Pop-ups appear while the computer is running.

Adware infestation. Boot up in Safe Mode, then run a spyware scan and delete all spyware entries that pop up. I've heard that Hitman Pro is a good free program that can detect most spyware with the fact that it has many different antispyware database files in it.

No sound is coming out from my computer.

  *Check all cables and reconnect if necessary. Make sure the audio cable is connected to Headphone.

* Check the power of your speakers and make sure it's on.

* Check the volume in Windows, or of the program you're using. Unmute everything except Microphone, and drag everything else up.

* Test out the speakers with another device. Plug it into your iPod, TV, whatever you have. If there's no sound, replace the speakers.

* Check if the audio card driver is even installed. Go to Control Panel, then Sounds and Audio Devices, and if the model of your audio card pops up, the driver is installed. If nothing appears, download and install the driver.

* Enable the Windows Audio service. Go to Control Panel, click Classic View, then go to Administrative Tools, then Services. Look for a Windows Audio service, then enable it. If it asks that all other services related to it should be enabled, enable those too, then re-enable Windows Audio.

* Test out the audio card. Plug it into another computer, install its drivers, and test it out.

* Post the problem in the Tech Support thread and don't forget to note that you've already followed the solutions in this guide.

* Replace the audio card.

Boot-up takes a long time.

  *Determine whether this is abnormally long. If it takes 30 seconds to 3 minutes or so, it's just the fact that you're loading up loads of drivers. Keep reading on for just a few more tips. If it's long as in 30 minutes to hours, then it's a sign that the boot file might be corrupt. All I can suggest is: - System Restore - Repair installation - Reformat.

* If it's not abnormally long: I'd recommend you try disabling startup entries.

* Run a program like BootVis. You can find tutorials on how to use it online.
