Any advice would be much appreciated.A few months ago, I purchased an HP out-of-the-box computer with the following specs, and replaced the factory video card with a very expensive GeForce 6800GT 256mb video card.Specs:AMD Athlon XP 3200+ processor1GB PC 2700 SDRAM160GB 7200RPM Hard DriveGeForce 6800GT 256mb video cardNow, every time I leave the view on spot mode (with or without clouds present), the screen just blacks out and the sound just enters an endless stuttering loop. This also happens when I'm in Virtual Cockpit mode looking at a wingview. I'm beyond patient with this, and before I go and blame this on AMD, I'd like to at least try to figure out why this may be happening. Also, my computer stutters and sometimes hangs when I stream video online. Any ideas? Thanks!

You sure you have the latest drivers installed? Are you running Norton Anti-virus? I would personally format the HD and reload XP since who knows what kind of extra stuff HP installed.

I would try the latest drivers for your MOBO if there is any, video card, sound card, if you are using a SATA drive, make sure the SATA drivers are up to date.

Even downloaded the NVideo 77.72 drivers.No luck. What might be causing this, and only when in spot mode?

What are you detail settings, while your CPU is only an AthlonXP 3200+, it should still do well, one thing that can really kill FPS though in spot mode are clouds, report back with screenshots of your settings and we can maybe go from there to tweak them.

This is a long shot, but did HP use an add-on video card or is the old video card part of the motherboard? If it's part of the motherboard, you want to make sure it's disabled via jumper, bios, or whatever means provided for disabling it. In either instance, make sure the drivers are removed in case there's a conflict with your newer card. Last item--most off the shelf PC mfrs skimp on parts. Is your power supply up to the task of the new graphics card? That's one of the parts often left weak by off the shelf mfrs.-John
