I have an ASUS a7v333 motherboard with a amd 1800+ processor cooled by a ThermalTake 7 heatsink/fan. Its done it a few times before, but recently when i start up my computer in the morning (it seems to happen only in the morning, maybe because its colder) but when i turn my computer on, It says "No CPU detected, No CPU detected" verbally. Then after a few seconds, it beeps like the computer should when it turns on, and boots like nothings happened. Does anyone have any idea why it does this, or how i go about correcting it? My computer runs pretty hot, an average of 52-58 degrees idling. The airflow isnt great, so I was considering buying a new fan, hopefully thats more quiet, Zalman 6000-cu perhaps. Anyway, id appreciate if anyone could help me with this problem, thanks.
