I think, the problem might be cause by the operation system. Did you try remove system and install a new system ?.

nope, what im thinking happend is that maybe, it was trying to update overnight and the battery died while it was updating. because when i was on it the day before it was asking me to update now or postpone n i hit postpone. if that is the prob. how could i fix that?

Hi,

Shut down the notebook.  Tap away at f10 as you start the notebook to enter the bios menu.  Under the Advanced or Diagnostic tab you should find the facility to run tests on both the Hard Drive and Memory.  Post back with the details of any error messages.

Also post back with the full version of the operating system you're using - ie Windows 7 64bit.

Yes I tried both the hard drive and memory test both passed with no errors. I'm not sure how to figure out what bit I have but product number is x5698ua#aba

Hi,

Can you double check the Product No. you've posted - this is normally Two letters - Three numbers - Two letters ( ie XE274EA ), you can ignore anything to the right of the #.

Hi,

No problem

If you don't already have one, use another PC to create a Windows 7 Rescue CD.  Download the relevant ISO from the links below.  If you're not sure of the version, the product page for your notebook indicates it was shipped with the 64bit version, so try that first.

Windows 7 32bit

Windows 7 64bit

You should use an application such as ImgBurn to burn the ISO to a CD - a guide on using ImgBurn to write an ISO to a disc is Here.  Once created, or if you already have this, insert the Rescue CD into the notebook and restart to boot from it.  Select Repair Your Computer and choose the Command Prompt.  When this loads, enter the following commands and hit enter after each one - include spaces as shown.

Bootrec.exe

bcdedit /export C:\BCD_Backup

c:

cd boot

attrib bcd -s -h -r

ren c:\boot\bcd bcd.old

bootrec /RebuildBcd

bootrec /fixmbr

bootrec /fixboot

Remove the Rescue CD and try rebooting the notebook.

Let me know how it goes and if there are further error messages, include them with your next post.
