Here are my system specs: Intel Core 2 Quad 8200 Gigabyte EP43-UD3L mobo 2GB DDR2 Corsair memory sticks WD 160 GB SATA HD EVGA GeForce GTX 285 1GB with GPU Apevia 680w PSU and P4 12v ATX adaptor for CPU Sony DVD Drive and CD ROM that are on the same IDE cable but jumpers might be wrong So far I have not been able to notice if my graphics card is working or not, when browsing with IE it seems sluggish when I scroll up or down. Well, with Firefox it seems faster but I have had problems installing drivers for my EVGA graphics card. My HDD light stays on for lengths of times, then goes off, but then comes back on for a while. Could the Bit series be the wrong install for my system? Can I downgrade to 32-Bit?
