Sometimes while sending IM's my computer beeps also but only under certain sn's... this beep is a real short beep the other is like a two tone alarm and lasts forever.
I am running windows XP home with an abit motherboard and AMD athlon 3200+ and isnt overclocked or anything has a gig of memory a 5200 fx video card and a 350w antec power supply.
the alarm to me makes it seem like an overheating issue so i tried to leave the case open and it rarely ever went off while using it.
The games my brother plays on it arent even games you install or anything. Its free games you can play online at like yahoo or somewhere like dxball and stuff. Sometimes it goes off while he watches clips of wrestling videos on wwe.com or something
My question is do u think a new HDD will fix the problem or could it be caused by something else like the CPU or mobo? if you need any more information just ask
