AGP video issue on older PC. Compaq d530C tower 3

[atascoman]

I am trying to upgrade the video on this PC. It came with the onboard Intel adapter. I have troed dosabling the card in device manager and could not find an entry in DOS to disable the card.

The card I am trying to install is a ATI Radeon HD3650 AGP 1GB. When I install it, neither adapter will power the monitor. Anyone seen this or have any insight on this PC model. HP support was no help.

May be an issue with the power supply, looking at the specs for the video card it requires a 300w power supply, and the HP only has a 240w power supply.

Does the Compaq motherboard offer a jumper for disabling the on-board video?

Also, look in the BIOS to see if there are any settings referring to on-board or AGP video adaptors.

ATI video cards seem to be 'upset' very easily by even small static charges. Make sure you and the computer chassis are well grounded before inserting the card. Also, earth all the AGP (gold finger) connections on the card itself before inserting it into the slot.

THanks, I will try the power supply. I could not find any jumpers on the MB, and there were not settings in the BIOS for it either.

I have an older HP and your issue may be similar to mine.
Go into the BIOS and see if it recognises the card in there.
If it does, set it to primary or similar.
Next look for something like halt on errors and set to disable.
See if that does the job.
For some reason, even though the card is set up as the primary card, it throws up an error believing nothing is plugged into the onboard card so halts. However overiding the setting, it will eventually throw the windows start up on the new card.
Sorry bit vague, but not on that pc at the moment.

Ran across one with shared memory that required the shared memory to be set to 0 before it would ignore the built in adapter.
