Need ethernet controller/LAN driver for HP a1620n

I have tracked down that this computer runs on Win XP 64 bit I sure hope this is correct because the processor is a 64 bit processor. And you can access the download for the drivers you need from Here. I am also going to leave you with the websites I looked at to determine what the computer is and all it's specs. which were 2 websites the first one Here and the second one Here. If you need anymore help just ask. Thanks, Cody

Hp Pavilion a1620n seems completely dead. Went through a diagnostic and presumed the ps was burnt out. Have since seen the ps light on while all internal cables are unplugged. Can plug all cables in and ps...

No, it indicates a bad power supply.

1) ALL the lights use less than 1 Watt
2) EACH fan uses 2 to 3 Watts

3) A typical processor uses 55 to 125 WATTS.

The base model of the HP Pavilion a1620n Desktop PC, comes with an Intel Pentium D 925
(Operates at a maximum of 3.0GHz)

The Intel Pentium D 925 uses 95 Watts,

In most cases the inside of the computer is dirty, as well as the inside of the Power Supply, and it's fan.

Heat = Wasted Energy
When the Heatsinks inside a power supply, and it's Fan, (To include the fan blades, fan center hub, and surrounding fan cage), become clogged with gunk, the cooling capacity of the power supply drops tremendously.

Since Heat = Wasted Energy the power supply tries to keep up with the power load demands.
Eventually components inside the power supply fail.

(Usually the Electrolytic Capacitors are the first to go)

The power supply inside a Pavilion a1620n is a common SMPS. Switched Mode Power Supply.

The style is the common ATX, that is used in over 90 percent of desktop computers. (ATX 12V)

The Wattage is 300 Watts.

Should you like help in finding a replacement power supply that is affordable, and reliable, just state so in an additional comment.

I do advise staying away from the cheap generic models, as they can fail in 6 days to 6 months. ($20 to $25 range)

HP Pavilion a1620n monitor won't display

If you have TWO graphics ports (one onboard + one seperate card) then double check you are plugged into the right one !

If you get the same issue with another monitor then it is more than likely that your graphics card is pooched.
If you are using the onboard then you can buy a pci express card to replace / bypass the onboard.
If you are already using a seperate graphics card you may well need mo replace it.

This is the motherboard for your machine. Remember that if you dont use the onboard graphics you should got into the bios and tell it which you want as primary dislay adapter

What kind of fan is it and what are the volts and the amps it makes a difference if they are not close or the same as the original/ is it plugged into the mobo or is it a tap in on the power supply's large white y/r/b/r/wires this kind is not good for the cpu fans. let me know i will help
