update to the latest flash
if this doesnt fix your issue then your processes are using alot of CPU try to turn off any CD burning applications or anything that uses the CPU alot also if you want to see what exactly is using alot of CPU press Control Alt Delete and if it asks pick task manager, then click the processes tab and see whats using 100% system idle process is fine, also if you dont know the program thats using alot of CPU do a malware scan with a program like spybot or adaware

Theres is a lot of reason associating to a black screen. First lets just assume it the screen and not the laptop. Check to see if you still see any image in the screen, you might want to do this in a lighted area. If you do, but is very dark, then your backlit light is dead and your screen needs replacement. If you don't see anything, then use a external monitor such as a computer monitor, a Tv and connect via VGA port, or HDMI if you have one or a svideo to an external souce and see if you get picture, If you do, then your Inverter is bad, or either a loose connection wiring somewhere between your comuter base and your screen. ( Because laptop tend to open and close alot) If you don't get anything via external source through your VGA, HDMi or s-vdeo, then this is something involved with your laptop. Could be from cpu, chipset, ram, or simply the motherboard itself.

try going onto itunes and connect your ipod to your comuter or laptop and press restore to factory settings it will be like brand new

Here are a table of Max CPU temps ->link.

You need do grease the cooler with car oil. Then it will be ok.

that is most likely due to too many apps starting up at the beginning...can you sort that panel by cpu usage, and see what are listed under the user account. be careful NOT to do anything with the system files

In a nutshell it is hard to say for 100% certain without the model number from the motherboard.
If it is even remotely recent, then it will be no problem at all. Anything from the last few years is safe.
