My Win7 computer will not boot. It never even gets to the user selection screen. It stays stuck on the logo screen that comes up before the user selection screen. Every few seconds the screen will flash. Sometimes, if I let it run for a while like this the screen will just go black and stay there. Other times it stays in that logo screen flickering every few seconds. It will also not boot into safe mode. It gets stuck in the same place, before the user screen comes up.
Multiple scans with chkdsk and sfc revealed no errors and startup repair found no errors. Tried last known good configuration and that did nothing. Full memory scan showed no errors. Tried system restore from a boot disk, but it could find no restore points, which seemed odd to me since I know I have several restore points. Tried running system restore both from the repair admin command prompt and from the install disc. I'm out of ideas.
It's an older system, Athlon X2, 2Gig Ram, The boot drive is a RAID 0 array of dual 500GB SATA drives.
