When I start up my computer, my monitor sometimes does not receive a signal from the computer and does not turn on. After a few times of powering off the computer and retrying, the signal will go through and the monitor turns on and works great. I don't want to leave my computer on all day long, but i also don't want to turn it off and go through this hassle every time I turn it on. Any ideas? Thank you in advance.

Windows XP

Monitor or video card(more than likely video card). Do you have spares to troubleshoot with?

I swapped the monitor and the same thing happened so I know it's not the monitor.

As I suspected. Then it's your vid card or mobo if it's online video.

This should be moved to the hardware section as it's not an XP problem.

I have swapped out the monitor and I still have the same issue. I am posting this in both the internal and external hardware sections because I am not sure if it is a video card issue or a monitor issue. Any ideas? Thank you in advance.

MOD EDIT; Merged from Internal Hardware One Topic is enough

IT can also be caused by failing capacitors on the motherboard. If you look at the attached picture you'll see how the good ones are flat on top and the bad ones are bulged and leaking. Sometimes they bulge on top without leaking too.

A good look at the motherboard for that problem. Mostly shows around the CPU and sometimes around the memory or between the PCI slots.

A good shop can fix that type of problem. I did a Dell SX280 this morning. 4 bad ones
