Computer restart issue (re-install the system for that matter) is a hardware problem?

Users questions: Always automatic restart the computer while ago, then reinstall the system, the problem remains after reinstalling the computer did not install any new equipment recently (for a usb mouse is not a bar -_-!! new equipment that is several weeks earlier things.) fault performance as follows: 1: reboot often seems to run several programs are For example there is a second open listening Pros, landing qq, visit the web industry at the same time give me restarted. 2: enter the game all the more easy to restart, but entered the game after the success can usually play for hours no problem. 3: 1 browse network has been tried when the industry (and not running any other programs) also emerged from Fixed restart behavior 4: 2 times even more strange, with a sudden with the automatic shutdown of the (computer screen is not connected signal lines, usually after the show that was shut down), but the num keys keyboard and mouse signals the lights , listen to sound as if the hard disk is still operational. 5: Na Quxiu computer, where watched, said the computer repair My version of the capacitance of the main storm the two, there are more than 10 drum out, that want to change capacitor to dozens of blocks (tens of dozens of blocks on the block, but the father told him that the students look-_-! ! Finally, he moved to his fellow students to host home for a few days, even saying that there no problems, everything is normal. Khan!! finally moved back to my home, asked Title again). 6: add a point, where the host computer in the revised test is used when the usb mouse (I do not know why did they move him, ps interface to the mouse impossible, before also), the father of my friend's house at all clear What he mouse, I do not think things off right now! ! Said that What more, you look hard, and finally ask the next question in the end is not a hardware problem (for example, who said the capacitor is broken), and, bad capacitor look like? I read my capacitors, and some really drum up a little bit more, there are two surface rust as some of the powder, which is really the reason the computer restart It? Usb mouse and it still relevant, or is a special cow b virus trouble, is no time to engage in capacitance problem recently, it came clear to point! ! Thank
Experts answer: repair shops do not lie to you, the main version of capacitors are questionable, resulting in insufficient power supply, run a little big of a program or a large web page, can be Can restart. Dozens of dollars is not expensive, generally require 200 Caixing. Or let people repair it. No problem with friends, maybe he did not run large programs.
