I'm sorry I don't get it. You said,"asus mother board p5sd2 is not supporting graphics", is it graphics of gaming, or graphic card? You also said,"The main problem of my graphic card it is not supporting high graphic games", what graphic card do you referring, onboard graphic card that on the p5sd2 or discrete graphic card?
I have the same problem and have it solved (50%). My laptop went white when start and there is startup sound and I able to shutdown via keyboard shortcut. In my case, it's the cable that conect LCD with the Motherboard. I open up my laptop (the whole shebang), and I ended up with a cable that only need a little push. It loosen from the "place-it-should-be". Now I got it, but every time I start up my laptop, i have to push the cable. For the record, i let some of the casing open so I can push the cable. Here is the picture. That 2 cable is connecting the LCD panel with the motherboard. Only with the push, it'll work. I hope you guys have the same "easy" problem. For the record, this cable worth Rp 400.000 in USD, it's about $44. I rather using the push than purchasing a new cable. :D
I've seen a virus that scrambled mouse input, but it's not making the infected get stop working. Maybe the virus get crashed with other program. IF, you do have the same virus, try to remove the virus 1st, than see what happen.
It is depends of your device, see the tear down section and follow the instruction until the home button removed. If you not familiar with this friendly-UI website, you can use the search box at the upper right corner, just write the device you have, and the result contains everything (repair manuals, teardowns, questions, etc).
Where did you get that message? after or before OS selection? Update: Well then, that's mean a lot possibility ahead of us. Try changing the RAM with other RAM, or simply change the DIMM slot to the other that not used. And clean the yellow stuff (the pins) with a rubber. Let see if that work or not. One more thing, reset the BIOS setting with the jumper.
