Hard Drive Help

[Confused X 2]

I just installed a new hard drive in my computer. The original is a 60g and the new one is 300g. I copied the old hard drive to the new one and set the new 300g as master and the old 60g as slave. I now get an svchost.exe application error box with 0x7c901010 memory could not be "read". Also, windows will not shut down. I have to unplug to turn the computer off. Would it be better to set the 60 as master the 300 as slave. Should the larger hard drive be the master. Also I did something wrong because the drive letters are wrong. The new one is F and the old one is C. Any ideas on what I should do?
ps. I know just enough about computers to screw one up really good so don't assume that I know the basics.

dell customer support is usually pretty good with these kindsa things; but if you can't get ahold of anyone that knows how to deal with your issue, I recommend NOT copying one drive to the other, instead, backup your personal data and perform a fresh install on the new drive.

Thanks for the info. I was just trying to keep from the hassle of a complete install. Guess I'll try to find my install disc.
