Yesterday, I was thinking of upgrading my RAM. I bought 512 MB SD RAM, but when I opened my CPU I realized that I am not sure if my machine has SD RAM in it. So, I didn't put the new RAM. I then tried to switch on the machine to run some utility for checking my RAM type.

Unfortunately, when I switched on my machine, my display didn't come up. Now, I am having no clue what went wrong as everything looks fine but there is no display.

When I disconnected my monitor from the CPU, I get a test message as no signal. My monitor looks fine. Please help in sorting the issue out.

Thanks in advance.

System Configuration: Windows XP Professional
Internet Explorer 6.0

This usually happens when you are having an issue with your VGA chip. You might need to replace it. This is the last thing you should do, follow the steps given below first:
  • The VGA socket (where you connect the monitor cable for display) is loose. Open the CPU and press the card into the socket
  • Also, do check, at a time there are two VGA sockets -- one is the VGA output and the other is input. But, you must have plugged it in the input socket of the CPU. Change it.

Before that it, do one thing: Remove your RAM out of the socket (that's after switching off and unplugging the CPU). Now power up the CPU and start it. You will hear long beep sound. Keep it running for 5 seconds. Now switch it off and have the RAM back in the socket. Press it evenly on both sides till you hear the click sound.

Stats your CPU now!
