I am having ongoing problems with my computer freezing, and then sometimes 'crashes' and a message pops up that says intel graphics accelerator for windows 8 (r) stopped responding and has been successfully recdovered. Is this wird that it says windows 8 when I'm using windows 7?

I have a Old Dell 2400 Im working on.. its has 2.40 ghz with 2gb memory. I installed a New hardrive (20 gb) and a dvd-rom drive I took out a cd rom.. I was planniong to install Windows 7.. But before I can do that The comp prompt me that thers NO DRIVE FOUND on either.

I a PowerVault 745n Server, with a factory hardware RAID setup. Recently, both arrays 1 & 2 failed. O/S hosed, and Data on on array 2 can not be accessed. I have found backups for most all needed data, however, I cannot access the raid's data. I plan to just reinstall the system.
