My TOSHIBA® Satellite 1900-203 Pentium 4 1.7GHz laptop does not boot up. The problem was the CD/DVD drive was not working ie not reading most CD's except for the Toshiba system CD.Thinking it was a BIOS problem went to toshiba site and updated the BIOS version TR20100A. After that the system does not boot up ie it is just dead.Took to one of the local agents and they say need to replace the mother board which is costing around $350. Need help as to how to recover,is it a motherboard problem? So do I need to spend $350 looks like buying a new laptop would be better!. Iam located in middle east BAHRAIN,ARABIAN GULF.Please help. Thankyou guys in advance.
