"...i have got big problem... from past 1 month..."
After what did this first start to happen?
What event happened about a month ago?
A power failure?
Your power supply failed and you replaced it?
You vacuumed the inside of your desktop case?
Why haven't you stated which make and model you have?
We have no idea how old your mboard is and what main chipset it has from the info you have provided.
It sounds like you have a desktop computer, but many people hate the touchpad on laptops and plug in a mouse instead, and some laptops come with a drivers CD they might call a mboard CD.
If you have an Intel main chipset, some 8xx chipsets can't run the hard and optical drives at their full speed until you have loaded the IAA - Intel Application Accelerator.
That's often not included on the mboard CD or drivers CD.
(If the IAA has already been loaded, Intel Application Accelerator is listed in the first Programs list you see in XP.)
Desktop Chipsets ( or Laptop Chipsets, whichever applies)
Choose the chipset series
If the IAA is listed for your chipset, download it and load it.
The IAA must be loaded after the main chipset drivers have been loaded. Intel calls the main chipset drivers download the INF Update Utility. If you're not absolutely sure the main chipset drivers have been loaded, they are at the same place, whether or not the IAA is listed - it does no harm to download the INF Update Utility and load that even if the main chipset drivers have already been installed.
If your mboard has onboard video, the latest available Intel video drivers are also there. In some cases for older 8xx main chipsets, if you load those video drivers rather than ones that were on the mboard CD, you will see an icon in your taskbar that looks like a monitor, and with that you will be able to choose higher resolutions than you could with the older video drivers, and higher than you can in Display Properties - Settings.
According to your info, you have re-loaded Windows twice.
In that case, if the RIGHT click doesn't work properly when you have merely just finished Setup, or you have just finished Setup and have loaded at least the main chipset drivers, your problem cannot be caused by any Windows software setting being wrong because default settings should always work fine.
Does it do this every time, all the time, or just sometimes, such as when you first start up the computer and for a while after that?
If it only does it sometimes, is your hard drive activity led on when it does that?
If the RIGHT click eventually works normally, after you have waited for the hard drive led to go out, there is nothing wrong with your mouse of the USB port you have it plugged into, or the USB circuits on the mboard. Your problem in that case is you're impatient and RIGHT click wasn't working normally because something was using too much of the CPU time.
If RIGHT click never works normally, even when when you wait until the hard drive activity led is not lit up, either you're plugging it into a USB port it can't work properly when plugged into, or you have another hardware problem.
Did you look at my USB port info? (See response 1)
Did you try plugging the mouse in a different port if that info indicates it may not work properly in the port you had it plugged into?
If this is a desktop computer.......
A failing power supply that is not putting out enough of what is supposed to be +5v will cause problems with USB devices.
Go into your mboard's bios Setup. Most bioses can show you the current voltage readings somewhere in Setup - e.g. Hardware Monitor. The +5v reading must be within 10% of 5.0 volts - and the +12v and +3.3v reading must also be within 10% of the nomunal value - if any of them aren't within 10%, you MUST replace the power supply
It's unlikely, but possible, your USB circuits are damaged - a PS/2 mouse may work fine.
Do you have or can you borrow a PS/2 mouse to try?
Some mice are "combo" mice - they can be used with either a USB port, or if you use a simple USB to PS/2 adapter that came with it when it was new, they can also be used with a PS/2 port. If it ain't a combo mouse, a simple USB to PS/2 adapter won't work with it. The labelling on the mouse may make it obvious it's a "combo" mouse - otherwise you can look up it's specsby searching with it's model number.
If it is a"combo" mouse, a simple USB to PS/2 adapter for a keyboard, often colored purple, will often NOT work with a"combo" mouse, and a simple USB to PS/2 adapter for a mouse, often colored green, will often NOT work with a"combo" keyboard, because the necessary wiring isn't there in the simple adapter.
If it's a desktop computer, some mboards develop this problem over time...
Open up your case and examine the mboard to see if you have bad capacitors, and/or other findable signs of mboard damage .
This was the original bad capacitor problem - has some example pictures.
