I Recently purchased a new motherboard and some ddr3 ram (BioStar A770E3), my computer has worked fine, I put those two into my case swapping out the old with the new. My problem is when I go to try and install windows from the CD drive, the installation hangs at disk.sys, along with I can hear the cd drive stop spinning. I've tried setting my drive from slave to master, only having 1 4gb stick of ram in, pulling out my audio card, and swapping to an older graphics card. I'm out of ideas, and I'd really like to get my system back up and running, not to mention I'm a bit frustrated that I'm yet to even see if my purchased were worth while. If anyone can help that'd be great, I'll post any info you guys need as long as you ask for it. Thanks for any help I get, hope to hear from someone soon.
