So my problem is that my monitor [might be time for an upgrade, this is not the 1st time by any means I've had problems w it] does not display any picture. I turn on my computer and it cycles through D-Sub, DVI-A, and DVI-D prompts. It settles on D-Sub but then goes dim from a green light to an orange one and displays the Error "D-Sub connection error." This morning I got my new memory, and installed that. Everything was unplugged and off and I grounded myself before touching the computer. Then I saw that my 500 gig secondary was unplugged so I replugged it with a SATA2 cable. I did nothing else! Computer was working perfectly yesterday....

I checked my cables are tight and they are and all plugged in.
I pressed some buttons on the monitor to cycle through modes, D-Sub, DVI-A, and DVI-D. They all give the no connection error. I booted up and pressed F8 like a madman but no safe mode because the monitor doesn't work.... I'm on spring break now so I'm thinking maybe it's time for a new monitor and it will come probably right before classes start. I know the VP201b is old but it's a good workhorse and i'd like to keep it living if possible.

FYI I was looking at this new monitor. Highly rated, many eggs and decent price.

Would it be good for my system? I see it says DVI for imput so I think I can make that work, yes?

Please help
Thank you for reading my thread, I'm sorry for it's length

Test your monitor with the onboard video before you buy a replacement monitor. I would even borrow one to be sure.

Double-check your cable connections, and try the secondary output on the 560 Ti if possible, before testing onboard video.

Definitely test the monitor, either with onboard video or on another computer. If you have a friend with a monitor, I'd even suggest trying another monitor on your machine (i.e. you don't even know if the machine is running properly without a display).

You indicate the machine was working properly before you changed out the memory. Have you tried to go back to the old memory modules to see if it makes a difference?
