computer was working last night and in the morning. before I went to work i shutted the computer down. i came home from work several hours later power computer on : no display no keyboard lighting up, hear computer hard drive running cd drive working. I open the case and checked fans for processor and exhaust fan was working then turns off after few seconds. could i possibly have a bad mother board?
try power on , only motherboard out of case...if still power on for a few second, that motherboard problem or psu problem
power motherboard without cpu, memory or anything plug.
after power on for a long time try to put cpu without memory , is there any beep if yes bad memory, if no motherboard problem
