I upgraded mu cpu from Pentium IV 2 GHz to 3.2 GHz. Thus I had to change motherboard (now a P4P800-E) and RAM (now 1 Gb). I have a SB Live sound card, an ATI Radeon 9800 PRO 128 Mb video card and FS2002.
A strange problem occurs when I shift to the external views (S key): after a couple of seconds after I press S, the engine sound disappears if I use FS default aircraft, and there is no way to have it back. If I use 767 PIC, after pressing S the engine sound is replaced by a tremendous and very loud 'buzz' that needs an immediate speakers volume turn-down. No way to eliminate it, except by quitting FS.
Everything else seems to be working fine, I reracked and tested the sound card several times and no problems are found. I also reinstalled everything, but no solution.
Another problem I have is that when I toggle from FS to Windows, when I go back to FS the scenery is replaced by 'all black' and it takes quite some time of changing views to get it back.
Anyone could illuminate me on how to solve the problem?
Thanks a lot for any input.
