    Yep. The card gets its juice directly from the PSU. I have tried switching the cable around a couple of times, didn't seem to work.

    I believe this will fix it.

    Sorry for bringing this back from the dead. But after a few more weeks of trying and testing the problem still hasn't been solved.

    I have ruled out the PSU and the graphics card. The problem first manifested under load (graphical computer games) but quickly escalated and as it stands the computer does not boot (Machine turns on, whirrs but the monitor remains on standby and does not display anything).

    Would I be correct in assuming the problem now lies with the processor? Is there a way of identifying if a processor is burnt out, other than putting it in another machine?

    I don't think so, unless the thing has gotten fried to the extent that u can actually see the damage on the chip. But I think thats pretty rare. U have to get it into another PC to check it out.

    i had the same problem with my X700 it would restart automatically, if it freezes up first then restarts(without bein able to see POST) then its a heat issue (not enough of that heatsink white stuff underneath the fan assembly can do it..) but i found with mine.. that it was a hardware issue where the card was not performing properly and it started on fire after it blew some transistors or resistors. i would try another card or power supply or if you are a techy you could take apart the assembly and apply some heatsink if there isnt much there. Jims get a replacement card, its the video card, unless you have another card to put in the slot to check the slot on the motherboard.. ive had the same problems for a year and it was the vid card.

    Easy way to check if it is just the video is turn on your machine and your sound(hopefully you have a sound playing when you log into windows (im assuming your using that) and if you here it log in then its just not displaying your screen. if you usual hear a sound when you log in and dont then you've corrupted your bios and possibly your motherboard, meaning windows wont load because the instructions from motherboard and bios wont or cant send the info to the harddrive where to load from.

    Last night I wiped the CMOS and the machine began a normal boot sequence. Today I turned it on again and it did not engage the hard drives and the keyboard lights did not flash, so I wiped the BIOS again and rebooted, again it began a normal boot sequence.

    Is this a faulty motherboard?

    ALso the graphics card has been tested in another machine and does not appear to be faulty.

    Probably something screwing up the BIOS, thats for sure. But dunno what it is. Probably others will know...

    I think you should replace the motherboard.

    so you tested the card in another computer and it worked.. then obviously not the card as i suspected but that means motherboard issues you killed the factory bios.. under warranty? send it in

    Definately sounds like a mobo problem. Dying or faulty processors usually manifest themselves in BSoDs within the Windows environment or failure to install Windows (it should be noted that a processor will many times load Windos 98 just fine, but if faulty, will fail when trying to run Windows XP). I just fixed my long-time headache of a computer problem - guess what, it was the motherboard. In my case, it was just causing general instability, BSoD, and major headaches. Definately try swapping the motherboard, fail-safe defaults are another thing you can try within the BIOS, but if it doesn't run your parts to spec, get it replaced.
