Or you might have to change to a more powerful power source. If you have a Battery designed for low power consumption, you will experience Battery drain.

What is the optimal temperature for a GPU?
The maximum "safe" operating temperature is 90 degrees Celsius. however, it should be well below this for the most part. most run from about 40 degrees idle to mid to high 80s under load. However, for serious overclocking, the lower the better. There are systems that lower the temp to close to -273 degrees which is close to absolute zero. This is the point at which matter no longer moves (all matter is constantly vibrating, you just cant see it)
The Display settings are set from the Displays section of System Preferences with Mac OS X.

How do you overcome fragmentation problems?
This depends on how you mean the question. When fragmentation occurs, the solution would be to run defragmentation software.
If you want to reduce fragmentation from happening, there are a number of workarounds. One would be to schedule defragmentation or to use software that constantly defragments in the background when no user activity is detected. Another workaround would be to divide the hard drive in partitions and edit the registry to point all the temp files and cache files to it. That would not reduce the defragmention, but it would be faster since all the worst fragmented files are all in the same partition.
Or you could switch to a SSD drive. Yes, they still get fragmented, but fragmentation doesn't increase their wear and tear nor worsen their performance. If you have a SSD drive, you should rarely defrag it, and you should reduce writes to it where possible to help it last longer.
What would stop a computer from loading?
