Ok, newbies like myself are sometimes seduced by the 'free' part of dodgy s/w.
If I was running a moody version of XP Pro( hmm..) could that be the reason behind explorer.exe probs? And the fact that odd problems pop up - such as no sound in Win Media Player, even when I install V.9?? But Realplayer works....Stuff like that really.
Am running a Xp 2600 Barton o/c by 175mhz, 512 ram. Seems stable and therefore s/w not h/w probs. Memtest for 24 hrs was fine. Any thoughts....?
