Old pc help

[boredatwork]

So I was brought this old computer with a pentium 4 545 and they told me that it does not give any signal . So i changed the cpu to a pentium 4 845 , and now it gives signal , but it boots into Windows xp , and a couple seconds after it shuts off . The first time , it reached the welcome screen , but now every time I try , it goes out at the same time . The psu is brand new btw.

Any cooler?

The 845 is a Pentium D, not a P4 (essentially two glued P4 dies, though). I'm suspecting a cooling problem. The Pentium D consumes significantly more power than a single P4. Did you clean the cooler and did you reapply thermal paste?

 

edit: p4 545 doesn't exist.

Yes I did , Had to buy new cooling paste . I am using the stock cooler

And also I don't remember if the cpu is exactly an 845 , but I am pretty sure it is.

It's either an 840 or a 945. The 840 is a 130W CPU, where the P4 is only 84 so it might very well be a cooling issue.
