after a day, when i switched on my pc, my smps became dead suddenly. i bought a new smps and it worked fine without any problem.
2 days later, certain keys ( z, a, q, 1 and esc ) on my keyboard stopped working. i replaced it with another one - not new. but all the keys were worked.
after a day, while browsing, my zone alarm pro indicated 'sethc.exe' tried to do 'something'. i choose to allow this operation. suddenly, some other keys stops functioning - pgdown,end, 1, 2,3,4,7,8,9,0 (keys below f series)
i suspected it might be a virus and scanned my harddisk for viruses, spywares, etc. nothing worth to find the problem. no virus, no spywares....
strange and funny.
what shall i do?
guys, plz suggest.
thanks in advance.
