No Signal
Hey, so basically I have an issue where my monitor displays 'no signal' on start-up. I also recieved MOBO error beeps (constant every 10 seconds or so). I took my PC to a repair shop, and apparently they were having issues with the mobo, so I ended up replacing it and getting a new processor and ram in the process. I've used my mother's 22" screen on my new PC, and it works pretty flawlessly. Whenever I plug my old screen in, it still gives me the same 'no signal error'. The only way I can get it to work is to start up with my mother's screen then plug in my old screen (19")...it seems to reset something. Also, whenever I started games / video driver installation with the old screen, the same no signal appeared. Same with resorting to the 1440x900 resolution that I've had it at for 3 years - I got the no signal message. I tried the old screen on my mother's PC, and on start-up I get 'out of range'. I have to start-up with her screen and switch over. It seems to work, but the colour is odd and again if I change the resolution to 1440x900 I get 'no signal'. Anyone have any idea? Should I just replace this screen, or is it a fault with my power supply/graphics card?

You need a new monitor, but have you tried your monitor on your mother's computer?

Yep, as I said. It starts up with 'out of range' - I have to plug her screen in first, then my old screen to get any display. It doesn't start up with no signal and it doesn't seem to display 'no signal' other than when I try to change the resolution to 1440x900. Sadly I don't have any games on her computer to test. It's really quite confusing...I'm pretty sure my pc is fine (works with my mother's screen)...

Definately sounds like your old screen is on its last legs. With the prices of monitors now I would replace it, it may well cost you the same, or possibly more, to repair the existing one anyway.

The simple test, which you have already done, is to try the monitor on another machine and try a known working monitor on your machine. Both those tests indicate that your monitor is faulty.

Just to check, when you try your mums monitor on your PC do you use her cable or yours? If you use her monitor with your cable then its almost definately your monitor at fault.

My cables, I've been sure to check that. The cables all seem fine. I've had this monitor for nearly 4 years and it has served me well, so I guess it's time for a new one anyways - I purchased a HKC LED 24" monitor and it seems to work very nicely.

Thanks everyone for the advice, much appreciated!
