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.
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.
