Question about Toshiba Satellite A105 Notebook
After using a cd rom my laptop screen has turned upside down this happened a few years ago and fixed it in the end but can't remember how. Ctrl alt and arrows don't work or ctrl alt r. There is no rotation option in the graphic's properties so cant change it that way. Any other suggestions? Thanks a million - have been trying all day.
Nope. Hold the CTRL key and the ALT key down, and at the SAME time tap on the Up arrow key. That\'s about it

SOURCE: Laptop will not come on
Although other possibilities can be at fault, if it does so little after power on, the CPU itself may have failed.
The very first actions a PC does when turned on is to read the information stored in the CMOS to determine what hardware is on board.
After doing this, it turns to the hard drive for a check to see if it is readable and then the CPU (your microprocessor) Intel or AMD takes command.
If the hard drive is at fault, a message will inform you that the hard drive either cannot be found or is unreadable.
If the hard drive light flashes once, then the BIOS has made contact and then the hand-off to the CPU begins.
If it is stopping dead at that point, the CPU is the prime suspect.
What fairly often happens is first a failure of the CPU fan that sits directly on the heatsink that transfers the heat from the CPU and then the heatsink is bathed in air from the fan. If the fan has failed (all too common) or is impeded by a dust accumulation, the CPU overheats and if the maker has not made any provisions to shut down the CPU, it dies.
There is a possibility that this kind of problem can be caused by a failure of the RAM (memory) but establishing what has failed is only possible through substitution of one or both of those devices.
If you are somewhat skilled, opening a laptop requires small Phillips screwdrivers to remove case screws from the side(s) and bottom, then the case still (in most cases) needs to be carefully pried open. The mating halves normally snap together as well as being fastened with said screws.
Most likely the keyboard will also have to be freed from a couple of screws and, depending on the length of the flat cable connecting it to the system board, can be pulled forward before or after the cable is pulled.
The CPU will be easy to spot; it's one of the large clumps on the board. Check its fan to see if the blade turns freely and is not impeded by dust (these things have hardly any torque), then with two fingers, positioned on either side of the blade, check to see if it rocks side to side. This would be an indication that the bearings have failed and it will need to be replaced. The CPU is held by clips but make sure you have no static charge before removing any internal part. Just 'equalize' the charge by touching an exposed metal cover or other chassis part. Memory is normally accessible from the bottom of the case.
Now comes the bad news; there are still myriad other components that can keep a PC from booting when no error message is present since there are numerous support functions which can interfere with the startup of system. I've given you the most likely points of failure; CPU or memory.

You most likely have a faulty hard drive, especially if it is making a clicking sound.
You wil need to purchase a new hard drive and install Windows again with the Toshiba Recovery CD.

Usually in disk read errors are because of bad HDD.
So get it checked by the service center so that the issue could be fixed.
