I already replaced power supply also checked the old and new one, both are working OK, still unable to turn on the computer.
Try a hard reboot or reset . This is done by disconnecting the power cord so there is no power to thePC from any source. now hold down the power button for a full 60 seconds. This should discharge the cmos battery and clear the memory. Now plug in your computer and fire it up . Hope this helps .
