Hi,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, Windows ME and FS2002.A strange problem occurs when I shift to the external views (S key): after a couple of seconds after I press S, most times the engine sound disappears if I use FS default aircraft, only if I give full thrust I can hear the spooling. There is no way to have it back unless I quit FS. BUT the big problem is that if I use 767 PIC (that is the only airplane I use), after pressing S the engine sound is replaced by a tremendous and very loud 'buzz' that needs an immediate speakers volume turn-down. Agian 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 decresased the audio compression, fiddled with the sound sliders and the Q key in FS, but no solution. My drivers are up to date.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.James

ME had the reputation of a memory leak disaster with higher ram capacitites. Your symptoms appear to be a video card driver problem and a sound card driver problem in dealing with memory mapping allocation in ME.The buzz could be do to that or a shared IRQ (look in Device Manager/Resources) that should not be shared.Congrats on your processor upgrade. You should really upgrade to higher level of Windows including the latest service packs and drivers for your cards from their respective manufacturers.

Ronzie,Nice catch with the 1GB and Win98/ME memory limitations. Hear are a couple of MS knowledge base articles:http://support.microsoft.com/default.aspx?scid=kb;[LN];Q108079http://support.microsoft.com/default.aspx?scid=kb;[LN];Q181862http://support.microsoft.com/default.aspx?...b;en-us;q253912A better solution would be for the poster to update to WinXP.W.

Thanks WS.Actually I've been quite stable with 98SE and getting 768 MB recognized (physical amount, don't have 1GGB installed) by using the VCACHE cheat described in other threads. With background stuff shut down, I go into FS with about 92% resources and about 500 MB free physical ram.

Short term fix - hit `q` then `q` again. That should get the sound back on external view - but you may now find it's missing in the cockpit (the double-q fix will restore it again)Medium term fix: Search the forum for KX Project. Replacement drivers which enable you to pull out all the unnecessary Creative rubbish and free up resources.Long term fix. Junk ME, buy a better soundcard. The Audigy 2 is SO much better than a Live! card! Hope this helpsAllcott
