How can I Troubleshoot USB PORT of my laptop (Acer Aspire E1-421)

Since I installed my Windows 7 Ultimate 36 bit fresh after a big Crash and BSOD and frost took place

My laptop has often experience problems...

It has been 2 months since my OS re-installing

I don't know why this is happening...

My USB Ports, one is USB 2 (blue) and the other 2 is USB 1 (Silver)

Cannot read any USB key, connectors or no matter what USB devices connected

Well maybe im that I'm wrong about the word 'impossible to read.

because when I PLUG it, it still appears on device and printers,

and Device Manager...

Yes, it was red by Ports but is not recognizing that I think...

One thing I think is one of the problem is...

As you can see I can not this devices/drivers because when I do it shows...

Ive also tried to use the Scan for hardware changes, but that's what always happens...

And it's always...

I appreciate really all help and step by step answers someone will answer.

Thank you very much...

Almost certainly yes a reload will sort it but next time avoid the utility 'finder pilot', they are a pain because too often they go wrong and I speak from personal experience.

Stick with drivers Acer, there is no chipset graphics drivers followed by Audio 1 and restart, then next LAN. Let the system do its updates and check the Device Manager to each step.

The SMBus is a little strange because it's undoubtedly part of the chipset, but Acer don't list any as being necessary.

  • How can I find the hard drive in my Acer Aspire 10.1 switch keyboard docking station?

    My Acer Aspire 10.1 switch was sold with an additional 500 GB HDD in the keyboard. But the drive only extra hard (except C :) I can find in Explorer's "recovery (D :) ", but this is ony 32 GB, but it goes away when I remove the keyboard, so it is in the keyboard. At the start of the computer there is certainly a hard drive of sound from the keyboard, so there is something in there. OS is Win 8.1.

    the 500 GB HARD drive is on the keyboard, so if you disconnect Switch10, you lose the remote storage.

    You can check it in disk management:

    Logo of the Windows key + x

    Click on disk management

    It will be all avilable storage the list, in order to check if the HDD 500 GB is there and if it is listed as unallocated space.

  • How can I change it to English version my acer aspire one D255 window7 because it is in the language and Japanese characters

    I don't know how to change my aspire D255 in English language.it is in japanese.please help me... Thank you

    Looks like you bought it with the Japanese and want to just English from top to bottom.  Probably the best thing to do is call Acer Support and see if you can pay for the DVD of restoration.  This will not only get you on English, but you'll have the right support for future use.  I hope less than a hundred dollars.

    If you want to be darring you could wipe the computer and install Windows 7 English yourself.  To do this, you must ensure that there is a COA sticker and the key on the bottom of the computer.  25 letters in five groups.  Second, you must borrow a DVD of Win7 which corresponds to the version of Windows 7 on this sticker.  Home Premium, ultimate, whatever.  Then boot from the DVD, format the computer and install Win7 English.  When asked to activate, you need to use the 25-digit key.  If that sounds scary, it take to Best Buy or store and have them do you like 50 dollars.

    or backup your data and reinstall

    Contact the computer manufacturer and ask them to send vista recovery discs

    they do it for a nominal cost of $

    also ask them if you have a recovery partition on your hard drive to get back to the way you bought

    you would normally press F10 or F11 or Alt + F10, 0 at startup to start the recovery process according to the manufacturer

    Ask them of the exact key sequence

    Save all data, because it will be lost, do the above
