Computer power supply went out so installed a new one. 2 days later the monitor was froze so I shut the computer down. Rebooted and "No connection, Check signal cable" message on monitor. Tried another monitor, same results. Tried 3 new video cards and two new motherboards and a new power supply with no luck. Totally confused as to why none of these fixed the problem. Any ideas what else to try or what could be causing this problem????

Could you be a bit more specific about:
1) What caused the power supply to fail (your best guess if you don't know)
2) What specific order did you try these things in? And what combinations?
3) Have you checked your RAM? That's about all that's left in the equation (other than the CPU) that could be bad. Did you take precautions to prevent static discharge?
4) Do you get any beeps when the system starts up?

Thanks for the reply. Computer power supply just went dead. The computer would not turn on. First thing we did was replace the power supply and the computer worked for a couple of days. Then found the monitor froze with the Windows message and I could not get it to move so I turned the computer off. Computer came on but the "check signal cable" message appears but it also appears if the computer is not connected and I turn the monitor on. After we received this message we tried two different video carrs and then tried a new motherboard. When none of that worked we ordered another motherboard with on-board video and it still has no signal. When we got the new motherboard we had to buy new ram memory because the old memory would not work in the new mother board. In addition, the computer does not beep when you turn it on. Thanks.

Hello and tell me when you press the power button on your computer does the harddrive light flash like its suppost to when loading windows? Also do you get any weird noises from the computer??? last check to make sure the video card is put in stug and check all the wires connecting to the motherboard and make sure they are in tight (BUT NOT TO TIGHT) and try moving the memory thing to differnt slots. AT LEAST TRY! :thumbsup:
