Recently, when trying to start the machine, it developed this problem: During booting it would flash this statement on the screen: autocheck missing. The machine would then restart and continuously repeat this cycle. Tech support suggested I place the harddrive into another machine and download files if I want to save them before using the restore disk. My son swapped it into another emachines but, of course, since the software on the 2958 harddrive is the problem, it remained. While replacing the harddrive back into the 2958, the power problem developed (see my other posting). Any thoughts?
It sounds like there may be an issue with the memory chips. If available, take a memory stick that matches the type of memory you need for your computer. Take out all memory sticks on the motherboard and try the new memory stick in the first memory slot and see if you get the error. If so, then try it in the second memory slot.

It seems your boot image has been corrupted. Pleas try following methods.
1. Go to BIOS settings by pressing F2 during boot. Insert portable OS flash drive in to USB slot. Then select boot from external storage. This will run your portable OS and take back up of your important data to other hard drive. Then reinstall OS image.
2. If you are using windows OS, go to startup system repair option during boot. That will restore your system.
Boot into Safe Mode by pressing F8 during boot and...
disabling startup programs. Go to Start > Run (search in Win 7) and type
MSConfig. In Startup tab, uncheck anything that you don't want Windows to
load automatically. It will make Windows boot faster and use less resources
while running. This just disables them in startup. Programs will still load,
but when only you initiate.
Hi, try pressing the ESC key during bootup, this will give you the option of starting in safe mode, from where you can roll the clock back on your operating system to a time before the problem started. Hope this helps
Restart your mac. As it's restarting/booting up, hold down the command, option, R and P keys simultaneously. As it's booting up and you're holding these keys, you should hear the startup chime, continue to hold the keys down, it will cycle and you'll hear the startup chimes again. Let it go thru this cycle 7 (seven) times before you let up on those keys. Once it's cycled 7 times, let it boot up normally.
If that doesn't work, then reinstall the original system software that came with the Macbook. You may have to reformat the hard disk and do a clean install.
