you could try using BlueScreen Viewer to gather details of the BSOD (STOP error) to be sure it's a hardware problem. A PCI based sound card is a good option, if you're planning to get a really good sound card.

If not the HD6950, the Geforce GTX560 Ti is the card to get.

Hi there, As a representative of ReviverSoft, I would like to point out how Driver Reviver can be useful to most users: 1. An easy, two step process of updating ALL your computer device drivers. 2. Automatically creates backups and Windows System Restore points during driver installation. 3. Ability to backup and restore drivers to custom locations when required (Coming Soon) - Identification of devices that are missing drivers While other options do exist for computer users, it's really the convenience that you pay for. Again, we encourage users to try their hand at manually updating the drivers on their computer. Cheers, ReviverSoft

To answer your question: 1. Yes, the onboard graphics chipset will consume memory from the System Memory pool (3GB) 2. No, the onboard chipset cannot use the dedicated card's video memory If upgrading the RAM (system memory) is an option, I would suggest upgrading to 4 or 6 GB which works great for a 64bit version of Vista or 7.
