USB and iSight not working

Hi, I've been having some issues with my macbook:

(1) My front USB port is not working. I've been getting the following message everytime I restart (even when nothing is pluged in): "Becayse a USB devide was drawing too much power from your computer, one or more of your USB devices have been disabled". I've tried resetting the PRAM and SMC, this does not work.

(2) My built-in iSight no longer works. I tried using skype and photobooth and the camera is not detected. I looked in my system profilers and isight is listed but I'm not sure what this information tells me (see below):

Built-in iSight:

Product ID: 0x8507

Vendor ID: 0x05ac (Apple Inc.)

Version: 4.42

Serial Number: 8TA5B04NPDCJ6F00

Speed: Up to 480 Mb/sec

Manufacturer: Apple Inc.

Location ID: 0x24600000 / 2

Current Available (mA): 500

Current Required (mA): 500

(3) My battery drains when my macbook is in sleep mode (this was not happening before).

(4) My computer seems to be getting really hot. This cause the bottom rubber of my macbook to start peeling off. I've downloaded iStat to keep and eye on the temperature but I'm not sure if this is related to my other issues.

Does anyone have any idea what could be causing this? Are there any tests I can run? I'm not sure if these issues are related or not. Please help.

MacBook (13-inch Mid 2010), Mac OS X (10.6.8)

Your symptoms suggest to me that you may have a hardware problem.

Consider the troubleshooting tips in http://support.apple.com/kb/HT1151

If that doesn't help you, contact Apple or an Apple-Authorized Service Provider ASAP to have your Mac checked out.

Thanks EZ Jim,

I went through the troubleshooting tips but nothing works.

Do you know if there are any diagnostic tests for hardware problems? I tried restarting and holding the D key but nothing happens when I do this (and I don't have any of the CDs that came with the computer with me).

I live a few hours from the nearest Apple Service Provider (and I am no longer covered under the warranty) so I would like to try everything I can do myself before bringing it in... any suggestion are greatly appreciated!

According to the AHT instructions on p. 61 of the manual for your 13-inch Mid 2010 MacBook, http://manuals.info.apple.com/en_US/macbook_13inch_mid2010_ug.pdfyou did the correct restart process. To me, the fact that AHT does not work either is one more indicator of likely hardware trouble.

If nothing else you try fixes your issue, try restoring your Mac's software. If neither a Time Machine restore nor a complete restore to factory original condition (p.60) corrects your trouble, I think you are left with the choice of AASP service or deciding whether it is time for a new Mac.
