Hi, I recently replaced some bad hardware with the same components, but new from Microcenter. I installed all the components, and my computer turns on. It flashes the BIOS page, then quickly goes to a windows startup page. The options on that page are: Start windows normally OR run system repair. If i run system repair, it can't fix the problem and shuts down. If I start windows normally, it freezes in the startup animation and brings me to the BIOS page, which quickly flashes into the windows startup page.
At least I can get my PC working now, but can't get to anything

First Clear CMOS, unplug the PSU for 5 minutes then switch the CMOS jumper 10 seconds; see - http://www.youtube.com/watch?v=rdHH9KrceR0 if possible boot in to the BIOS and Load 'Optimized' Defaults and save; see your manual.
