Since then, the system runs flawlessley.

  This morning, the machine began to behave differently - stop playing back badly, refused to start Device Manager, open Control Panel correctly etc.

  So, I reset the BIOS to boot from the CD-ROM, slapped XP SP3 in reinstalled, then upgraded to Win 7 again.

  Still have no idea what caused the problem, but it seems to be gone now - reinstalled the same applications, AV / programs anti-malware, games, etc and everything seems to go fine now.

  Info: Windows cannot verify the digital signature for this file.

  * So what the hell is happening? Sorry, but am getting very frustrated by that. I noticed that windows creates a file called windows.old. Avoid the old windows, it's an empty hard disk, and it was an installation of full version. NOT an upgrade. As to why my product key does not work... not even me angry by publishing what I've seen elsewhere in these forums. I DO not pay another $200 for a different product key. This one should work. I just opened this "thing" to do the installation. So if this key was stolen, it was stolen that microsoft has packaged discs.

  Can I safely delete this file called windows.old (assuming that I can always go back to windows 7)? Do you think this has nothing to do with the problem? Or should I do what ppl do upgrades mean that they have to do... Reinstall win 7?
  * He let me use F8 for advanced options to disable the driver signature.

  Thank you! Got the product key problem is resolved. I saw on another post, you stated

  Now that address my other question as much as me have allowed difficulty delivers windows boot is seen? I see that windows 7 is a file boot.ini as previous versions of windows. I would like to see the "command-line" some win 7 has instead of boot.ini file uses. I suspect something may be there that causes the driver signature error... and tried the 'bootrec' methods above doesn't solve anything for me.

  Thanks a lot for your help in this matter. (Once I get the verify signature driver disabled it goes straight in win 7 and win 7 works fine.) It just will not be disabled whenever I start my pc. I always have to fight to get the window that gives me the ability to disable.)

  We downloaded an automatic update of our HP Pavilion laptop running Windows 7.  This disabled somehow the wireless network adapter.  Readings of the error; "Windows cannot verify the digital signature for the drivers required for this device.  A recent hardware or software change might be installed a file that is signed incorrectly or damaged, or that might be malicious from an unknown source.

  Well, the first thing I did was put in the installation CD and reboot to try the thing "repair your computer".  Charge, said he found a problem, said he has fixed the problem and restarted.  But it always hangs on the same screen of the error.

• Satellite A200-1YO - problems installing Windows XP Home edition

  Hi guys,.

  First of all I'm new here so Hello to everyone here and I hope you can help me with my problems of software.

  I recently bought a laptop model Toshiba Satellite A200-1YO provided with windows vista (which must be frank, pants and IMO too demanding for the machine) and I have a problem with vista, because some of its features do not seem to work, for example, I'm having a lot of trouble getting some of the webpages to open now, they simply hang out.

  now, I didn't install windows xp but I don't have an external floppy drive. This is not a problem but because I can use Nlite to integrate the drivers in a new ISO of Windows XP.

  The problem is that I have 4 sets of drivers: ICH7M_32bit, ICH7M_64bit, ICH8M_32bit and ICH8M_64bit. As I install Windows XP 32-bit while I'm more or less some that I have not need 64-bit drivers but when I install Windows XP by using the modified version of windows xp slipstreamed, what I get at startup is a BSD error telling me that something has crashed on my hard drive , however I can't say which crashed as the screen disappears after 15 seconds if that so I guess there is something wrong with the drivers I use (though I must admit that I'm not sure the drivers 32-bit to use)

  advice and assistance regarding being able to install windows xp would be welcome, as I said above, however, I can only use Nlite since I do not have a usb floppy drive.

  Satellite A200-1YO has a chip with the ICH8M southbridge Intel GM965.

  So you need the driver for SATA ICH8M_32bit.

• Windows cannot verify the digital signature - Microsoft Surface, Windows RT

  Hi putte32,

  To be honest I never received this error before but it sounds like that recovery creator disc doesn t work properly... You should try a HDD recovery to restore the factory settings. Maybe you are able to create the recovery disk.

  Otherwise, I would contact an authorized service provider. If you can t create the recovery disk, the guy should be able to help you to complete this procedure.

• On Satellite L505 keyboard problem

  Hello

  I just bought a Toshiba Satellite L505 and for some a touch of reason will not work it s the last letter of the alphabet.
  I can t he type for obvious reasons. I'm staying in Saudi Arabia and using a keyboard with English and Arabic letters. I'm English, so don t requires the Arabic alphabet.

  Any ideas or I would return the laptop?

  Hoping for an answer. Thanks Vic

  Hello

  I don t think that you must return the computer laptop everything. Maybe it s just a bad setting in Windows then what keyboard input language you have in Windows?
  Run you to the factory settings or other OS?

  If a key or keys more n t work you need to swap the keyboard. There is no unique key, need to replace the entire keyboard, but it shouldn't t so be so expensive. Just ask an authorized service provider to get a new, and they can exchange it too. :)
