         I have a laptop I want to maximize my laptop battery’s life how can it possible?

I am not familiar with replacing graphics card. And I would want to know few things about:

a.) a website where I can post computer specs so I can post them and if I can install my old 7600 GT Nvidia to my new computer

b.) Which graphics card is better to use, a 7600 GT or a 9300 GE? Will I end up messing with the 9300 GE in any ways?

c.) and lastly, how can I uninstall the old graphics card then install it to the new one.

Thank you.

 There is a un excepted noise comes from my computer, how can I solve the problem. Please help.

I have my new computer and everything is running smoothly. Except that some games like crysis has some issues and cannot be played easily. I think the problem is with my new graphics card GE 9300. So how can I revert with my old settings even if I have my new graphic card? Or how I can resolve this? Please help.

Here is my problem and I hope that someone would help me figure things out.

I have my old computer with 7600 GT Nvidia card. I can very well run Crysis and some other high definition games with it. Even though sometimes, it will take a while before it loads up. I know this is likely because of low RAM.

How can I fix it? Help please.

Frequent shutdowns, I7-950, where to start?
I have an Apple DX58S0 and i7-950, NOT overclocked, created about 18 several weeks ago and has been firm.
The last two shoes after it was off and freezing it has totally reset itself every few moments. It operates for a while (increasingly extended each time), then reboots.
There are no components issues in the bios, there are no function log items of desire (other than the "was unexpected"), there are no obvious symptoms and symptoms on the display, and no beeps or uncommon tones. I ran the CPUID Hardware check once and as it totally reset conditions were great and standard (mid Fifties c). It is basically as though the totally reset switch was hit.

I purchased Dell Inspiron 1525 14 months ago. Just recently, it stops booting but the power lights are on and activity lights blinks for about 4 seconds.  Supposedly, the media light will flash together with the activity light, it goes out but the power lights are still on. I tried all the command keys but the screen is still black. What do I need to do? Help please.
