When i run windows media player and sometimes when i play mp3's my computer sometimes either flashes up a blue screen and restarts or crashes with a wierd noise coming out of my speakers. when restarting windows tells me it has recovered from a serious error. the error reporting is not much help but it does five me the folling description of the problem.

Error signature

BCCode: a BCP1 : 00000000 BC2 : 0000002 BCP3: 0000001 BCP3 : 804F50B0 OSVer : 5_1_2600 SP :1_0 Product : 256_1


Does anyone have a clue what is going on. my computer also refuses to play C&C generals either restarting of crashing or exiting to windows with a serious error message.
Thanks for any help you can offer me.
