i have the same problem i think that it is most likely a cooling problem the computer turns on over heats freezes and shuts down

sori about that,but i advise you to check on your RAM. it should have stopped working.isaac

open it with safe mode by pressing f8 while the computer it start booting

actually all i needed to do was tighten the fan and cooling assembly the laptop is design flawed

Hi I passing from the same situation with a new pc im building and thats hardware problem, what i can say is that i have replace almost all the new components and not have sucess im thinking that the last thins is that im using an old cpu core from myex computer that the mother board burndown soo im thinking that for a pc start and mostly magically turn off without showing the bios screen it can be that the processor is dying you should check if someone have a processor from your same slot and test it to check if is your processor or you motherboar thats the only thinks that can happen The processor or the motherboard i hope this can help you out with your problem.

Was this issue resolved? I am having an identical problem. Ihave checked all the fans in the case, including the fans to the PSU and the Vid Card. Mine will not even make it to the windows screen before shutting down. I have tried using safemode, and my copy of UCBD (bootdisc). I have also checked the ram with new sticks, and even went as far as to buy a higher wattage PSU, and swap out video cards, to find that those didnt work either. Is there anyway to test the Motho with the p.c. shutting down like this?

Yes I think so, I phoned a computer geek and he came to my house with a bit of kit that he plugged into my motherboard and somehow tested it. It was quite some time ago now so I can't remember what it was. The verdict was I needed a new one! He only charged me £10.
