I recently got my Athlon64 system put together, fully loaded, did everything myself (quite proud). nforce4 chipset w/PCI-express, 2gb of DDR-3200, Athlon64 3200, huge Antec case, and an NVIDIA 6600 with 256mb GDDR. Naturally, the nice keyboard and mouse (both Logitech, wired, and wireless, respectively)

Now, the first time I booted and installed FC3, it was great, but no h-w acceleration. I went to nvidia's site, got the newest driver, and went about installing them the EXACT way they said.

I didn't konw of a test I should try, so I just typed "glxgears" and the screen blinked to diagonally-tiled noise. The machine locked, NO response, moving the mouse didn't change diddly about the noisy tiled screen. Only thing I could do was reboot.

This only happens when an OpenGL-overlay program comes up, such as glxgears, tuxracer, xscreensaver with any of the gl-based screensavers, maya... The list goes on.

Has anyone seen this? Does anyone have a fix? If not, I'm just using my RMA and sending the stupid card back, because my ATI cards have *always* been under the "Just Works" tm. I'll give any info I need to fix this, it's very urgent.

Thanks in advance.

Also, forgot to mention: I'm running the 32-bit version of FC3 till I can get the dvd-iso of the x86_64 version, so the display drivers I have on there now are the IA32 release.

Would that cause the problem I'm getting? 32-bit OS on a 64-bit system, using 32-bit drivers instead of 64? Seems like it shouldn't make a difference, but I'm just wondering...

Okay, update:

I ordered an ABit motherboard (Fatal1ty AN8), and it has the same problem as above.

I ordered an ATI Radeon X700 Pro. First few dozen times I turned on the computer, it wouldn't get a display at all. I pulled half the RAM, and it powered on just fine. I went to lunch, came back, and the display was gone. Doesn't power on again. Nice...

I figured that changing out the main pieces would help, but... The same thing happens with any 64-bit motherboard. Video cards do not work properly. I was told that it's probably too small a power-supply (i have a 400w, i picked up a 600w at Fry's), but after testing it, it did the same thing. Could this be a RAM problem? Doesn't seem logical, but that's the only thing left, other than the CPU...

Has ANYONE had this problem? What is wrong with this stupid godforsaken thing?

Hi Jamie,

I have something the same and happily there are more!

I've got this system:
- VIA CUV4X motherboard
- PIII 800EB
- nVidia Geforce 2MX200
- tvtuner (hauppauge), networkcard, audio (soundblaster)

When I use GLX, my screen gets blurred and vertical stripes stripes appear. After a few seconds I get a hard lockup.

This is what I tried:
- I had a dual-boot with Windows, which could perfectly use my card, so it's not a hardware-issue.
- removing everything out of my pc except the videocard. Nothing.
- putting a big fan on my videocard.
- I switched to Debian-based Ubuntu today because I read there were alot of 3D-problems with FC3 (Fedora tends to be a distribution for the buisinessman who has Redhat at work, which doesn't play games). But no luck at all.

Sometimes I get some luck with glx for about 30 seconds and after that I get a lockup.

My next step would be upgrading to an AMD64 with a new videocard, but after reading your post I think I will switch to Apple
