    I've reinstalled this again and again, repaired with the disk, I've moved RAM sticks already. I will now run check disk command from the recovery console. I'll keep you posted. Thanks

    Didn't seem to work, no sectors were bad, nothing was corrected. Any other suggestions? I"m thinking of running a killdisk on the drive and reinstalling it again.

Try resating the memory modules on the system. check with each memory module one bu one.
If the problem is still there , check the harddrive for errors or bad sectors .

My Acer aspire one wont start into normal windows, only safemode

Did your system come with any software? I know when I bought my aspireone it did not. However, You can purchase a thumbdrive with at least 4 gb of space and if you have a copy of windows xp of the same version as that which is loaded on your aspireone (should be windows xp home edition) and you can use a program like magicISO to create a copy of the windows xp cd onto the thumbdrive.

Hope this helps, and I would be more than happy to give you more specific support as needed.

Good Luck!

My problem is identical as what is mentioned above. MIne says that "ACPI multiprocessor pc hardware is not recognized by Windows logo. Install anyway?" Should I install it

ACPI is a setting on the BIOS.
If you have problems with it, you can safely disable that option.

Installing xp freezes

If it will only boot in safe mode it means you have a driver conflict.
This is only a suggestion but try fresh reinstalling windows, with only basic xp drivers then install other drivers one at a time rebooting each time you do until you come across the faulty one. remove it or check its for xp not vista research net for correct one

ACPI Multiprocessor PC is trying to install on my friend's computer. It started ocurring after she did system recover. It looks like she now has two hard drives -- one fat32 (?) and the regular drive c. At...

YES, do let it install !

ACPI stands for Advanced Configuration and Power Interface

This is a firmware interface in BIOS, that allows operating systems to call BIOS routines for managing power related
system hardware parameters:

1) CPU mode (Sn states): Run, Suspend, Sleep, hibernate ...

2) CPU Voltage and frequency

3) Fan speed... etc....


Multi-processor PC, means that the firmware has detected a
multi processor system or is confused by the hardware. There
are several conditions that cause this interpretation:

a) A genuine multi-CPU Board with 2 or 4 CPU sockets.

b) A multi-core, single CPU, such as the new Intel
CORE-2 DUO series...

c) Interleaved RAM on a single CPU, with dual buses.

This is OK, and nothing to worry about.


The ACPI interface is very advanced and complex, about 3500
pages of engineering specifications, and most P'sC only use
a very tiny sub-set of its capability.

The ground level ACPI settings and options are contained within
the system BIOS. The best solution is to set them to their
default settings, unless you know what all the settings mean.

To access the BIOS settings, on most PC's:
Press DEL or F1 right after the POST/memory test.

Depending on the BIOS settings, the operating system's HAL
(Hardware Abstraction Layer) may need to install additional
interface and control drivers.

On a desktop, these so called "GREEN" power saving features
are a horrible pain in the neck. and I would disable them all
together, unless you pay $20,000 per months for your

On a laptop, however, these drivers are fairly important to
significantly extend your battery life, so you should enable

If the computer was restored to factory condition, by pressing
a magic "blue" button, these drivers are part of the original factory installation and should be installed, just let the PC recursively do its thing, until it calms down.


Most name brand manufactures provide a hidden partition on
the hard driver, typically a FAT-32, which contains a complete
set of recovery files, unique to the PC model and all the features
it supports.

This restore partition is most often formatted as FAT-32,
because FAT can be accessed using primitive BIOS calls
while NTFS cannot:

1) FAT16 = Original DOS, support drives < 2GB only.

2) FAT32 = Extended FAT-16, for larger drives.

3) NTFS = Windows NT, 2000, XP, and Vista only.
Cannot be accessed before Windows is running.

The manufacturer then provides a boot/ BIOS hook,
activated by their MAGIC or BLUE button, which in turn
un-hides this restore partition, loads Windows PE
(a special pre-install/ repair version of windows),
and then loads the recovery program.


In any event, you need to let the installation/ restore process
finish, including the ACPI install.

After several annoying re-boot cycles, this process will (should)
restore the PC to original factory conditions.

Factory restoration is, however, a very drastic and destructive process. All your settings are lost and (depending on the particular system) sometimes your data as well. I should
be avoided like a biker on a bad day.

It is a good idea to back-up everything possible, before taking such a drastic step, and I prefer to use an external USB drive for doing this. Also this step should only be used as a last resort.


However, in your case, all the DRASTIC and LOSSY part has
happened already, so you have no choice but to proceed and
let it finish. Once the restoration is complete, the FAT-32
partition should disappear, that is it will be hidden again.

Do not damage this partitions, unless you own a set of factory
repair CD's !!!

It is also a good idea to request the FACTORY repair CD's for
your machine from the manufacturer and keep them in a safe

Once you have the recovery CD's, you can delete the hidden
recovery partition, and use the recovered space for more
useful things, such as data or applications.

To do this, you need a partition manager tool, such a Norton's
Partition Magic or Acronis tools. Norton's bought the original
tool from Power Quest, and royally phluquified it, so I much
prefer Acronis these days.


Also after you PC is fully restored, go into the power settings
in the control panel (or via the screen saver settings) and
configure the ACPI as you wish. But you must install it first.

Hope this answers all your questions,
please rate my answers.

Fail to load files during text mode setup

Maybe its a software problem, have you tried putting in a bootable XP installation CD? After the bios boot and it asks you to boot to CD, press R for repair, it will try to repair your OS, and if it is an OS problem ,then it will boot once again... If not you can try formatting your HDD and reinstalling windows...

OS load failure.

The bluescreen saying about the ACPI, I had the same problem at work with a older computer. Next time you get the bluescreen read everything it says.

It tells you to press a button, I'm not sure thats why I'm telling you to read the bluescreen (windows 2000 or xp) it was f5 or f8.

You press f5 or f8 I think it was f5 since f6 is to load custom drivers.

So you press f5 when it asks you to press f6 This disables the ACPI subsystem in the setup and you should be able to install windows 2000 without any more problems. If its not f5 read the bluescreen thats where I got it!

Good luck, keep me posted and tell me if theres anything else.
