I have a Compaq Presario SR5610F with an upgraded power supply (Antek 500 watt) and Vista 32 bit. I purchased an ALFA 802.11 b/g usb network adapter which is based on the Realtek RTL8187L Chipset.

Here's the problem. When I plug the adapter into the USB port (doesn't matter which one) and load the drivers, the adapter just cycles on and off. Meaning it appears and disappears on the computer constantly at a rate of about once per second. If you have the device manager open, it appears and disappears under network adapters.

I've tried every driver I can find. I even let windows choose the driver from Windows update. I did a complete system restore (using a different hard drive) back to factory new condition.

Made no difference. Tried a different adapter, did the same thing.
