USB not decting plug n play devices

I have a Compaq Presario SR1320NX Desktop PC with a 2.0GHz AMD Sempron 3100+ processor. The problem is when I try to use the USB ports its not detecting plug-n-play devices or if it does detect the device on initial setup it doesn’t properly install the drivers. I’ve tried the P-n-P devices on several other computers and they load the drivers and play them just fine. Do I need new AMD chipset drivers to get new USB drivers or is there something else that can be done to fix this problem? Please help?

Re: USB not decting plug n play devices

I would check the bios settings to make sure the motherboard settings relating to PnP are correct. Try playing around with those bios settings and see what works for you. Also try different usb ports, i have the same problems sometimes with certain ports on my desktop computer, try all of them at the front or the back of the computer. I would check the Compaq Presario website for drivers not AMD, installing new ones is a good idea just to make sure its not a driver issue.

I don't know any processors that would be compatible with my Compaq Presario SR1810NX and I'd like to upgrade it. Any help would be appreciated!

The mother board will support any Socket 939 AMD Athlon X2 Processor upto the 4800+ model.

However Socket 939 Processors were discontinued so you may have a hard time finding a "New" one.

The controller will not turn on. Green light on back comes on but when we turn on the unit, the fan starts briefly and then the power cuts off.

Bad Power Supply. Weak Voltage power rail.

Not enough power to turn the Processor on, and keep it on.

1) ALL those LED lights together, use less than 1 Watt of power.

2) EACH fan uses 2 to 3 Watts

3) A typical Processor can use 51 to 125 Watts. Depends on what Processor it is. (Older Processors use less Wattage)

The Compaq Presario SR1810NX desktop computer, comes with an AMD Sempron 3200+, processor.

(Uses the Socket 939 processor socket)

[Maximum operating capability is a 1.8GigaHertz frequency rate.

Giga = Approximately 1 Billion
Hertz stands for Cycles per Second.
Frequency Rate is correct computer speak for 'Speed'
The AMD Sempron 3200+ processor, can operate at a maximum frequency rate of 1.8 Billion Cycles per Second ]

HP Support >Compaq Presario SR1810NX desktop computer > Product Information > Product Specifications,

The AMD Sempron 3200+, can use up to 62 Watts,

(Palermo Core)

When you press the plastic Power On button, you are contacting a Power On switch inside it.
(Typical ATX Power On switch, )

When an ATX power supply is plugged into power, there is a 5 Volt Standby power, present inside the power supply.

Pressing the momentary contact power on switch, closes a circuit that directs the 5 Volt Standby power to 'excite' the power supply, and turn it on.

The first chip to receive power is the BIOS chip.
[Chip and Chipset are slang terms for I.C.
Integrated Circuit.
BIOS stands for Basic Input/Output System]


BIOS looks to see what devices are installed, does a Ram Memory count, TURNS the Processor on, and hands the computer over to the Operating System.
(Windows XP is one example of an O/S. Operating System)

The LED lights receive power, so do the fans, and the Harddrive. When it's time for the Processor to kick on, there isn't enough power, and the Power Supply 'falls to it's knees'.

Replace the Power Supply.
It's just one of the basic ATX power supply's that are readily available in a multitude of places.
The Wattage is 300 Watts.

The ATX form factor for this power supply, (Size and shape), is approximately 6 inches Long, 6 inches Wide, and 3-1/2 inches Tall.

I have a compaq sr1603wm and I was wondering what motherboard I can use to replace the stock one and if I would need to replace the power and or fan thanks..

You need and AMD motherboard that supports the Sempron processor -939 Socket. It's a little difficult to find them now, but they are still available. Since you have a brand computer. You make have to give up some perks like front usb port or the audio cable might be too short to mount on the new board. Be prepared for some compromise when installing a different board.
