sir in my network i have 90 systems .among those some 5 systems behaving stranger since last few weeks .they are restting automatically while copying some thing or opening an application outlook express , acrobat reader , some dos application ...plz tell me the solution .....
 
Possible causes:

-Everything not completely seated on the motherboard.
Reseat everything.

-Overheating
Clean out any dust.
Check the system and CPU's temps either in BIOS or with temperature monitoring software.
If the system temp gets over 45 deg. C, then remove the computer's cover, and run an external fan. If this fixes things, then install additional case fans. Recommended locations are lower front and upper rear of the case.
If the CPU gets over 60 deg. C, then make sure there is thermal compound between it and the heat sink. If that's ok, then replace the compound with Arctic Silver3.
If no luck, then install a higher capacity heat sink fan.
If still no luck, then replace the heatsink with a more efficient unit.

-Overtaxed or bad power supply
Swap it out with a different(preferably higher wattage) unit.

-Bad memory
Remove and reinsert the memory a few times, try it in different slots, do not use any optimal settings for the memory in BIOS, increase the memory's voltage a notch in BIOS, and swap it out with known good memory.
Also, do not mix parity and non-parity memory.

-Bad video card.
Swap it out with a known good card.

-Bad MB.
Swap it out with a known good MB.

-IRQ conflict with a network card.
If no problems show up for the NIC in Device Manager, then remove it from DM, shut down, uninstall the card, and restart.

-Check for viruses and spyware.

-Uninstall kazaa.
 
I would scan for the Blaster Worm. It could cause symptoms like you have discribed.
