My present PC's specs are:MB: D102GGC2 with onboard ATI Radeon Xpress 2002 GB DDR2P-4 3.0 GhzIts about two years old. The problem is that when I tried to run Windows 7 on it, there were a lot of problems. First, the Aero theme would simply not start. Then I found a driver after a lot of searching, and got the Aero running, but if I start an HD video, the graphics card crashes - it gives a message that the driver stopped working and was started successfully. Sometimes the computer just freezes with coloured lines all over the screen. Also, XP mode won't run because the PC has no hardware virtualization.I run mainly XP so it isn't such a big problem, but I'm buying another PC, for home, and while no one is going to play games on it, I want it to run Windows 7 smoothly, and I want it between 15 and 18K. My assembler has suggested the following configuration:MB: Biostar G31D - M7P-4 2.8 Ghz HT2 GB DDR2 RAM18.5 inch HCL TFTand the other stuff.Will this config run Windows 7 properly? The MB is not Intel, so I might get an Intel original one instead. I also asked for dual core, but my assembler says this HT one is better. Please advise.
