    Thanks Hydra, I will have a look but on ebay it is somewhere north of 130 USD plus shipping (and used). I do not know if they had already been bricked and survived by reballing or else. So that is a tough issue.
    And about the video mem, I am pretty sure it is because of that since when I start OCCT the card starts at around 120 fps but then suddenly it crashes as soon as the memory consumption kicks in. That was the only indicator of bad vram.

    There are GTX 560M Qosmio X775 replacement cards on Ebay. Unfortunately you can't change to a different card (other than the GTX 560M that is). The BIOS won't boot if you try. I have already. :(

    Thanks for the warning imglidinhere since I was seriously considering gtx 770m as an option. I will wait and see if the 90 ish prices+shipping come back since they run about 140 usd + shipping right now.

    From your old post?

    "The 570M is recognized by the BIOS, tested by one of the specialists whom I spoke with after he got off work. He says the 570M he used was a standard Clevo card from the Ebay user 'upgradeyourlaptop', I.E. Eurocom. He ran a few tests and found that the TIM used matters a lot in this case because your temperatures will be rather high. Any cooling mods like the ones listed here are advised if they'll work without much of an issue. I cannot post any pictures of this since I've only to take his word from it, however... it's definitely nice to know that there's someone who has attempted it and had some success."

    That sucks...

    Thanks for your kind assistance, friends. I have baked the GPU in the oven and it is now working showing video ram as 1536 MB as it used to be. I had the oven set to 200 C for 10 minutes and then put the GPU on an aluminium folio paper with the chip side up with 4 point alu-folio supports below the card for homogenous heating. I baked it for exactly 8 minutes and left it in the oven for about 30 minutes before taking out. It now works. I played Watchdogs for 40 minutes and NBA 2K for a while without a problem. I will do some serious stress testing tonight to see if the solution lasts and stable.

    All I know is, I tried to upgrade to a GTX 765M and the computer booted but only saw the card as a standard VGA adapter. When I tried to install the drivers, it said the computer didn't have an Nvidia GPU. Furthermore, when the iGPU was turned off, the computer simply had a black screen and I had to tear it down and re-seat the CPU to get the iGPU back on...

    So the 570M might work because it's still in teh GTX 500M line, but I know I couldn't get a more recent GPU to work. :( Which makes me sad...


    However I did just swap out the old i7-2760QM from my Alienware to this machine and the temps are about the same with the repaste and all that... so that's cool. =3

    I have a problem with my cooling. the cpu keeps hitting 80+ degrees while gaming which I just dont want to play with. I already did a repaste and the gpu temps dropped about 15 degrees but the cpu is still too hot.
    my fan is also not running hard at all no matter how bloody hot my laptop gets you can barrely hear it and theres hardly any air getting thrue the heatsink. im currently on bios 1.3, ive tried 1.1 and 1.6 and 2.1
    I remember the fan being able to blow quite hard when I bought this laptop so does anyone know of a solution?

    Look hard at the pictures in the first post. I think you missed a flip up connector...

    Look on fan sticker 12 or 5 volts? You can cut black and red wire, leave third tack wire alone, and substitute voltage. This is to see if fan now runs full speed and bypass motherboard speed controller. Or, easier way, plug in compatible fan for seed check. If fan was good before re-paste then triple check fan connector for stretched or broken wires. If none of the above works check on flat rate repair to see if worth it.
