My sister asked me to fix her lap top. Constant black screen, then BSoD. OK, In safe mode first thing I did - Copied her docs and mp3's onto a USB data traveler. Next I uninstalled as many newly installed programs from the list hoping it's just a driver problem. One thing I noticed she never updated using MS updates. All she had on her OS windows vista home premium 32 bit is SP1. I rebooted running vista normal. Took a look around and again, BSoD. Rebooted in safe mode, went after more junk programs and uninstalled them. Rebooted, again BSoD. OK time to say good bye to the OS and run the recovery disks that came with it. I went in the BIOS and set priority to boot up on the disk drive. Rebooted, inserted recovery Disk 1 - running, set to restore to "Out of box state"... half way through the recovery disk 1 - BSoD. OK now what I'm thinking! Run the recovery disk and repeat erasing the HDD. Done! Rebooted - ran the recovery disk 1 again to start all over, set it to out of box state. Again half way through - BSoD. Next: OK, Time to go after memory sticks see if memory sticks are causing the problem. Two sticks came with the lap top - upper stick is 1GB & lower stick 2GB's. (3GB total) Removed sticks....replaced to lower slot the 1GB stick, kept the 2GB out. Rebooted to the disk drive and ran recovery disk 1 set to out of box state on a clean erased HDD running 1GB of memory only. As I'm typing here, I'm running recovery disk 1 It goes through building the partition, copying files.......WOW this is a first... asking to insert recovery disk 2 ....copying files - Now recoverying, please wait! ........I'll get back to you shortly
