My toshiba A200 laptop was upgraded from vista HP to ultimate with a clean install on new 500gb hard drive and it has worked pretty flawlessly for the past few years from the RC version. But in the past few months it has started crashing, rebooting and rebooting and rebooting, now freezing when inserting power cable [with buzzing sound] been very hard to start sometimes rebooting in a loop. Starts ok usually on battery only but erratic on cable. Not really sure what the cause is but am assuming it is updates as i have done clean install on yet another hard drive and after doing updates it starts to crash, uninstalling SP1 by restoring doesnt make a difference it is still stuffed. I have 3gb of ram.
when i put the original vista drive back in it works fine.
but want to stay with windows 7.
Toshiba says there is no Bios update past 2.5, all the drivers as far as i can ascertain are up to date. Not sure which update is causing this. the minidump doesnt work and event viewer just says there is a kernal issue and the laptop closed down unexpectedly so doesnt help much.
Any help appreciated.
