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

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.
1. check the RAM is seated
2. Try any other RAM
3. still the same problem check the video or graphics card , if any
4. if no graphics card and problem stiil changing it clear your CMOS by removing battery
5. if its new system then, remove battery, then take a small wire piece and short the positive and negative of the battery socket, then only CMOS is cleared
6. still problem , check the processor heat sink
7. still problem then suggesting checking motherboard and processor
