Here's my setup: Video Card EVGA nvidia GeForce 9800 GTX+ Creative X-Fi Extreme Fatal1ty Pro Series ASUS P5Q Pro Turbo Intel Core 2 Quad 1TB w/ multiple partitions Other JBODs for storage 4GBs or RAM Win 7 pro 64-bit Previous OS: Win XP pro 32-bit 1. I did a clean install from XP 32 to W7 64 on the partition that had Win XP 2. Successfully installed W7 and started adding typical windows update 3. Updated drivers for Video and Sound cards 4. Installed my Norton 360 premier edition after leaving my PC on for a while, it went to sleep and I could not wake it up without doing a reboot. After reboot W7 tells me to do a CHKDSK. After it does it thing, I can get into W7. So I turned it off and then on- AND I get the CHKDSK issue again. Even my Norton 360 tells me my C drive has some "file system errors". Please help. If I can't get this resolve- I'm going back to XP and wait out for "the W7 service pack".
