Thankfully, the geniuses over at Apple have made the process easy for us—no need for a disc; no need for a drive—all you need is a decent internet connection. With just a few clicks of some buttons and your Mac is gonna be running like it did the day you got it.

Best of all, this will work with Lion,. Step 1: Back Up Your Files! Okay, so you may have a lot of files that you want to get rid of, but you definitely have some files you want to keep.

Use a writable CD/DVD, a, or any of the multitude of cloud options to keep your important files backed up. You could also create a Time Machine backup, but I wouldn't do a full restore later—just pick and choose things you want back after a fresh install—otherwise it could run just as sluggishly or erratic as it did before.
Step 2: Restart Your Computer Once you've double-, triple-, and quadruple-checked your backups, restart your computer. Step 3: Press CMD+R The second you see a grey screen, hold the CMD and R keys down for about 15 seconds, then let go and you'll be taken to OS X Utilities recovery. PLEASE HELP!! Whenever I turn on my iMac, it would load up to the apple logo and shut down after a few seconds. This happened ever time i tried to turn it back on again. I had a bit of hope but nothing ever changed so I decided to erase my disk and was immediately promoted me to restart my computer.
When I did, it brought me a a symbol of a folder with a question mark which flashed forever. I held the power button to turn it off and hit it to turn it on again while pressing command and R keys at the same time, it brings me a sign of a spinning globe that loads forever. When I restart it and immediately insert its installation DVD while pressing key C, it brings me the apple logo and stays like that for ages. This is freaking me out.
