Hi everyone., This is my first post so be gentle with me! I've got a Packard Bell iMedia M848 with the following: Micro ATX Sis 651 Intel® Pentium® 4 Processor 2.8Ghz with 512KB L2 cache 1x AGP (4x) 1Gb RAM Benq 17" LCD Running Windows XP SP2 I've just replaced by old Radeon 9200 (128Mb) for a Sapphire Radeon 9550 256Mb AGP card and when the card is seated and the PC re-booted, I get no signal to the monitor at all. The PC boots up okay (you can hear disc activity) but there's nothing to the monitor at all (theres' no POST even!). If I replace the card with the old one, all fine. If I take out all cards and use the on-board VGA, it's all fine. I removed all previous drivers before I installed the card. Can anyone help? Is it a bad card, or have I got the wrong card?
