I have an acer aspire 5742 ....the problem is when i turn my laptop on shows acer logo during POST and then restarts again ....i tried pressing f2 to go to system settings but system settings do

I know about computers and understand that my hard disk has malfunctioned .......actually i was running about 10 different tasks and watching a movie too got stuck (vlc media player) when i tried to forward a my friend pressed the power button to turn the laptop off....i think at this moment sone read/write operation was being performed by read/write head of the HDD and when turned off read/write head remained there (did not come back to its default position = boot secor).normally when we turn laptop off the read write head moves back to boot sector so that it can start booting when we turn the device ON again ..but read/write head of my HDD is stuck where i turned the laptop off can i get the read/write head of HDD to come to its proper place ...????plz

Try System File Checker. It finds and replaces corrupted system files. You may need a copy of OS. At command prompt type sfc /scannow ENTER.

You can also use the Win 7 install disc:
Boot with a Win 7 disc, and choose Repair Your Computer. Then use Startup Repair option. Type bootrec /fixboot ENTER if end up at the command prompt. It does the same thing.

    It sounds like physical damage. The cost to fix is very expensive, more than a new computer, but try to connect as an external drive with an adapter.

SOURCE: the acer t120 computer frezes up and have to restart

If you are looking for a new hard drive, then I would highly suggest a Seagate Barracuda for size/speed verses cost.

1 Terrabyte version:

750 GB version:

160 GB Version:

One thing I would suggest is booting up and run a disk (error) check and select the option for scan and attempt recovery of bad sectors. If you need help on running that let me know what operating system you have and I can walk you through it.

If machine not booting it could be a bad cmos, hard drive, mo bo, peripheral, corrupted OS, bad power supply, bad memory,
Remove the hard drive and see if it posts and then gives you message that there no boot drive If that does not happen then machine is not even posting which means something is wrong with the cmos. - not a good thing.

Hi I bought a new ACER 5742 laptop yesterday. Its not recognising the CD's but showing the D:/ drive I have uninstalled the CD-ROM and restarted laptop, but doesn't help me.

AS you bought it yesterday, I wouldn't mess with it. Take it back and accept it again when the sales person demonstrates it working or demand a replacement.
