No mention of age, if you keep the vents dusted out, the spyware off the machine, if it's XP SP2, the driver updated and more.
With such a slim post, your next step is to tell a longer story.
I don't know if this is where my question goes and I don't know what I'm taking about but I'll ask anyways. I have a laptop (acer), when I was using it yesterday it turned off by itself when I turned it back on it said Sorry for the inconvenience Windows can not start properly because of new hardware or software. Then now at the bottom you could choose from safemode, start normally, start from the last know good configuration. It was something like that so I've tried a couple of them and all of them do the same thing. Windows will begin to load then a blue screen appears. I haven't been able to read what it all says because it stays up for 5 seconds then turns off, restarts by itself and does the whole thing over again. But I did catch some stuff. Something about shadowing, disable bios options, press f8, advance start up options. I have no clue what's wrong.
