Below are listed common issues that people tend to run into and their resolution. These are in no particular order.

Computer Doesn't Boot

HDD Not Recognized

Blue Screen of Death

Random Data Loss

Causes reasons include:

  • 1. Improper removal of drive before ejecting it (eg. USB Flash Drive)
  • 2. Corruption of drive, either due to age (average life span of a HDD is between 3 and 5 years) or, in the case of USB Flash Drive's, read/writes.
  • 3. Improper shutdown, such as a power loss (or surge).
  • 4. Malware infection that has deleted your data.


  • 1. Immediately run a backup of the drive with Parted Magic using CloneZilla, and image the whole drive as a precaution. Then, if using Windows, run a 'chkdsk /R' from command prompt from within the OS. Either by pressing F8 when before Windows Logo is shown and selecting 'Safe Boot' with command prompt (recommended) or once logged into windows(not recommended). The computer typically will asked to restart to complete the action and may take several hours to complete depending on the size of the drive. If it cannot repair issues or after repair, corruption (data loss) continues, then you need to replace your HDD immediately as it's failing; boot into Parted_Magic and search the drive for your documents and remove anything you need.
  • 2. If you were infected with malware, such as a virus, then running a chkdsk will not help until you run an antivirus/malware remove program on the drive. There are several anti-malware programs included on UBCD, (eg. AVIRA AntiVir Rescue System). Please run a scan with one of these Tools first, or if you have your own malware scanning application, then use them first and then after removing the infection, run a complete 'chkdsk /r' from command prompt.

Computer is Freezing or Running Slow

This is happens to a lot of people and depends on a lot of factors. I would suggest running over this list in order to find the easiest solution:

  • 1. If computer is freezing, typically points to an overheating issue of a critical component on the motherboard.
  • a. Check all fans are running and if need be, with system plugged IN but power switch OFF, clean out the dust, hair, and balls of lint from the fan grills and Heat Sinks.
  • b. Compressed air (or cans) is not suggested, as it contains water before it evaporates and can cause a short on the motherboard; it but better to use a vacuum with a plastic bristles attachment to clean out stuck on dust.

Again, make sure the computer is PLUGGED IN but POWER SWITCH is OFF. The computer needs to be grounded so you don't short anything on the board, and if it's not plugged in, then the computer isn't grounded and it leaves you the possibility for static electricity to short out your motherboard (common misconception).

  • 2. If the computer is running slower than normal, it may be time to try some basic maintenance
