I'm sorry, i know you're helping me here and that the answer is clear for you, but i have no idea what you just said.
What exactly is the problem? And what can i do to fix it?
Why is it that sometimes (rarely) it starts fine and sometimes it doesn't?
Sorry if i'm annoying you.

Edit: ok, i understood what you said and i tried it. The slot stood constantly at x1 speed what ever i pushed at the card... and it works like sh1t. From what i understood, x1 speed is even slower then AGPx1 which is ancient.

And i believe you didn't read all my post, you just jumped to that conclusion. The only moment the slot works at x16 speed si when the pc starts without failing at first. And when it starts like that, the slot is constantly at x16 no matter of power saving or w/e you can think of. I was thinking of maybe updating the mobo bios, but this problem appeared about a month ago, it worked fine until then. Is it maybe some faulty hardware? And if yes, why not always? And what could be the problem? Mobo or video card?
