  • Windows Vista is installed on my recovery partition need help for this relocation.

    I have an acer extensa 5620, the labtob supplied with Windows Vista already installed. I ended up having to have my computer repaired because it became somehow infected by viruses a friend who I thought was well knowledged in computers, cleaned the virus or so I thought, and replaces Windows Vista with Windows XP I was not asking or giving permission for that to happen. Now, I came to know that Windows XP is not genuine a software which makes sense because I kept getting virus despite the fact that I have several systems antivirus on my computer and to make things worse, I'm sure I have a browser hijack. I tried to find a way, he made the switch to return to Vista because I liked it, but another friend told me I should stored it on my recovery partition. I don't know that much about computers if anyone can help me to find it and tell me step by step to correctly and safely to reinstall Windows Vista because I'm also fairly certain that bad software is whats allowing these viruses. Help, please!

    http://support.Acer.com/

    Contact Acer for the EXACT way to do.

    There is no Vista free download legal available.

    Contact your computer manufacturer and ask them to send a recovery disk/s Vista set.

    Normally, they do this for a cost of $ small.

    In addition, ask them if you have a recovery Partition on your computer/laptop to restore it to factory settings.

    See if a manual provided with the computer or go to the manufacturer's website, email or you can call for information on how to make a recovery.

    Normally, you have to press F10 or F11, Acer Alt + F10 at startup to start the recovery process...

    Another way I've seen on some models is press F8 and go to a list of startup options, and launch a recovery of standards of plant with it, by selecting the computer repair option

    See you soon.

  • I have 350 MB of photos on my photo library to iCloud. And used to synchronize the photos to my iPhone, I need help for this thank you

    I have an iPhone 4 32 gb

  • Is there a default value for the color management in PSE10? Beautiful photos from iPhoto, but blur with elements. I need help with this before as I consider that the upgrade to PSE13 and beyond.

    Is there a default value for the color management in PSE10? Beautiful photos from iPhoto, but blur with elements. I need help with this before as I consider that the upgrade to PSE13 and beyond.

    Printing which forms an angle seems ok, but one that is horizontally seems faded, incomplete.

    I was wondering if I saved a layer somewhere and set it as a default value.

    If you group the layers, you will be left with a single layer, thus spreading your concern.

    Suggest that you do the following:

    1. Make sure you have the latest drivers for your printers
    2. Reset the default preferences.

    Hold the Alt, Ctrl + Shift keys when you click the icon to open the items. When asked if you want to delete the settings file, say Yes.

    Items nearby and let regenerate the file.

  • Need help for optical safety circuit.

    I buy these parts and prototype with real components, but since I multisim, I thought it would be nice to create the circuit and maybe work through issues I can practically.

    I need a circuit that takes 120 VCA, generates 5 VDC and 1.5Vdc power of optical transmitter and receiver.  I actually use a data port because he has great range and is pretty cheap.  Rather than send the binary code well I just send a light stead that is broken or not broken through doors and windows in my house.  Then the receiver sees this as an entry and order a relay.

    I tried several voltage regulators that come with multisim, but I get an error of execution of my circuit.  Really I can't the 120 VAC to power levels necessary for the functioning of the optics.

    Otherwise I might want to run on a system 120Vdc with battery backup, so throw a 120Vdc up to 20 v DC switching power supply - but I have not found a SMP in the library which takes 120 as input and as output 20.

    Basic plan: 120VAC source-> transform to 24Vac-> Full bridge rectifier to ~ 20 v DC-> voltage capacitor filter on the input of two voltage regulators (1 to 5 VDC, 1 to 1.5Vdc) - then circuit since the two power supply of the transmitter and the receiver.

    I just need help for 5V and 1.5V, from there, I know that the real world circuit will work component tests already carried out.  Thanks for reading.

    I didn't Multism so I can't advise you on the compatible models. I ran the model on semiconductors with slight modifications of format on my SPICE simulator based on Berkeley Spice 3f5. I had to change the format of model resistance semiconductors appeal but has not changed any values.

    The output of your power supply circuit 3 (with 5 V, not the 1.5 V regulator regulator) was 4.99995 V.

    There are a few messages about changing templates published for compatibility Multisim woth. You can search those to see if there are any suggestions on what you'll need to fix in the model.

  • I need help for the upgrade of my current system.

    I need help for the upgrade of my current system.

    I have SBS 2008 with (Exch 2007, SQL 2005, Sharepoint, backupexec 2010 for sbs) licenses.

    I want to make the larger environment using the following:

    (1) apply Virtualization

    (2) apply to the failover process (clustering)

    "(3) the environment must support adding server terminal server, ERP server, exchange server, domain controller, backup manager.

    Storage 4) that supports Raid (1 and 5)

    UTM excellent 6) that supports (SSL VPN, VPN Global)

    suitable backup solution 7)

    (8) good antivirus for clients

    my questions:

    (1) can you provide me with a good design for this environment

    (2) should I choose what operating system:

    Microsoft datacenter or company

    I know datacenter provide us the unlimited VM but needs per processor license

    so if I have two Grouped servers I want to buy 4 licenses

    and just 4 VMs per company license... to say that we have two servers and maintain 8 vms so wat happened if 1 goes down... How can I migrate the 4 virtual machines on the server failed to another server group... ? should I buy enterprise license?

    (3) if I get the SAN storage for data... How can I save this storage... should I get another SAN?

    (4) how can I upgrade SBS stad single server (windows standrad) without losing the licenses as Exch 2007, SQL 2005, sharepoint.is it a must to buy an edition full std server or there is a way to upgrade (license wise, I mean)?

    (5) what about win2k8 license for VM:

    lets say we have physical that has windows license so that enough to have windows for VM or should I buy windows for VM licenses?

    (6) can I use backExec license for SBS with windows 2008 standard

    (7) who better to virtualization AMD or INTEL

    (8) hyper V or VMware?

    (9) what of Microsoft data protection Manager... is this good?

    (10) what virtual machine manager? What are the benefites keys

    Thanks in advance

    Go to the HP website, search for sp37394-XP sp3 Upgrade utility Microsoft for systems equipped with AMD processors.

    I had the same 0 x 80240036, 0x8024400a error, but realize my problem was really get manually downloaded sp3 and installed without continue loop crashing and not error messages.

  • Need help with this gallery of xml!

    I have build a gallery but its very simple... There are pictures of the xml file.

    I have attached all the zip files.

    I just want two things if anyone can help.

    first of all when I press the next button, he's going to the next image, but without effect. It just displays the following image... I want to incorporate the effect of dragging when the image is changed to another.

    and secondly, I want to use the AutoPlay feature.

    Once swf starts images came one by one with a vertical drop of a few seconds.

    Thanks in advance... I really need help with this..!

    For the look of sliding effect using the actionscript class Tween.  Allows you to create motion tweens using the code.  The example below will be tween property _x of the instance named anObject from 0 to 300 in 3 seconds...

    import classes before using

    Import mx.transitions.Tween;
    Import mx.transitions.easing.Regular;

    TW var = new Tween (anObject, "_x", Regular.easeIn, 0, 300, 3, true);

    To implement an enforcement function auto you need to import all the images first, in the order, then you will need to use form any controlled timer, such as setInterval (with clearInterval not to need) in order to have things turn on automatically by some part-time
