Hi karthik17v...

You have a couple of things you can do to speed up your system
1...Clean the disk...Start>All Programs>Accessories>System Tools>Disk Cleanup..Check the boxes/programs you want to clean-up
2...Defrag the HD...Start>All Programs>Accessories>System Tools>Disk Defragment
3...Add as much memory as the computer will allow.
5. Install and use a ram memory saver program...it will clean and allow the reuse of your Ram...
You can download a free ram optimizer from this webpage: http://download.cnet.com/Free-Ram-Optimizer-XP/3000-2086_4-10238479.html?tag=mncol;1
6...Check your computer for virus's,worms,trojans.
You can do this for FREE.
It may take a while to scan and clean your computer, depending on your Hard Drive size.
If the Microsoft Safety Scanner does not remove all the virus/worms/trojans...you will be given an opportunity to talk to a Microsoft Professional (via a chat window) and he/she will take over your computer (with your permission) and finish removing the virus,trojan,worm for you for FREE...
Go to the following webpage and download,install and run Microsoft Safety Scanner:

Tip

Different types of Virus and their effect's.


Different Types of Computer Viruses There are Different Types of Computer Viruses could be classified in (origin, techniques, types of files they infect, where they hide, the kind of damage they cause, the type of operating system or platform they attack) etc. Let us have a look at them…

Computer Virus is a kind of malicious software written intentionally to enter a computer without the user’s permission or knowledge, with an ability to replicate itself, thus continuing to spread. Some viruses do little but replicate others can cause severe harm or adversely effect program and performance of the system. A virus should never be assumed harmless and left on a system. Most common types of viruses are mentioned below:

fb7fa0a.jpg

Resident Viruses
This type of virus is a permanent which dwells in the RAM memory. From there it can overcome and interrupt all of the operations executed by the system: corrupting files and programs that are opened, closed, copied, renamed etc.

Examples include: Randex, CMJ, Meve, and MrKlunky.

Direct Action Viruses
The main purpose of this virus is to replicate and take action when it is executed. When a specific condition is met, the virus will go into action and infect files in the directory or folder that it is in and in directories that are specified in the AUTOEXEC.BAT file PATH. This batch file is always located in the root directory of the hard disk and carries out certain operations when the computer is booted.

Overwrite Viruses
Virus of this kind is characterized by the fact that it deletes the information contained in the files that it infects, rendering them partially or totally useless once they have been infected.

The only way to clean a file infected by an overwrite virus is to delete the file completely, thus losing the original content.

Examples of this virus include: Way, Trj.Reboot, Trivial.88.D.

Boot Virus
This type of virus affects the boot sector of a floppy or hard disk. This is a crucial part of a disk, in which information on the disk itself is stored together with a program that makes it possible to boot (start) the computer from the disk.

The best way of avoiding boot viruses is to ensure that floppy disks are write-protected and never start your computer with an unknown floppy disk in the disk drive.

Examples of boot viruses include: Polyboot.B, AntiEXE.

Macro Virus
Macro viruses infect files that are created using certain applications or programs that contain macros. These mini-programs make it possible to automate series of operations so that they are performed as a single action, thereby saving the user from having to carry them out one by one.

Examples of macro viruses: Relax, Melissa.A, Bablas, O97M/Y2K.

Directory Virus
Directory viruses change the paths that indicate the location of a file. By executing a program (file with the extension .EXE or .COM) which has been infected by a virus, you are unknowingly running the virus program, while the original file and program have been previously moved by the virus.

Once infected it becomes impossible to locate the original files.

Polymorphic Virus
Polymorphic viruses encrypt or encode themselves in a different way (using different algorithms and encryption keys) every time they infect a system.

This makes it impossible for anti-viruses to find them using string or signature searches (because they are different in each encryption) and also enables them to create a large number of copies of themselves.

Examples include: Elkern, Marburg, Satan Bug, and Tuareg.

File Infectors
This type of virus infects programs or executable files (files with an .EXE or .COM extension). When one of these programs is run, directly or indirectly, the virus is activated, producing the damaging effects it is programmed to carry out. The majority of existing viruses belong to this category, and can be classified depending on the actions that they carry out.

Companion Viruses
Companion viruses can be considered file infector viruses like resident or direct action types. They are known as companion viruses because once they get into the system they "accompany" the other files that already exist. In other words, in order to carry out their infection routines, companion viruses can wait in memory until a program is run (resident viruses) or act immediately by making copies of themselves (direct action viruses).

Some examples include: Stator, Asimov.1539, and Terrax.1069

FAT Virus
The file allocation table or FAT is the part of a disk used to connect information and is a vital part of the normal functioning of the computer.
This type of virus attack can be especially dangerous, by preventing access to certain sections of the disk where important files are stored. Damage caused can result in information losses from individual files or even entire directories.

Worms
A worm is a program very similar to a virus; it has the ability to self-replicate, and can lead to negative effects on your system and most importantly they are detected and eliminated by antiviruses.

Examples of worms include: PSWBugbear.B, Lovgate.F, Trile.C, Sobig.D, Mapson.

Trojans or Trojan Horses
Another unsavory breed of malicious code are Trojans or Trojan horses, which unlike viruses do not reproduce by infecting other files, nor do they self-replicate like worms.

Logic Bombs
They are not considered viruses because they do not replicate. They are not even programs in their own right but rather camouflaged segments of other programs.

Their objective is to destroy data on the computer once certain conditions have been met. Logic bombs go undetected until launched, and the results can be destructive.

I have worms and trojans so how do i reboot


I do not understand your question. If you have worms and trojans, rebooting is not going to fix them. You need to run anti-virus / anti-spyware / anti-malware software to fix these problems. There are numerous free solutions AVG and Comodo are two I recommend to my customers. AVG is less comprehensive but requires less user intervention to install and use. Comodo provides comprehensive protection but includes a firewall you need to setup and will ask lots of questions during computer use.

How do I fix the dcom server launcher, the computer keeps shutting down after it's been on for about five minutes?


Click Here to Download this program (its free). Install it. Update it. Run a FULL scan of your computer (took about 30 minutes and the viruses didn't pop up until the very end of the scan). Delete ALL of them (note: you have to reboot to delete the ones in windows system 32) There will be a list of about 5-10 infections they should be similar to:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\tdssdata (Trojan.Agent)

HKEY_LOCAL_MACHINE\SOFTWARE\tdss (Trojan.Agent)

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\Tcpip\Parameters\NameServer (Trojan.DNSChanger)

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\T cpip\Parameters\NameServer (Trojan.DNSChanger)

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet003\Services\T cpip\Parameters\NameServer (Trojan.DNSChanger)

C:\WINDOWS\system32\tdssadw.dll (Trojan.Agent)

C:\WINDOWS\system32\tdssl.dll (Trojan.Agent)

C:\WINDOWS\system32\tdssserf.dll (Trojan.Agent)

C:\WINDOWS\system32\tdssmain.dll (Trojan.Agent)

C:\WINDOWS\system32\tdssinit.dll (Trojan.Agent)

C:\WINDOWS\system32\tdsslog.dll (Trojan.Agent)

C:\WINDOWS\system32\tdssservers.dat (Trojan.Agent)

C:\WINDOWS\system32\drivers\tdssserv.sys (Trojan.Agent)

AMI BIOS Beep Codes

 1 Short Beep One beep is good! Everything is ok, that is if you see things on the screen. If you don't see anything, check your monitor and video card first. Is everything connected? If they seem fine, your motherboard has some bad chips on it. First reset the SIMM's and reboot. If it does the same thing, one of the memory chips on the motherboard are bad, and you most likely need to get another motherboard since these chips are soldered on. 
2 Short Beeps Your computer has memory problems. First check video. If video is working, you'll see an error message. If not, you have a parity error in your first 64K of memory. First check your SIMM's. Reseat them and reboot. If this doesn't do it, the memory chips may be bad. You can try switching the first and second banks memory chips. First banks are the memory banks that your CPU finds its first 64K of base memory in. You'll need to consult your manual to see which bank is first. If all your memory tests good, you probably need to buy another motherboard. 
3 Short Beeps Basically the same thing as 2 beeps. Follow that diagnosis above. 
4 Short Beeps Basically the same thing as 2 beeps. Follow that diagnosis above. It could also be a bad timer 
5 Short Beeps Your motherboard is complaining. Try reseating the memory and rebooting. If that doesn't help, you should consider another motherboard. You could probably get away with just replacing the CPU, but that's not too cost-effective. Its just time to upgrade! 
6 Short Beeps The chip on your motherboard that controls your keyboard (A20 gate) isn't working. First try another keyboard. If it doesn't help, reseat the chip that controls the keyboard, if it isn't soldered in. If it still beeps, replace the chip if possible. Replace the motherboard if it is soldered in. 
7 Short Beeps Your CPU broke overnight. Its no good. Either replace the CPU, or buy another motherboard. 
8 Short Beeps Your video card isn't working. Make sure it is seated well in the bus. If it still beeps, either the whole card is bad or the memory on it is. Best bet is to install another video card. 
9 Short Beeps Your BIOS is bad. Reseat or Replace the BIOS. 
10 Short Beeps Your problem lies deep inside the CMOS. All chips associated with the CMOS will likely have to be replaced. Your best bet is to get a new motherboard. 
11 Short Beeps Your problem is in the Cache Memory chips on the motherboard. Reseat or Replace these chips.
1 Long, 3 Short Beeps You've probably just added memory to the motherboard since this is a conventional or extended memory failure. Generally this is caused by a memory chip that is not seated properly. Reseat the memory chips.
1 Long, 8 Short Beeps Display / retrace test failed. Reseat the video card.
