Query: Display/Network Woes Presario 6010us

Picked it up about a year ago, and it worked ok. However, when upgraded memory with PNY pc2100 512mb x 2 dimms, the computer has random lockups, video degradation and just generally unstable performance. Freezes playing dvd - and before that has a lot of random horizontal lines going all over the screen, spontaneously reboots while downloading from the internet via the network connection.Memory has been tested and is known good. Motherboard and hard drive were replaced at an authorized facility and still the same results. I think it's the MSI's realization of NForce chipset, and I may be SOL. Definitely annoying and unworkable.Support is difficult to get and wastes a lot of your time before getting you permission to ship to a repair facility. So, stay away :)
