Hello. Ive been trying to fix a friends laptop.its a gateway W350A T-Series 1616.Windows vista home premium..i started with many errors.using ubuntu live cds have fixed all but 1 thats driving me nuts. ive tried to install xp but upon formatting it gets to 100% and says cannot formatt. so i got new recovery disk and when it trys to format it gives this error, The instruction at 0x775e2b11 referenced memory at 0x7aa50b1c The memory could not be read click ok to terminate.ive tested the memory and checks fine. When i try to use the OS cd it gets to step 2 and gives me this error, could not assign a drive letter..so neither original OS disk will work nor the new restore cds.its got me stumped...any ideas ive read alot on refrence errors but none have the same error number as mine...
