Hello,

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.

Regards,
Syste...

Hello everyone...
Whenever I switch on my computer, monitor light is just blinking & no display.. I thought it might be because of RAM.. But when I changed my computer's RAM , same problem arises.. And whenever i remove VGA cable from the CPU my monitor just blinks & displays "Cable not connected."
Please someone tell me what to do now...
