Greetings, My almost 3 year old Asus X52 F3SV Notebook suddenly froze and shut itself down today. It will not boot past the 'Asus' logo screen. The furthest it got was 'loading windows', but quickly rebooted once that screen showed up. It has been running quite hot lately, but i cleaned the fan out last weekend, and it had been running without problem since then. I'm running Windows Vista Premium, with no other real problems until now, with up to date windows updates and regular Spybot and anti-virus scans. There were random multicoloured lines running through the Asus screen on the first reboot after freezing. Could it be my graphics card? (Nvidia 8600m). I did not hear any crackling/popping sounds, so I really hope it's not dead yet. I've looked around these forums, but couldn't find a similar problem/solution. Thank you.
