Windows XP Installation
Windows Vista ReadyBoost
Windows ReadyBoost improves system memory and boosts performance.Adding system memory (typically referred to as RAM) is often the best way to improve a PC's performance, since more memory means more applications are ready to run without accessing the hard drive. However, upgrading memory can be difficult and costly, and some machines have limited memory expansion capabilities, making it impossible to add RAM.Windows Vista introduces Windows ReadyBoost, a new concept in adding memory to a system. You can use non-volatile flash memory, such as that on a universal serial bus (USB) flash drive, to improve performance without having to add additional memory "under the hood."The flash memory device serves as an additional memory cache—that is, memory that the computer can access much more quickly than it can access data on the hard drive. Windows ReadyBoost relies on the intelligent memory management of Windows SuperFetch and can significantly improve system responsiveness.It's easy to use Windows ReadyBoost. When a removable memory device such as a USB flash drive or a secure digital (SD) memory card is first inserted into a port, Windows Vista checks to see if its performance is fast enough to work with Windows ReadyBoost. If so, you are asked if you want to use this device to speed up system performance. You can choose to allocate part of a USB drive's memory to speed up performance and use the remainder to store files.The capacity of the removable media must be at least 256 MBDevices larger than 4GB will have only 4GB used for ReadyBoostThe device should have an access time of 1ms or lessThe device must be capable of 2.5 MB/s read speeds for 4 kB random reads spread uniformly across the entire device and 1.75 MB/s write speeds for 512 kB random writes spread uniformly across the deviceThe device must have at least 235 MB of free spaceNTFS and FAT32 are supportedThe initial release of ReadyBoost supports only ONE device
How does the Ravmon Virus affects your PC?
When you Open any drive in My Computer by right clicking, the Context menu will have a chinese like language & when you click on this language on context menu, the drive will not open but the Open With dialouge will ask you to “Choose the program you want to use to open this file:”. Also by double clicking any drive same thing happens.Context Menu and OpenWith Dialogue will look like this. The Ravmon virus does also corrupt your Folder Options. So when you open Folder Options and try to check “Show hidden files and folders” and click ok. My Computer will not show hidden files, also “Hide protected operating system files (Recommended)” option will not be working.Folder Options Dailogue
Error launching Task Manager, Registry Editor and Command prompt which is also solved by this tool
How Does the Ravmon Virus Spread?Ravmon Virus mostly spreads from USB Flash drives. So to prevent this virus from breaking into your pc you must start an Anti-Virus before plugining a Flash drive into your pc.For Removing Ravmon virus and its effects I have created a tool. Just download it, run it and Restart your computer.
Download Ravmon Removal.exe http://www.technize.com/?dl_id=6
Remove RavMon.exe virus without any anti-virus
you will have to follow just few simple steps.
check if ur infected
stop currently running virus

there will be a program in processes named “SVCHOST.EXE” there will be few svchost in small case but check one in capital letters, if you see more than one “SVCHOST.EXE” (all caps one) end the one with your username infront of it instead of LOCAL SERVICE, NETWORK SERVICE or SYSTEM.by pressing end process
3. to delete the virus files you need to show system protected files.
for this goto

Access drive by typing drive letter and delete files from that drive
Remember you double click the curropted drive you get infected else ur safe
How To Repair Windows ???
Click start > run > type in "sfc /scannow" (without the quotes) then OK
This does a System File Check. If the scan finds any files that are corrupt or missing, it will prompt you to insert your XP CD. **Note the space in between sfc and /scannow.**
The scan can take quite a while so be patient. When the scan is finished, you'll be prompted to reboot and hopefully the problem will be solved. If the problem still exists, I'd try a Repair Install.
1. With the XP CD installed, turn on your computer.
2. You should see a prompt to "Press Any Key to Boot From CD"
(If you don't see this prompt you might have to modify your BIOS so the computer boots from CD.)
3. After pressing any key (usually the space bar) Info is loaded from the CD onto the hard drive. Eventually you will see a "Welcome To Setup" screen with three choices. Press enter to choose setting up Windows XP. DO NOT PRESS *R* TO SELECT "REPAIRING XP WITH RECOVERY CONSOLE"!!!
4. Press F8 to accept the licensing agreement. You should now see a screen that says, "If one of the following Windows XP installations is damaged, Setup can try to repair it." You should also see the drive (usually C:) on which the XP is installed.
5. With the drive selected (highlighted), now press "R" to begin the repair.
6. Again, be patient. The repair could take a while. Eventually, you will see a prompt to "Press Any Key". DO NOT PRESS ANY KEYS AT THIS POINT!!!! If you press any key, the computer will reboot from the CD. You don't want that. Let the computer reboot from the hard drive. Just give it a minute or two and it will reboot by itself.
7. Depending on how extensive the damage is, the repair process could end, or more than likely, it will continue and prompt you along the way.
8. Once again, you will get a prompt to "press any key" and once again, DO NOT PRESS ANY KEY. When the computer reboots this final time, you should be at the desktop ready to go.
9. By doing a repair, you will need to go to Windows Update site to reinstall any patches, hotfixes, critical updates, etc. that came out AFTER your CD was manufactured.
Hope this helps.
Here's how check disk (CHKDSK) works...
CHKDSK [volume[[path]filename]]] [/F] [/V] [/R] [/X] [/I] [/C] [/L[:size]]
volume - Specifies the drive letter (followed by a colon), mount point, or volume name.
filename - FAT/FAT32 only: Specifies the files to check for fragmentation.
/F - Fixes errors on the disk.
/V - On FAT/FAT32: Displays the full path and name of every file on the disk. On NTFS: Displays cleanup messages if any.
/R - Locates bad sectors and recovers readable information(implies /F).
/L:size - NTFS only: Changes the log file size to the specified number of kilobytes. If size is not specified, displays current size.
/X - Forces the volume to dismount first if necessary.
All opened handles to the volume would then be invalid (implies /F).
/I - NTFS only: Performs a less vigorous check of index entries.
/C - NTFS only: Skips checking of cycles within the folder structure.
In your case this is the command you would type.
CHKDSK /F /R /I
Note: Use /I parameter only if you're using NTFS.
This command will run a thorough scan on your hard disk sectors and will attempt to recover any corrupted files. It will also fix bad sectors.
If this does not work, then popin the CD and repair XP using the alternate method (not the Recovery Console)... To do this, instead of going to the recovery console, just simply follow the intructions.
If you need further assistance, just email me. sallumuji@gmail.com
Fixboot Writes a new boot sector.
Fixmbr Writes a new master boot record.
THIS IS DONE FOR XP BUT IF THE DISK WONT DO IT IN THE REPAIR CONSOL, HAVE A FRIEND MAKE YOU A SET OF BOOT DISKS. LOOK TO PC WORLD FOR MOR ANSWERS

Doesn't sound very good. XP couldn't repair itself? To be safe I would go out and buy a new hard drive, install it as your master drive and reinstall xp. With your old drive as a slave or a secondary master and you may be able to get some of your files of it
