O.P. this post was edited Hi.... My laptop: toshiba satellite l550 ... The part no. Is PSLWSA-01000Q OS: Win 7 32 bit Professional. Problem: let me give you an overview of my laptop.... It was very slow until recently I did a system restore ... It is a laptop with fans that rev all the time and has the ability to overheat and shutoff once the laptop gets to about 105 degrees celsius. My problem today is that I cannot boot the computer past the BIOS ... all the components within the boot menu fail to boot... These consist of in order of my boot settings. 1. P1-Toshiba MK5055GSX 2. P4-MASHITADVDRAM UJ890AS 3. Floppy 4. Realtek Boot Agent When I clicked to try boot the Realtek Boot Agent an error message came up https://www.dropbox.com/s/1unhqan3mrszmlt/2015-07-19 18.08.14.jpg?dl=0 When I press enter on each of these in the boot menu the tells me the part has failed. Please Help me I would like to fix this issue.
