wont boot with nVidia driver(8774)

[fooDK]

Hi guys.

I am pretty new at Linux, but I must say that I am very satisfied with the general function of the system. But one thing is bothering me.

I install FC5, and use yum for a complete update. Then I install the nVidia driver (version 8774) from livna.org, and it works great.

My plan for this machine is a Mediacenter, so after installing mythTV from ATrpms, and then a bit configuring, pretty much the whole system is working like a wont it.
Yesterday I then needed to edit a bit in the mySQL database for mythtv, so I startet op Apache

# /sbin/service httpd start

And got phpMyAdmin, copied it to /var/www/html/phpmyadmin/ and configured the stuff in the mySQL table.

But when I then this morning started up my machine, the screen blancs just when the nvidia logo is about to show before login. It looks kinda like it tries to show an image, but then after a little while it sets the monitor to standby.

Have any of you tried that the nVidia driver stops working over night?

My system is in my signatur below here, and I am currently using the 2187_FC5smp kernel.

Thanks

Regards

ok...
Tried making a clean install, and the problem was the same... It is the same driver that i have been using before, but it just wont boot x with it now...

If i (on kernel 2187) tries to boot with the "nvidia" as driver, it crashes, but with "nv" as driver it starts X nicely.
The nvidia logo wont whow either - so are my problem the driver og X?

Someone please help me, this is a big problem for me...
