My pc's config is Amd 3000+, 1 gb ram,Asus a8n-e, 160 gb hdd,xfx 6600gt graphics, 2 optical drives and i use a lg 17" monitor and creative inspire 2.1 speakers. I run my system 24 * 7 . But i switch my monitor off to conserve energy. Whenever i switch off my monitor and then turn it on , my pc switches off. This happens only when i run my pc on a ups(microtek 800va 2 battery ups). When i connect directly without my ups, this doesn't happen. Plz help me. My monitor setting is 1024*768, 32 bit, 70 hertz. PLz tell me why this is happenning. Is this an ups problem?
