  1. With a new PSU everything points to the mobo since you did not list a GPU I am presuming IGP.
  2. nah no gpu on the mobo only sum sis on brd ***!! i thnk itz sumthin abt the processor chip's contacts corroding (the ones on the mobo) is it a possibility and i dont think that acer used much gold in the contacts
  3. ok brought it to a comp shop they confirmd ma diagnosis the mobo is gone so what can i get dont got much dough and if i do change my mobo w i have to reinstall OS?? i need the mobo to be under 3000 rupees have a look at this site of the local comp store:http://www.theitdepot.com/products-Motherboards_C13.html
