Just gave my mrs my old 19" crt so shes uninstalled old thing plugged new one in and now her pc wont turn on. Its got a light on the mobo so its getting power but nothing ekse She has plugged the old one back in and that didnt make a difference. Any ideas what it can be?

Hi, check and swap graphics card with know working one, or if it is on-board, then maybe plugging the monitor into the VGA port, damage was caused to the port and broke from the motherboard or blown card. Sounds like blown graphics card/chip.

Do you get the POST beep? Any drive activity?
Monitor might just be coincidental.
