What causes the error message 'LSA shell has encountered an error' when you connect to the Internet?

LSA Shell ErrorsThis used to be caused almost exclusively by the sasser worm. You could simple download the scan and fix from McAfee.

There is now a more common worm that sasser that replaced. It may be causing the LSA Shell error. Your most common junk antivirus such as McAfee can detect and delete sasser. Most firewalls can stop sasser. This sounds more like the womourge worm. You can find and eliminate this with the tools from Symantec.

Here is more input:

  • Although these sites are great to find help and answers some people don't keep up with the information being released every momment of every day and it is difficult to keep up with the ever so progressive virus world. Please search out as many casses of this and read all info pertaining to it before fallowing one post. You could just end up in circles over and over again.
  • The solution is easy, somewhat. I take it when you receive the LSA Shell (Export Version) notice, a few moments later the System Shutdown Count appears? Not to worry. Just restart your computer, making sure that you are, in fact, disconnected from the internet. Then click Start, click Run, and in the white box type "cmd". A black box will appear, inside the black box, after your computer's administrater's name type "shutdown -I" (when typing this, don't forget the space between the hyphen and the word "Shutdown".) and press enter. The Shutdown Setting's window will appear. In the first box, type in your computer's name and click Add. Then in the box that reads: 20 seconds, type 9999. This will increase your time on the internet to about three hours!This will give you time to download Stinger, which can be found on the McAfee website. Stinger will find and repair this problem. Simple.
Solving the LSA Shell ErrorIt's simple and not that simple. Follow the services.msc technique:

1. click start -> Run

2. type "services.msc" (without the double quotes) and press Enter.

3. Double Click "Remote Procedure Call"

4. On the "Recovery" tab, change "Shutdown Computer" to "Restart the Service" for all Failure counts ie. 1st, 2nd and subsequent.

5. Press OK.

That should be the first step to preventing it. Then download any "Blaster Worm Removal Tool" from the net and scan your system for it. This shutdown is often caused by the msblast worm. That should fix your problem.

And if it continues, just do this everytime the shutdown count begins:

1. Select Start -> Run

2. type "shutdown -a" and press Enter

That's it. This solves everything. the countdown disappears.

Preventing the WormPrevention is better than cure.

If you had internet connection firewall (ICF) enabled, this wouldn't have happened. Worms use the LSA shell security flaw to get into the remote system. Enable the ICF by:

1) Right click connections icon in the Network Connections and select properties.

2) Go to advanced and tick ICF option.

This will evade viruses from getting into the system as it blocks all incoming connection requests.

Here is more input:

  • Go to Start > Run> type services.msc and search for RPC, double click on it and on the TAB's go to Recovery, all the failure notices that say "Restar the Computer", change them to "Restart the Service", apply it and then reboot your machine. Once you reboot, it'll give the error message again, but will stop once you press ok twice, restart your machine and it shall be removed.
  • Sometimes its not sasser or the msblast worm like for my case! So the thing is to go to run. type "services.msc" then go to the option "RCP" from there another window will pop up and click the recovery tab. change all three setting to "restart the service" and reset the comp. That should do it.
NoteIf none of these solutions worked for you, you can always restore Windows by using your original discs that came with the computer.

How do you install a hi-speed USB host controller on a Windows XP computer?

For the most part, the High Speed USB controller will be integrated right onto the motherboard of your system. You will sometimes run into this problem when upgrading to or installing a new version of XP, for sometimes it does not readily have the drivers available. What you have to do is to actually find out the motherboard that you have in your system, and download, or request the CD, that has the motherboard resources on it, in order to get Windows to install that particular controller. If you have a name brand computer, you should be able to contact the manufacturer to get the CD or download. However, if you have built the system, or someone else has built you the system, you will need the CD that came with the motherboard. Yes. If you have an empty PCI bus slot on the PC motherboard, you an install a PCI card which provides you 2 or 4 USB2.0 ports which are available at around $10. There are some combo cards which provide both USB and Firewire (1394 ports).

How do you find out what kind of graphics card you have?

If using Windows, open your Device Manager (Easiest way, click Start and type Device Manager). Expand Display Adapters. It should be listed there.

If it says "Generic" or so forth, right-click it, go to properties. Go to details tab. Drop down the list to the Hardware ID's, then use google to search for that hardware ID. That will tell you specifically what the card is (Vendor, model, etc.)

Will an 8x AGP video card work in a 4x AGP slot?

It will work, if it is compatible with the signalling voltage on the motherboard (1.5v for AGP 1x, 2x and 4x), but it will only work at up to the 4x that your motherboard is capable of. You may need to change your BIOS settings for AGP= 4x to obtain maximum performance from your motherboard and graphics card. AGP 8x cards run at 0.8v but some may permit 1.5v 4x compatibility.

Those folks experiencing problems with 8x cards in 4x slots might consider the possibility of power supply issues. It's not unusual to see newer cards requiring 300-350 watt power supplies with specific voltages requiring up to 18 amps. Many old Dells and others have only 250 watt supplies, and the new dual gizmo gazillion megahertz screamers take a lot more juice than the factory-supplied cards.

Some 8x cards are designed to be able to clock down to 4x, some are not. Many times it will say whether or not this is possible right on the box. In all respects the motherboard or 8x card should not be damaged by attempting this, the worst that will happen is it wont work.

How do you build a computer?

Buy a:
  • Case
  • Power Supply (Sometimes comes with case)
  • Motherboard
  • Processor/CPU
  • RAM/Memory
  • Hard Drive
  • CD/DVD Drive
  • Peripherals, such mouse, keyboard, and monitor.
  • An Operating System. Such as Windows or Linux.

Optional Components:

  • Video Card (For graphic intensive actions. Games and graphic design)
  • Sound Card (Higher quality sound. Home theaters and professional music editing)
  • Other peripherals, like earphones.

Before you buy, make sure all parts are compatible.

This is a simple summary of what to do, consult the manuals for each part for an in-depth guide.

  1. Place power supply into case.
  2. Put motherboard in place. Connect necessary cables.
  3. Install other components. Connect cables.
  4. Once all parts are done, close case and move onto peripherals.
  5. Plug peripherals in.
  6. Turn computer on.
  7. Install operating system.
  8. Install necessary drivers, usually found with product or on its website.
Setting up a computerwe need to know some additional info first:

what type of motherboard is it? (brand name, model #, mhz, etc.)

once a brand name is given for the motherboard and the model number, you can try searching for the manufacturer's website for downloading a manual or online instructions for installation. another important tip is to be careful of magnetic objects (screw drivers, etc.) near these parts AND static causing agents (including your hands, carpeting). these will ruin the parts by shorting them out.

The easiest way would be to buy a "BareBones" system. Depending how much you want spend will determine what you will get. Some of the systems will only require a harddrive and a operating system.

Compare and contrast hardware and software?

Hardware is any physical part of the computer necessary for it to operate ( basically anything inside the case)

Software is any programs or operating system installed on the computer, it is not essential for the computer to run but is necessary to complete certain tasks, it cannot be physically touched.

Hardware is essential for the computer to operate, without it nothing will work.

Hardware can be; Motherboards, Memory, Harddrives, CD Drives, Video Cards etc...

Software can be; Operating Systems e.g. Windows, Linux. or programs e.g. Microsoft Office, Adobe Reader, Windows Media Player. or Updates from the OS or Hardware Manufacturer

The Difference Between

What is the difference between a laptop and a notebook or netbook?

LaptopA mobile computer with a full-sized keyboard, flip-up monitor and space for built-in optical or floppy-disk storage drives.

A laptop is designed to sit on your lap and you can therefore expect it to be quite large and loaded down with features and power.

The standard laptop computer would have some ,if not all, of the following features:

1. 14" - 17" (widescreen) TFT screen.

2. Nvidia GeForce or ATI Radeon graphics subsystem.

3. Internal DVD-ROM or DVD-RW drive

4. Large full featured keyboard.

5. 3 hour (+/-) battery life.

6. Upgradeable.

7. Integrated modem, network, Bluetooth and Wi-Fi capabilities.

8. High quality integrate audio and speaker system.

9. Low power consumption, high performance Intel Centrino style processor.

Laptops are designed to be capable of replacing an entire desktop PC if necessary whilst still offering desktop performance in a mobile platform.

Notebook

A mobile computer with a full-sized keyboard and a flip-up monitor. It does not have space for built-in optical or floppy-disk drives, but instead provides communication ports so that an external drive can be connected. This allows a notebook to be much thinner than a laptop.

The notebook computer would have some ,if not all, of the following features:

1. Ultralight. Less weight is better.

2. 4 - 5 hour battery life.

3. No internal floppy drive.

4. Minimal graphics subsystem.

5. No internal DVD or CD system.

6. 12" - 14" TFT screen.

7. Low profile (thin).

8. Integrated modem and network connection.

9. Smallest possible keyboard that retains functionality.

10. Low power consumption Celeron/Centrino or Sempron style processor.

In essence a notebook computer is designed to provide mobile computing that won't break your back yet still offer all the power the mobile users requires for work and some leisure pursuits. This portability normally comes at a price. The level of miniaturisation involved comes at a cost and high end notebooks can prove to be quite expensive.

Notebooks offer reasonable power and extreme portability.

Note: Some Notebooks pretend to be tablets (see blow) as their screens are touch sensitive can fold back to cover their keypads.

Netbook or Mini PC

A mobile computer with a keyboard and screen smaller than full size (some are less than half the size). As with a notebook, it does not have space for built-in storage drives, but does provide ports for connecting an external drive.

Tablet

A mobile computer without a keyboard. It has a monitor that forms one side of the device. The monitor is touch sensitive and can present a virtual keyboard when input is required. The Tablet does not have ports to attach peripherals and has no disk storage.

Some of the most popular Tablets are developments of high end phones rather than 'smaller' PCs and many of the newer Tablets are being released with special 'new' operating systems which have no relation to MS Windows.This means that applications - 'Apps' for them can be downloaded from the Internet and most of the users data and processing is provided from the Internet 'cloud computing'.

What are the types of Optical Mark Reader?

OMR or optical mark reader integrates optical technology and electronics to do data inputs hundred times faster than manual entry methods and is extensively used in multiple choice examinations ,statistics,data input etc

The OMR types depends on

1.The accuracy needed

eg;In case of a question with four options out of which one is to be made black using pencil, if an option is more than 75% blackened ,modern OMRs will read it while first generation OMRs wont.

2.The cost

3.The security and anti tampering of data

The main parts include an OMR scanner and an OMR sheet printer and a data entry and transfer software.

There are mainly 3 types of OMRs.

1.OMRFD

2.OMRFBS

3.OMRFBD

Different compnaies like NANHAO,DEVOSOFT,AXIOME produce different versions of the above said version which cna range to upto 40 types of Optical Mark Readers

The difference among the three types lies in

1.The nature and dimensions of paper used for entry n scanning

2.The number of photoelectric sensors used and its efficiency (2,4)

3.The number of reading done for a single sheet for added accuracy( twice,thrice)

4.The size of the machine and software used.(windows based,linux based)

5.The barcode used(128,39,25)

6.Operating temperature and other parameters
