any ideas will be hugely welcomed.

Thanks,


Sorry some extra info (I didn't read the Read Me).

The system consist of 2x 9600gt XFX graphics cards
2X's fx-74's AMD
Asus l1n64 MB
Misc. sata hd's
900W OCZ PSU
4 GB DDR2 Patriot

I think that is every thing that matters.

Obviously, LCD works (tested on my beat up Dell laptop rescued from a skip (I know this is irrelevant but I am so proud of it even if do over heat every 45min)).

I can not easily test the RAM but I would have thought the onboard RAM would still allow me to see the startup/ splash screen.

I know the cards work, can not be 100% sure on the RAM or CPU but I am fairly sure that they are okay.

I hope I have been a deliquent and missed something rather than have to go back to the *censored* that is ASUS RMA procedure.

Thanks

Ben

...my motherboard (an Asus L1N64) P2 power connector went...

Can you explain what you mean by this?

[No-one]

Hi thanks for the speedy reply,

For some reason the CPU2 connector (power )got scorched, and seemed to fry the board.. The board has subsequentally been replaced.

Please let me know if that claifies things. I am a little bit past my best to say the least...

Lots of hardware on this Bad Boy!!


Remove all components except the bare minimum required to get a screen display & enter the BIOS.
Monitor, keyboard, 1 RAM stick, 1cpu in CPU1, 1graphics card in slot closest to CPU1.

Hi, I have already done that. I hope I don't have to reinact:   http://www.xkcd.com/806/

But yeah I did the bare minimum diagnostic pretty much immediately, Again thanks for the speedy response.

Any other ideas?


Really, really needing  a win with this...

It is killing me....


Thanks,

If the CPU socket was damaged, I would think the CPU was damaged, too.

[No-one]

Hi it was not the CPU socket, It was the secondary power FOR the CPU on the motherbaord. i.e the 8 pin connector similar to that of the 4 pin you ussually get with 20/24 pin power inputs.

I hope this clarifies it.   This has since been replaced.

However none of my graphics cards seem to work now...

I am going to try them in another system on Monday with a bit of luck...

Otherwise I am going to call the lifetime warranty on them ..

Thanks for your help and if any ideas that would be great...

Before you said they worked, and now they don't.  If you have a cheap PCI graphics card lying around, try the Asus with that.
Asus has a pretty good track record with mobos, and since you now have a new one, the graphics cards are the only thing left.

Hi, none of my cards (incl. a cheap ATI card) are working on either board. despite 1 been taken of my working rig.


now none seem to work...

I am going to purchase a power supply tester just to double check all the power and then I can eliminate that. then I will try and see if I can get any of the graphics to work on a completley different machine....


Let you know more as I have it,

Thanks for your help thus far,

1.  none of my cards (incl. a cheap ATI card) are working on either board. despite 1 been taken of my working rig.

2.  I am going to purchase a power supply tester just to double check all the power and then I can eliminate that. then I will try and see if I can get any of the graphics to work on a completley different machine....
...

1.  Some are not auto-detected by BIOS; also default is mostly likely PCI-e, not PCI.  Install card, remove CMOS battery, reset CMOS via shorting pins (if so equipped).  Now power it up.
2.  Is this the same psu that "scorched" the 1st mobo?

[No-one]

Currently it is but wasn't at the begining of my diagnostics? I had a cheaper 500W I was using 'til I "confrimed" it was working without a pSU tester.  After shorting the pins, on pulling out it mad contact with another and I think it has blown something...

I have used however both PSU with the Graphics cards in question in virtually all configs...

Going to see if I have another computer to test thge graphics on.... if they dont work I will try and see if I can get a cheap one of ebay for a diagnostic test.


Will try the CMOS thing later as I have some work and it is already 21:45... and I am up early  Thank god for good esspresso is all I can say

Thanks and I will get back tou hopefully within acouple of day with any new info....
