PowerColor x800 memory dumping on LCD

Silver_Seagull · Mar 24, 2006, 02:56 PM

Hey all, hope you can maybe shed some light on this-

I have a PowerColor ATi x800 256MB DVIx2-out card in my PCI-E x16 slot.

Every time I connect an LCD that has a VGA connector to the card (through the supplied DVI -> VGA cable adapter) it crashes the system to a memory dump and restarts.

I've tried it at boot and on the desktop- every time it detects the display- mem dump.

The monitor works like a charm on a CRT (with a VGA cable through the adapter) on display 1 and/or 2.

Help! I want to move to an LCD screen....but this is not good news :/

Try plugging the LCD into the card directly with no adapter

I can't- the LCD has a VGA connector, and the card only has 2 DVI connectors.

If you have a ohm meter, ohm out the ground on the power plug on the monitor to the metal screws on the monitor cable. They should be less than 5 ohms. If not, you may have an open ground. I had a problem with this bluescreen/rebooting whenever I had my mp3 player charging and I plugged in the USB cord to the puter. I solved it by making my own ac adapter that the negative output on the ac adapter was grounded to the third (green ground wire) prong on the three wire grounded plug and presto! problem was fixed! You may also try attaching your own ground directly from the monitor connector to ground too. Hope this helps!

It's not a grounding issue- the monitor works fine on other computers. I even plugged it into a known-working grounded plug, no dice.
