Suddenly.. no POST

Hi Dave,

the Asus has 3 years standard... Might worth a try to RMA it... Have you also tried the shorting of the pins on the PSU to see if it goes into full start mode?

You might be able to run the kit out of the case, i think how the power button works in that it creates the circit of the PSU (same as above) you could jumper the two or temp short them to see if it boots? With the Asus you wont need this as there normally is a power on button near the Pins for the case switches...

I have the same ASRock board in my media centre... I had no issues with mine, shame yours got damaged in transit, quite a good board...

Im looking at the Asus 560 TI's not sure to go 448 core or not as its more than 2 slots wide...

Hi Chris

I wouldn't know how to short the pins on the PSU mate.. I don't like shorting anything out!

Having contacted Overclockers re the original PSU and was told as it was over 12months old, I had to contact the manufacturer.. I'm certain the same would apply to the motherboard. Having had to send the PSU to Holland at no small cost, I can only dread where they'd ask me to send the mobo.. that is if I could get in touch with Asus. The Asus board can be started out of a case as it does have both pwr and reset buttons on the mobo for this purpose. As mentioned earlier, I've already tried removing and reseating the graphics card, ram and CPU and have cleared the RTC. Pwr On see's the fans start, blue pwr light on, onboard pwr/reset buttons lit, a brief flicker from the HD light, 2 green pwr led's on the graphics card but nothing else.. it remains in that state. I've not tried any of this with the mobo out of the case though.

I've just measured the 8800GTX and while it's the same width as the GTX560Ti, it's an inch longer. An inch doesn't sound a lot but boy, it makes one hell of a difference when you're trying to negotiate HD's and the like to fit or remove one!

Could be the case, sounds like it if the fault is identical... or a wire chaffed but I doubt that as you have swapped the lot. this may be of interest

£19.99 at the end of it you will end up with enough bits to build a new one!!
Re chassis and moboard if its shorting out is it possible to mount the lot outside the case so it cant short out anywhere?

[DaveB]

An interesting case Tony. Not sure I like the blue lamps on the front but there you go It's cheap enough mind you

The Asus board can be run 'out of case'.. no pwr buttons on the ASRock though.

I would try the Asus board out of the case using the mobo switch to test if there is a short. Try double/tripple checking every connection you can think of... If you can test each component on this, including 1 stick of RAM at a time... Might be worthy checking CPU and spare one aswell... A lot of work but hopefully yourll find out what is being screwy.

I think for Asus its europe somewhere, cant remeber from when i RMA'd my mobo...

I have the GTS version of the 8800 so these are shorter than the GTX so i may loose space in my case with the 560's...

Hi Chris..

Rgr that.. a little job for this afternoon

Just measured the GTX560Ti and its 9 6/10th inches (this is an odd ruler!!) from the back plate. In new money, that's 25cm The Asus card I have is such a work of art, I don't think I'll use it.. just keep it on the desk and admire it

There are faster versions and versions with more ram.. something to suit how much cash you have

Lol i understand inches! Ill loose 2cm (thats 0.787401575 inches) which may make things fun!

Good luck in the fault finding!

[DaveB]

Well.. bless my collar and tie..



What you see there is the cutting edge of good workshop practice The TFT to the right with the classic windows screen is the Asus P5Q working!!! I connected the GTX, 1 HD, a keyboard and mouse (left the E6600 and 2 gig Crucial Ballistix onboard) and nada Removed the HD.. nada Removed the ram.. nada Put the HD back and one stick of ram.. et voila

What does this prove.. well, I'm not sure It proves the HD and GTX work (though I never had much doubt). It also proves the E6600 still works but I'm not surprised as it did when it was taken off the old Gigabyte board (which was newish when it failed). It proves that ONE stick of ram works fine. It proves one stick of ram may well be effed. I can't understand why a faulty stick of ram would prevent a system from starting though. I've had em go duff before (though not for yonks) and they just died.. ceased to work. The only time I realised was when things were going slow and the system reported I only had half as much ram as expected
Is there a short on the case?? Well.. I don't know the answer to that. I'll try the system again with the other dimm plugged in and if it all goes pear shaped.. it will hint very strongly that that particular dimm is kerfuffed.

Plan B. I don't have one but at least I feel better now than I did 20mins ago

One thing you've not tried

Maybe the brand of tobacco in you pipe is not compatible with the current system?

[DaveB]

It should be ok mate.. it's Benson and Heroin Mellow Virginia.. backward compatible with all brands

Plan B. I put the other stick of ram back in and nada.. no post. Took it out again and rumpy bumpy.. the system flashes up straight away! I'd not have believed it had I not seen it with my own peepers

Now.. ref the Asrock board. That was all new to me.. different board, cpu and ram. 2 'like' components.. the GTX and the case. Where to now I wonder
