I got a case for my setup, it was great for a week, and a week later it stopped posting, bios speaker never beeped so i have no idea whats wrong. When i look at the ethernet port it is tryong to use internet or something involving the ethernet, i broke the wireless card and removed it, and have no ethernet plugged in. I plugged the original power led and switch in the system and the led was rapidly flashing. My only guess was either my biod got screwed or a component had died. If i dont figure this out ill get an upgrade but i dont habe the money,

By broke the wireless card i meant the receptors for the signals broke, i just removed the card from the slot
