[QUOTE=Tira.linhas;2164718]Dear Fellows! Thank you very much for your concern and for your replies.
Since this is the last, until now, I thank you all here!!!
In fact, a few weeks ago I did a cleaning to my PC. I dusted it as good as I could with a vacuum cleaner and the cooler was extremely dusty. I Thought the problem was there, but no. I bought and applied a new heat paste to the processor, watched the fans…
I think that, as it was noticed in the first reply, the problem with a bad PS is very racional, I mean, when cold, the sistem needs more power to heat and it fails. I borrowed a PS from a friend and this weekend I’ll try to see if this resolves the problem.
I’ll come back here to tell you the result (good, I hope )
Thanks again . Tira[/QUOTE]
As promised, here I am to tell you the news.
Unfortunately, the PSU I borrowed is not working. So, I tried another strategy: I installed XP in an old 80Gb HD I had in my system, I disabled the 300Gb HD and everything is fine, so far. This afternoon, I started my pc with the old instalation and it rebooted, as usual. So, I went to setup, disabled it, enabled the new instalation and… voilÃ ! Is functioning well. But only tomorrow, when starting form cold, I will see if this is really true.
But I’m convinced that the 300Gb HD is not very healthy,in fact!
I’ll com back to tell you the result.
