Here are the specs: Computer: Dell 4700 P4 3.4GHz 80GB HD DVD ROM 1GB DDR2 RAM @ 400 Mhz Audigy 2 ZS sound card eVGA 6600GT PCI express video card. 350W PSU (from a Dell 8400 - I replaced the PSU in the 8400 with an aftermarket PSU and switched the stock Dell 8400 PSU into the 4700.) First fried monitor: Dell M782 17" CRT Second fried monitor also a CRT. I have tried my Dell 1703 LCD and it works fine on either the analog or digital output. I haven't been brave enough to let the computer go into power saving mode though... (down to my last monitor now!) Here's the problem: Computer went into sleep mode/power saving mode and then the monitor would not come back on. It had power but would not show anything on the screen, just made a slow clicking sound. Tried another monitor. It worked at first. My daughter played a game for a little while and then stopped. When she went back a few hours later the computer had gone into power saving/sleep mode and the screen on the second monitor would not come up either, it has the same kind of clicking sound as the first one. Tried both of the monitors on different computers and neither will work now. Blank screen and clicking noise is all I get. While trying the Dell M782 CRT on a different computer it also made a loud pop - kinda like a firecracker. I unhooked and unplugged it once that happened. Any ideas???
