monitor won't connect?

by MelanieCM / July 27, 2007 11:14 PM PDT

hi I have an e machine computor T2825,AMD athlon XP processor 2800+,120gb,512mb,NVIDIA graphics. windows xp on dsl.
I typically shut down my monitor at night, sometimes I turn the entire computor off.When I turned the monitor back on it showed a yellow,green,and red message:
self test G
check your pc
+ signal cable R
monitor working B
this happened once before and I replaced the monitor and it was fine after that. This time I replaced the monitor with a used one and the screen remained black,so I tried my daughters,that I was certain was functional and still got a black screen.
I am now connected through a friends laptop. Any suggestions? Ive checked all external connections so far.
Thanks in advance for any help.
Melanie

On-Board Graphics Bad?

I'm assuming you've checked that the PC appears to be receiving power and attempts to boot up (fans running, power light on, HDD activity light flashing)? Your NVIDIA on-board graphics may be bad. You may have to have the entire mainboard replaced. Another option is to try installing a graphics card in the spare AGP slot.

I'm sorry I'm not sure what a graphics card in a AGP slot is?
Thank you

Graphics Card
by sunwatcher / July 28, 2007 3:09 PM PDT

Your computer (according to the e-machine's website) has the graphics processor built into the mainboard. It can also accept a separate graphics circuit board that will plug in to the mainboard. My suggestion was to try using a graphics circuit card in this slot, but this might be beyond your comfort level.

Do you have anything at all displayed when you first boot up your computer? Normally you would see text indicating the BIOS version. If you have absolutely no display when booting, then you are most likely going to have to open up the computer case to make sure no connectors are loose, and that you have some indication of power to the mainboard. The worst case scenario is that you will have to have the entire mainboard replaced.
