I bought a used Compaq Presario CQ62 for cheap, and went to install windows on it. I formatted the partition and went to install when I got this error....

Windows cannot install required files. The file may be corrupt or missing. Make sure all files required for installation are available and restart the installation. Error code: 0x80070017

I have used this disk before with no problems, but internet searching suggested I burn one at 2x speed because that helps for some reason... I'm burning one now, but my question is, why would I get this error, OTHER than the disc being bad? I'm pretty certain this one isn't as I have used it before...

(ok so the slowly burned cd (using imgburn) didn't work either so it's DEFINITELY not the disc)

Thanks in advanced for any answers

Also I took one stick of ram out because internet searching also suggested that, but it didn't make a difference.

Also I ran memory and hard drive checks and they passed fine.

Also I reset the motherboard options to default

What could it be!? Help I'm completely stumped...
