PC starts up fine, connects to interweb, runs word processing and most internet browsing, but when a more intensive program is launched, it'll just shut down. games, Pshop, even streaming video. I was originally told by some friends that my power supply was inferior, and could not support the graphics card, so I dropped the last of my 'spare flow' on 200w upgrade. no change. should I brave another upgrade? is it a problem with the card? is there some kind of obvious problem that I should feel bad for not knowing about? Motherboard - ECS Black a790GXM-AD3 CPU - AMD Athlon II x2 250 Video Card - Powercolor AX4850 1gb PSU - Sunbeam 680W RAM - (2x1GB) OS - Windows 7 64b This was my first shot at building a PC. I'm an illustration student and they've been forcing apple down our throats, but macs are like cats- you can't play games with them, and they'll never really love you. Everything was going great, and then I tried to run... you know... programs.
