Hi, I'm having a problem with my laptop. I bought my laptop online, a year ago, and I got a virus. Then, I had my computer reset and I need a code for Windows Vista from the bottom of my laptop. After looking through records and information, we found that he had no number. He worked initially but then recently he was asked for a product key or something of the sort code. I was using my laptop but I cannot customise my background etc.
Can you help me?
Thank you very much
The code is located on a label and is a 25-digit alpha-numeric (and very hard to read) code separated into 5 groups of 5 numbers separated by dashes. If you can't find it on the bottom of your laptop, open the battery housing and remove the battery and look there - I know of cases where this is where it was placed.
If you can't find the product key, your only choice is to contact the manufacturer and see if they can help. Sometimes the relocations made with recovery disks don't need to be activated (depends on the manufacturer and their recovery process must ask them and confirm before you spend money on the recovery discs). A valid product key is required for activation if activation is required - there is no way around this problem. And in case you are considering on it, you can't switch from one product not enabled - you need to do a clean and complete installation (update disc will not work).
I hope this helps and that the manufacturer can help you.
Good luck!

When I entered the product key at the bottom of my laptop computer to activate the Windows desktop is said that it is incorrect.

The product key on the bottom of your laptop isn't for Windows (operating system), Office (Word, Excel, etc.). You should have a sticker separated provided with Office.

Hello
USB devices remove all you can - restart the computer - is still there, the error? If it isn't
It is related to one of the add-in devices that you removed. If she is still there, then, the question is
either a device internal who can not remove or physically with the USB bus itself.
If it was not there, add devices at a time until it is displayed - keep in mind that it is
possible that there are two (or more) devices in conflict over the issue. Once you
identified the check of the aircraft with the help of the manufacturer.1. to find the control panel - device - device - right-click on it - uninstall - Manager then
Restart the computer to see if it clears.2. same place - double click on the device - driver tab - driver update - to see if that helps.
3. check with the support of system manufacturer (manufacturer of motherboard for customized systems), their
online documentation and drivers, diagnostics and ask questions in their forums on all known
questions. Update the Bios and chipset or other USB drivers.=====================================

Windows Update has appeared today when we started one of our machines, informing us that there are some installed updates. After reviewing the updates, we clicked on the "Install now" button, and immediately, it failed with the above error code.
I tried to run regedit a reason unrelated, and it came with a dialog box error with "Windows cannot verify the digital signature for this file. A recent hardware or software change might be installed a file that is signed incorrectly or damaged or maybe it's a malicious software from an unknown source. »
After researching here and elsewhere on google and did not find anything suitable, put us in the Win7 disk, recovery tools and tried to go back to a previous system restore point (3 days).
The restoration went well, restarted, but the problem persists.
Then, we just tried to install anti-malware software, but when trying to run the installer, we get a different error message indicating 'ShellExecuteEx failed; Code 577 "and then the same message on the verification of the digital signature.
The computer is running fine all yesterday and has worked very well since just after the new year when he has been upgraded to Windows 7. No material changes have been made, and no software changes were made by users in the course of last week.
The computer is an AMD Athlon II X 4 with 4 GB of RAM on a motherboard Asus M4A78-EM, linking a 64 GB SSD, with a 250 GB drive SATA data/programs. GPU is a Nvidia 260, and it has a CD and DVD player as well. It is connected to our router using the gigabit ethernet interface motherboards.
It was under windows 32 - bit XP SP3 up just after the new year. When we put in place the new SSD to replace a hard drive older than we have did a new install of XP (slipstreamed with SP3) and then used the upgrade 32-bit W7 Home premium DVD version to upgrade the system. Since then, the system runs flawlessley.
On the machine is MS office XP, Firefox 3.6.3, AVG 8.5 and a few games such as the Turbine DDO.
The main user account used to try to solve these problems and to run Windows Update and try installing programs is a member of the Administrators group.
Firefox works fine, serve, and he plays the games installed very well also. AVG reports to date, with no problems and has detected no threat.
However, try to view the registry with regedit, or start Viewer event or compmgmt.msc that all do appear the message "cannot verify the digital signature.
***************************************************
Can anyone offer an opinion on what might be wrong with this facility please, and how we could do to solve?
Cannot run chkdsk/scandisk as he bought the message "cannot verify the digital signature" etc etc.
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.

Help, please! Windows cannot load the device driver for this hardware (HL-DT-ST DVDRAM GH40F SCSI CdRom Device) because the driver may be corrupted or missing. (Code 39)
Hello
Code 39 means that the driver is corrupted or missing.
Please make all below even if you have done some before as it is often the set of operations which solves
the question.Try this - Panel - Device Manager - CD/DVD - double-click on the device - driver tab - click
Update the drivers (this will probably do nothing) - then RIGHT click the drive - UNINSTALL - REBOOT
This will refresh the default driver stack. Even if the reader does not appear to continue below.
Then, work your way through these - don't forget the drive might be bad, could be a loose cable or
slight corrosion on the contacts (usually for a laptop) and other issues.Your CD or DVD drive is missing or is not recognized by Windows or other programs

Also check with your system manufacturer to see if there are any updated drivers for your DVD. Or even if it
are you can reinstall the 'old'. Many use Windows default drivers however some special aura
ones. Also check the website of the manufacturer of the car.Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.

This device does not work properly because Windows cannot load the drivers required for this device. (Code 31) in the graphics AMD - 8151 HyperTransport (MC) AGP3.0 Tunnel, what do I do to fix this help please.
Jake
Hey Jake,
Follow these methods.
Method 1: Follow these steps:
(a) restart your computer if you have not already done so. There is always the possibility that the error Code 31 that you see was caused by a temporary problem with Device Manager. If so, a simple reboot can solve the Code 31.
(b) have you install a device or a change in the Device Manager, just as the Code 31 error appeared? If so, it is very possible that the modification caused the Code 31 error.
(c) cancel the change if you can restart the computer and then check again the error Code 31. Depending on the changes, some solutions may include:
Remove or reconfigure newly installed unit.
Restore a version prior to updating the driver.
Use system restore to undo the Device Manager recent related changes.
http://Windows.Microsoft.com/en-us/Windows-Vista/system-restore-frequently-asked-questions
(d) to remove the registry values filters upper and lower. A common cause of errors in Code 31 is the corruption of two registry values in the class of the CD-ROM/DVD-ROM drive registry key.
Note: This section, method, or task contains steps that tell you how to modify the registry. However, serious problems can occur if you modify the registry incorrectly. Therefore, make sure that you proceed with caution. For added protection, back up the registry before you edit it. Then you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following link. http://Windows.Microsoft.com/en-us/Windows-Vista/back-up-the-registry
Method 2: Update the latest graphic drivers.
