ok, my computer freezes up in games made in about 1999 and onwards (mostly fine with fallout, but not fallout tactics...), especially in menus, but is fine in the demos of half-life 2 and doom 3. It's done this ever since I bought it. it runs fine until suddenly freezing, then usually beeping and going black after a while. sound begins to loop. It's a pentium 4 2.0 ghz, 512 mb RAM, geforce 4 mx 440, running XP home edition. I've tried updating the graphics drivers but that's made no difference. it would be a perfectly decent machine if it would only work! OH THE HUMANITY! I don't know that much about making these things work. Should I update the motherboard or something? I'm terrified of doing anything to the BIOS...
