Memory cannot be written error during System Recovery from DVDs

[sveris50]

My notebook is a Toshiba L655-S5150. I am trying to use System Recovery from 4 DVDs to install a new hard drive. I have tried 3 different hard drives and 2 sets of Ram memory sticks, but every time the recovery install fails sometime during the third DVD. The error messages point toward several components: hard drive, DVD drive, memory, and restore media.

Since I've substituted 3 known good hard drives and 2 matched sets of RAM, and the DVD drive seems to work just fine for the first two Recovery DVDs, I'm wondering how to proceed. The most recent error message I received is as follows:

The instruction at 0x77d1205b referenced memory at 0x006d0065. The memory could not be written. Click on OK to terminate the program.

Does memory refer to RAM or the Hard Drive?

Have you contacted Toshiba directly?

Have you contacted Toshiba directly?

Why are you asking yourself that question? Surely you would remember if you had done that?
