We had a power outage. After the outage when I turned my computer on everything worked except for the adapter. When I plug it in it says it is active and the monitor comes up, then it says it cannot associate with access point. When I try to move to the site survey tab, it stops responding, I don't know if some kind of driver got removed or what happened. I don't have the original stuff that came with it because my brother bought and installed it for me. Would there maybe be a way to uninstall and reinstall without having whatever disk came with it. Like a place on the internet that has the drivers or something.

if there is no netework adapter in device manager or any device that is not instaled try checking in BIOS if it is enabled. sometimes after power loss bios is reset. if it is enabled in BIOS that short power outage probably killed your network adapter. you can add some PCI network adapter and solve your problem.
Do you mean the monitor's power light starts green and then turns orange when you turn it on? Most monitors will go to a power saving mode when they do not get a signal from the computer.
The Dell GX260 has a green power light when on. When the computer is off, the light is off. If it is green and blinking, then the computer is in a power saving mode.
Diagnosis: start with the obvious: is the monitor cable plugged into both the computer and the monitor (if not permanently connected to the monitor)? Are you connected to the active port? (You can add a video graphics card in most desktops. The motherboard video port usually needs to be disabled to use the card ports. If you plug in the monitor cable to the disabled port, it won't work.) Is the monitor set to the correct input? (This applies if the monitor has several ports. In that case, there will be a Source or Input button on the monitor.) Is the computer on? The GX260 has the power button on the front. (Other computers have the power button on the top.) There is also the power supply switch on the back which needs to be on.
Next try a different data cable between the monitor and the computer (if you can). Try a different monitor. If a second monitor works, than the monitor has a damaged main board. If the second monitor doesn't work, then the video graphics adapter has probably failed. Replace the add-on card, if in use, then boot in the safe mode to remove the old graphics driver. Then install the correct driver for the graphics adapter.
Note: the computer and the monitor should both be off when you connect the cables. Then turn on the monitor first and set it to the correct source before turning on the computer.)
When the power is returned after a power outage it can cause a power surge and damage electronic equipment such as a computer. This is a reason to install a surge protection power board and connect your computer equipment to a surge protection board. The switch mode power supply may be faulty and replacing it may get your computer operating again. If you cannot DIY then ask a friend or take it to a computer repair shop.
There is only one way to find out if it is an issue with the printer or the Power cord or Power Adapter.
every HP printer has 2 parts. One cord connects the Printer to an
Adapter. the Adapter cord then connects to the Wall outlet.
that you have connected the printer to working outlet, Check after 10-15
mins if the Adapter ( black box ) is warm or cold. If the Adapter is
warm and the green LED light on adapter is glowing, then it could an
issue with the Cord or the Printer.
Try with another Adapter or power cord to diagnose.
For Other brand printers, there should be a power adapter ( black box ) and it should be warm when connected to wall outlet, if it is not warm then it is defective power adapter that you need to replaced. Else it is a problem with printer mechanism.
Is the router plugged into the same power source (surge protector or power strip) as your computer? Try plugging it into a different outlet -- one that you know works -- and if the router doesn't turn on there then either your router is fried or the AC adapter that powers it is fried.
If there isn't any lights on the laptop when it is plugged into the mains supply there is a power problem.
Check the surge protector, has got a reset button?
Plug a lamp into this surge board, if the lamp lights up when the board is connected to the mains then the surge board is OK.
Next check the laptop's power adapter with a multimeter, the voltage reading should be as per the label on the adapter. If the voltage is less than the voltage on the label, then it is faulty and needs to be replaced.
Borrow another adapter to connect to your laptop to see if it powers up or take it to your friendly computer shop to test it.
When this same thing happened to me, I unplugged the Wii power supply from the wall (not just from the back of the Wii) and let it sit unplugged for about 10 minutes. When I plugged it back in, everything was fine.
Try and plug your speakers into a friend's computer and check if they work. If they don't, then the speakers are fried, probably because of a voltage surge when the power went out. If they do work on your friend's computer then you most likely have a bad port on your computer because of the power surge.
