Comp Buggy Blueprint My Computer Crashes Every 5 Minutes And I Cant Use It To Do Anything Now. What Do I Do?

My computer crashes every 5 minutes and i cant use it to do anything now. What do i do? - comp buggy blueprint

The problem began yesterday. My team has done well, but then crashed when running a program. So I had to make an end and start the comp again. Team is working well after a while, but the program is run errors and crashes and I had to continue until the end disk. share, and sometimes during this scenario, an end to almost 30 that I do a lot of time for all accidents. But now my habit, and even a model of the last 5 minutes before it crashed, and that the program will not run. I uninstalled and then I have an accident after 5 minutes. and the launch will take a long time to occur in certain regions and even today, not always, of course, freezes at startup as well. even freeze on the BIOS. so now I'm stuck. I tried to re-install Vista and frozen in the middle of the shift and then run again and complete, but it still crashes. So at guessing the motherboard is ruined, because if the power supply, which was closed after the accident, it wouldnt? and I can not completely restore the software model and the reinsShaped and even tried changing wireless cards and mouse / keyboard. I ran the HP diagnostics and says hard drive memory and CPU all the tests.
pleeeaaase help meee. I can not use this thing, however, that all minutes from 5th Actually havnt even managed to overcome the initial configuration pages of time and things, if you reinstall Vista. (with a dif. comp)
