Hi All, My SONY VGN-TX670P B netbook, which runs on Windows XP randomly freezes or crashes. I tried restoring to the factory mode but still problem persists. I have also installed Hard Disk Sentinel to scan for any possible HDD errors, however there seems to be no bad sectors and the Hard disk is in 100% health. What could be the possible reason. Should I upgrade to Win7/ Win 8. I have just 1 Gb Ram and the maximum it supports is 1.5GB. Would it be a problem with the hard disk or some BIOS/ motherboard issue. The system is too good to be discarded yet !!
