hi

i have a DELL computer which had no recent problems. yesterday i unplugged it to install a new audio device (ESI maya44) and when i try to light it up again the indicator stays orange (it usually stays orange for about 2 seconds and turns green but now its always orange)
the keyboard and mouse are REACTING but the screen remains black and nothing happens.

the computer was extremely DUSTY when i opened it to install the maya, and i cleaned it, but still it doesnt work.

any help please? im no expert so please try to make clear instructions without too many sophisticated terms....

thankshow do you know if the keyboard or mouse is reacting without display?
try taking your new audio card out just to test
maybe hardware conflict
make sure you DIDNT knock a plug loose when you were
insideUninstall the Maya and see if it's back to normal....did you dislodge ANYTHING inside while installing it ? ?
I'd re-seat any CARDS you have and the RAM.

As always when working inside the case remove all power sources and take static precautions...
