help guys!!
pc automatically starting when plugged in without pressing the power switch
plus no display on the screen, all the fans running, no POST,no bleeps..is this a mobo prob??
Re-assemble the PC from bare minimum upwards, beginning with the proccy+mobo alone, then one stick of ram added, then the keyboard, then the mouse etc, note down the number of beeps for each case. Make a simple table on a piece of paper and record the things. Of course, don't keep inserting/removing each of the components when the PSU is on !!
Also, initially try the 'replace the CMOS battery after keeping it out of slot for 5 mins' thing. The same thing can be tried for the front panel connectors-especially the power switch alone-the others(restart & hdd led) can be connected later.
Keep some Iso-Propyl Alcohol alongside, and keep cleaning the gold plated contacts of each of the parts of hardware and their respective seats on the mobo using a clean piece of cotton - some time it can be as simple as dust causing these things.
