I took my computer apart today to clean the inside of it. After removing all the dust and putting all the hardware back in place I switched it on. There is nothing on the screen and then there is anContinuous beeping sound coming from inside the computer. I have looked around and checked the fans, unplugged then put back in the RAM and even reapplied more thermal Gel but still it continues to beep. I am lost and don?t know where else to look. Any advice??
