Why would your computer automatically restart after being turned off?
All Windows versions have the same function. From the Start button, select menu/programs/accessories/system tools/system information, then click on the tools menu and select system configuration utility.
When the program opens, you'll see an advanced button on the bottom right corner. Press it.
Make sure you have disabled fast shutdown (CHECKED). Press OK/OK. If it prompts for restart, don't do it, you don't need to. Press cancel on that screen and then shutdown like you would normally.
AnswerI have found I think the answer to that question, although I haven't had the time to test it since it is on a friends computer using xp pro. but you can if you like. go to the bios and check your modem if you are on a phone line and disable the auto start feature...You may find it only restarts when a call comes in... AnswerThe bios settings turn the computer on automatically. I actually have mine set to turn on automatically in the morning before I get out of bed so it's already on when I get up.Watch what you see on your screen as you boot up the computer and do whatever it tells you to do to boot up in bios (typically by hitting the F2 or Del key). Once in bios, go to the power section. In the power setting you should see something pertaining to the modem. If you do NOT want it to power up automatically, choose the Disable option.
If you DO want to power it up automatically, it will also ask for a time (day of month, hour, minute). If you set the day as 1, for example, it will power up on the 1st of the month at the time that is set. If you set the day of the month to zero (0), it will power up every day at that time.
AnswerTry turning off the hibernation feature that can be found through control panel->display->screensaver tab->power->hibernate and then turn off the hibernation feature AnswerOpen your registry: and find the key PowerdownAfterShutdown and set it to "1" to power off the computer at shutdown, or "0" to reboot. Here is the path: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\Winlogon If you don find it, create it(REG_SZ (String Value)) restart windows AnswerAll are very good answers. How are you shutting down your computer? Do you go to start shut down and then press ok or do you hit alt + f4? First I would check to see if my PC was set on restart in the shutdown window just before you click ok. If it is change it to say shutdown. Then I would try some of the other answers but they take a good knowledge about computers if you mess up. Hope it helps. AnswerFirst go to your start menu and then right click my computer and click properties.click on advanced tab and then under startup and recovery click on settings..
then under system failure uncheck the automatically restart....
AnswerLook in your bios for a Wake on Lan option also.What is the purpose of the northbridge?
It depends on the type of CPU used. Originally, the northbridge chip served as a memory controller, AGP bus controller, and system bus. It interfaced with the CPU, the RAM, and the southbridge chip. The southbridge connected to about everything else. But most of the northbridge functions are now done by the CPU in many computers. The memory controller and sometimes even graphics are in the CPU these days.

Answer:
Disk Cleanup (cleanmgr.exe) is a computer maintenance utility included in Microsoft Windows designed to free up disk space on computer users' hard drive. The cleanup process firstly involves searching and analyzing the hard drive for files that are no longer of any use. It then proceeds to remove the unnecessary files, freeing up disk space on the hard drive. There are a number of different file categories that Disk Cleanup targets when performing the initial disk analysis:
Compression of old files
Temporary Internet files
Temporary Windows file
Downloaded Program files
Recycle Bin
Removal of unused applications or optional Windows components
Setup Log files
Offline files

What is the function of instruction register?
The Instruction Register (IR) stores the instruction currently being executed. In simple processors each instruction to be executed is loaded into the instruction register which holds it while it is decoded, prepared and ultimately executed.
How do you restore deleted files from hard drive?
Use Recycle bin; if you already emptied that or its not there, then there is no other way.
-----------------------------------------
If you haven't rebooted yet THERE IS A WAY, you can use a free third party software like "undelete".
-----------------------------------------
Rebooting has nothing to do with it. The more you use the drive after deleting the file, the more likely the file will not be recoverable. When you 'delete' a file the space just gets marked as 'available' for being overwritten. The file actually stays out there until another file gets written over the top of it. If you google for 'undelete' you will find plenty of programs that are able to attempt a recovery. I'm not going to promote a specific one here.
I have managed to recover files for people. Just be warned that the file might only be partially recoverable (like the top half of a jpeg photo with the rest corrupted) and that the partially recovered file might not even be readable/viewable. Also these recovery programs should be installed to a separate drive and the files you are trying to recover should also get saved to a different drive. That way you won't ruin the file you are trying to recover.
Why your computer shows high memory usage?

What was the persons name who invented computers?
ENIAC was conceived and designed by John Mauchly and J. Presper Eckert of the University of Pennsylvania.
The first computer like ours first was invented by Charles Babbage.
Approximately 35,000 B.C
A small piece of the fibula of a baboon, marked with 29 clearly defined notches, may rank as the oldest mathematical artefact known. Discovered in the early seventies during an excavation of the Border Cave in the Lebombo Mountains between South Africa and Swaziland, the bone has been dated to approximately 35,000 B.C. In a description of the bone, Peter Beaumont, an archaeologist who has done extensive work on Border Cave, has noted that the 7.7 cm long bone resembles calendar sticks still in use today by Bushmen clans in Namibia.

The abacus was probably invented in the Middle East. In the West, from early Roman times, users calculated with a "table abacus" that involved manipulating coin-like discs, or "jetons," on lines drawn on a table or cloth. The table abacus remained in use in parts of Britain and northern Europe until the late 1600s.
In the East, several Asian civilizations used a technique similar to the table abacus until about 1200 AD when the more familiar wire and bead abacus was created in China. As late as 1946, the US Army newspaper Stars and Stripes sponsored a contest pitting a Japanese abacus against an electric calculator. The abacus won.

1860
Charles Babbage developed the "Difference Engine," a mechanical device that could perform error-free calculation of polynomial functions. He completed only a small model before the British government withdrew funding, forcing him to abandon the project. Soon after, Swedish scientists Georg and Edvard Scheutz would complete a working version.

Theoretically, you can use a USB port to connect up to 127 devices. To do so, you would need to use hubs. The problem with using hubs is that they count as devices. Thus if a hub has 4 sockets, it counts as 5 of the 127 devices.

Your laptop screen doesnt work what should you do?
There are some likely causes:
The screen illumination may have failed. If you can see a very faint image on the screen, that is the likely problem.
It may be the video driver chips that have failed. Try to connect an external monitor to the VGA port. You will need to enable the external port using one of the function keys (take a look in your manual to confirm how to do this). If the external screen doesn't work, it is possible that the driver chips have failed.
There are many companies that can assist with diagnosis and parts to help with a repair.
