Operating system: Windows 7 32-bit (i'm aware of the 4gb RAM restriction here)
Display Adaptor: NVIDIA GeForce GTX 460 vram 1gb
Processor: AMD Phenom(tm)IIX4 965
HDD: Hitachi HDS723020BLA642 ATA device
Motherboard: Biostar a870
DVD.CD-ROM Drive: TSST corp CDRWDVD TS-H493B ATA Device
RAM: Kingston 2GB 240-Pin DDR3 SDRAM DDR3 1066 Desktop Memory Model KVR1066D3S8N7K2/4G x 4
(This was my original set up)
Crucial Ballistix Sport 4GB 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10600) Desktop Memory Model BLS2KIT4G3D1339DS1S00 x 4
(this was gonna be the new setup)
I wanted to upgrade my RAM from 8gb to 16gb. After trying to put in the new RAM, the Crucial, my computer started to go very slow. Slow, meaning, taking ten minutes to start up and programs taking forever to load when clicked. I tried then to put my old Kingston RAM back in and it still booted up slow. The old Kingston RAM has never acted like this before until the Crucial was put in. I'm at a loss here.

Try to install chipset drivers from CD that came with motherboard or from Biostar support site. I had similar issue once and this helped.
