Hello all, I have a Dell OptiPlex GX520 that seems to be working all lights come on no beeps from systems but can't get a picture anything that helps me get a picture would help. I have already tried resetting the BIOS, changed hard drive, changed ram and still no picture. would placing a graphics card bypass the main graphics chip or not. without seeing anything I can't get in to set up drivers for anything nor can I see the bios to make changes.
Yes if you install a graphic card it will bypass on-board graphic chip.
if you dont have 1 borrow a friends first just to make shore its the problem...........dt
great response, it worked but I am now hearing make some nasty shock noises upon looking a bit closer its frying caps so its toast... Thanks for the help but I am building a new computer now, as for this one is old and no longer worth even spending a few bucks on cap replacements. Thanks again

maybe try taking out the cmos battery located in your case, looks like a small watch battery, that will clear bios settings and start from scratch, if there is no battery then there is a jumper sequence to do this
SOURCE: Bios default password
The BIOS default password is just blank, and it is not asked.
When you set a bios password, you are asked to enter a value, therefore if bios is asking the password, the password had been changed.
To reset the bios password if you do not know the password you need to access to motherboard and temporarily remove battery for few seconds.
Removing battery will reset bios and delete the password.
Unplug power cord before accessing the motherboard, and try not touching the motherboard with your finger.
Put battery back in place before restarting computer.
