Used z61m has some serious issues,can u help?

Question

most times works fine,can spend hours on it with no issues.but here are all the things it does.1)sometimes when you cut it on the pointer wont move,and i have to cut it off and back on(sometimes numerous) til works.2)sometimes you can not type in at all in search windows,or email,again have to cut off and on.3)sometimes when writing,say an email,it will just start your line in the middle of a paragraph youve already written.4)sometimes when writing the words actually come out completely backwards.5)if you attach an external mouse and its plugged in when you cut computer on,it beeps at you and will not let you cut it on til you unplug.6)and this is apparently the most serious,when logging off or simply cutting computer off the dreaded "blue screen" appears.i have no idea how to do what it says to correct.it starts" a stop process has been detected and windows has been shut down to protect computer,etc,etc.so is this to much?should i go out and shoot it.

Answer 1

i don't know whether you still have the recovery partition active.
So let's give it a try.
Reboot your computer, then press the thinkvantage button (the blue button next to the volume button on the keyboard).
If you have the partition, then it will take you into a new menu, where you can select restore to factory condition.
And if you can do that, then it is great, just follow the prompt.
