What do you mean by "a weird HDD scrawling at startup "? After you boot up and log in, go to spotlight and search for disk utility. Select Macintosh HD on the left and click on verify disk. You might also want to install Onyx to clear your cache and other useless items.
I need to know some of your specs
1) How old is your mac and what is your current version?
2) What is your ram?
Important Notes: Clearing the PRAM does not always help and could even harm your mac. Slow startup could be a sign that your hard disk is going to crash or fail soon.
Your hard disk has crash, you need to get a new hard disk. Try sending it to a local repair shop and have some expert to closely look at it.
Do this steps
1) On your mac and insert the Mac OSX Installation Disk into your mac mini
2) Restart your mac and hold down the option key as it boot up again
3) Select the disk and choose your language.
4) When you enter, remember do not reinstall snow leopard at the top of the screen there will be a utilites bar something like that.
5) Go and search for disk utility and use it to repair your hard disk. After you are done, restart your mac but this time boot up from the internal hard disk.
See whether that works, if that fails most likely you need to get a new hard disk for your mac. Send your mac to an authorized apple store and get the technician there to help you fix.
Instead of hiding your dashbard in login items in system preference, delete it instead. It won't harm the dashboard app. Your dashboard may start slow due to a lot of widgets in it, low ram or less hard disk space left. Try downloading onyx and run it. Restart your mac and see whether your dashboard takes long to start up.
By the way how do you start up your dashboard? Pressing F4 or clicking on the applications?
It also depends on the brand of the laptop. I suggest that an i5 processor will be good enough. Unless you are doing what flagstar said above. 4GB ram and 500 GB hard drive will do and 1 GB graphics. Good luck
Use the power cord instead of the battery, have the battery removed and see whether your laptop works with only the power cord. Can you charge your battery. If no, battery is faulty and need to replaced soon. How old is your battery?
You are right about the Motherboard being from an E-Machine. If you have spare HDD, put in some data into it ( Not important ) and try it with the Imperial motherboard. Use the emachine cd and try reinstalling the HDD and see if that works.
