Specs: Fendora for now
I need as little information. This is the first computer that I have built. Well its all second hand things. But it is a start. Well anyways I have a Asus P5LD2 mobo. It has a 1.8 dual core. So I decided that I would upgrade the CPU. So I got a Intel Pentium D 940 (OEM) 3.2GHz Dual-Core chip. I did a ton of research of what CPU I could use. When I first install the chip the computer would boot up then cut off. I tried a few more times. The system would start then shut off. I played with the bios setting with the old chip install. Once I placed the 3.2 in. I got the the log in screen. Then the computer cut off. The processor was hot to the touch. I waited till the chip cooled then I booted once more to see if the computer notice the chip. It did so I turned the system off. I got the arctic paste for the CPU. But I think that I need a better cooling fan. The fan that I got in there now is the one for the 1.8. I need to know what is a good heat sink and fan? I hope that the chip was not damage. I guess you live and learn.

As of right now the power supply that is in the computer is a 400w I believe. This will not be the one that I will be using. I am just testing parts before I place them in the case I will be using. I will be using a 600 w when it is all said and done.

Unless your "1.8 dual core" is a Celeron Dual-Core, it's a little faster than the 3.2GHz Pentium D that you replaced it with!

The Pentium D is based on the old P4 "Netburst" technology. It runs hot, eats power for brekky, and doesn't accomplish much per clock cycle.

Your 1.8GHz chip, whether it's a Pentium Dual-Core or a Core 2 Duo, is based on newer, far more efficient Core 2 technology. It doesn't produce as much heat, merely sips electricity, and does a lot more work per clock cycle. General rule of thumb is that, in order to match the processing power of a Core 2-based chip with a Netburst CPU, you'd have to double the clock speed. You'd need a 3.6GHz Netburst to match the number crunching power of a 1.8GHz Core 2.

Send that Pentium D back to where it came from and plug the 1.8GHz Pentium Dual-Core/Core 2 Duo back in. Or upgrade to a 2.66+GHz Core 2 Duo if you need a little more oomph. Either way, you'll thank yourself when the power bill comes in. :)

jackbomb covered the CPU issue so I'll address the PSU. 400W isn't necessarily bad, 600W isn't necessarily all depends on the make/model of the PSU & it's amperage specs. Before running out & buying a new PSU, post the specs of the one you have, it *may* be adequate for your needs.

Which video card will you be running? How many HDD's & optical drives?

I should have checked here. I was told that this chip was better. I guess that I will be stuck with the chip. Where I got it from has a no return policy.As for drives. I will be using a plexter daul layer burner and a tdk cdr. I got two drives a 500 gig seagate and a 80 gig maxtor. Both are sata drives and I have a 8600 geforce video card and a linksys network card.
