I'm not sure where to post this issue since I don't know what the culrpit is, but I'll try to keep this brief. I'm a 35YO PC Tech and have never seen anything like this. Just built my first HTPC in July.


Here's some of the components:


- Asus P4P800-VM Micro-ATX Motherboard (Rev 1.05, BIOS 1007)

- Intel Pentium 4, 2.8 GHz, 800FSB

- Windows XP Pro (SP-1 with all the latest critical updates installed)

- 1024MB RAM: Two Crucial 512MB PC3200 (400MHz) 184-pin DIMMs (running in Dual-Channel mode)

- ATI Radeon 9700 Pro 3D Graphics Card (128MB, Retail) w/Catalyst 3.7

- ATI HDTV Component Adapter

- Creative Labs Sound Blaster Audigy 2 Sound Card (w/latest drivers)

- Maxtor 160GB hard drive (7200RPM, 8MB Cache, Ultra ATA/133)

- Enermax 350 Watt Dual-Fan Power Supply (EG365P-VE FCA)


Here's the problem:


When playing a 3D game such as UT2003, GTA: Vice City, Half-Life, NOLF2, or RtCW, my screen will go all-black and then I'll either hear repeating high-pitched static followed by a high-pitch squeal, or I'll hear a 1-second clip of the last sound I heard in the game (like guns firing) followed by the same high-pitched squeal.


This only happens intermittantly, can happen at any time, and only in 3D games, not 2D apps in Windows.


I checked the temps and the CPU and mobo are always under 110F.


I ran Memtest on the RAM and it passed all 10 run-throughs.


I've tried older versions of Catalyst including 3.2 through 3.6.


NAV2003 with latest defs says no viruses.


Any other things I can try???? I can't quite pinpoint the culprit and it's driving me nuts! :confused:

Perhaps is the fan on your Radeon gummed/jammed or otherwise only intermittently working?


My Win2K had a bout of BSODs caused by the fan on my VGA card failing.

I check that out. The Radeon 9700 Pro is only 2 months old and whenever I tested the PC with the cover off, the fan worked. But nevertheless, I'll check it out.
