    I just reseated the GPU and CPu one more time. Turns out I didn't lock the CPU in just now.

    Hey presto! My screen has turned on and everything seems to be working miraculously. I shall try restarting and sleeping to see if it lasts..

    edit: Also, I gave the VGA pin a good swab with some alcohol (Funnily, the only alcohol I had around was from a specimen jar containing cat fleas :| ew.) I suppose that either this or the CPU lock appears to have been the "fix".. It might not have been the CPU as i hadn't gone disassembling in that area before this all happened.

    Anyway, It's survived a shutdown and some sleeps. Here's to hoping it lasts.

    Congrats Duckydoug! :)

    Glad you got it going again!

    I would not be surprised if the PCI express pins, on the
    graphics adapter, and/or the slot, were the cause of the
    problem. It is not uncommon for dust/debris to work it's
    way in between the contacts. Over time, vibration and
    airflow allow the debris to crawl deeper into the contact,
    until eventually the connection is weak or broken. Cleaning
    everything with Isopropyl alcohol and a chemical brush (or
    paintbrush), and then lightly rubbing the graphics adapter
    contacts with a pencil eraser, will usually fix the issue, if
    it comes up again.

    Your recent booting problems were likely caused by the
    unlocked CPU. Your video problems probably were not
    caused by the CPU socket, unless the video expansion
    slot PCI Express lanes are connected directly to the processor.
    It's possible, depends on how Asus set it up. If the
    expansion slot is tied to the PCH, it is unlikely that the
    CPU reseating had any effect on the problem (if the CPU
    to PCH interface is faulty, windows would not have booted).

    Good luck,

    Sir Robin

    Logical explanations makes me a haaaappy panda. Thanks very much for your take on it :D

    I'll chime in in a week or two to see how my temps are doing when I get to apply the arctic silver 5 (evgasr2's recommendation) I just ordered. Idling at about CPU 55*C, GPU 60*C right now with the thermal paste all messed up.

    Still cooler than it was before I learned to disassemble and clean it thoroughly. GPU was idling at almost 70 :O
