“Take good care of your PC, and it will take good care of you.”

It’s a nice sentiment, but reality is more like “Take good care of your PC, and it won’t crash, lose your data, and cost you your job–probably.” Follow these steps to stop PC problems before they stop you.

Your PC’s two mortal enemies are heat and moisture. Excess heat accelerates the deterioration of the delicate circuits in your system. The most common causes of overheating are dust and dirt: Clogged vents and CPU cooling fans can keep heat-dissipating air from moving through the case, and even a thin coating of dust or dirt can raise the temperature of your machine’s components.

Any grime, but especially the residue of cigarette smoke, can corrode exposed metal contacts. That’s why it pays to keep your system clean, inside and out.

If your PC resides in a relatively clean, climate-controlled environment, an annual cleaning should be sufficient. But in most real-world locations, such as dusty offices or shop floors, your system may need a cleaning every few months.

All you need are lint-free wipes, a can of compressed air, a few drops of a mild cleaning solution such as Formula 409 or Simple Green in a bowl of water, and an antistatic wrist strap to protect your system when you clean inside the case. (more…)

1. First, run a scandisk or checkdisk. Let Windows fix any errors.

2. Run a disk cleanup utility…this will flush your temporary internet folder, trash can, temp system files, etc.

3. Delete any garbage files or data…if possible, run a Duplicate File Finder program.

4. Run Defrag on all partitions (NOTE: run this after you have deleted all trash and excess files!)

5. Run a registry cleaner utility and delete or get rid of any orphaned entries in that registry.

6. Check your exisiting swap file for it’s size and location (*will explain location later in the post). If you have alot of ram (i.e. 1 gig and over) set this swap file to something small, like 250 mb. The reason is that this will force Windows to load more into memory, resulting in faster performance (note: some games and applications actually require a certain sized swap file so check your applications performance after making a size adjustment for any error messages.)

How to Bypass BIOS Passwords

BIOS passwords can add an extra layer of security for desktop and laptop computers. They are used to either prevent a user from changing the BIOS settings or to prevent the PC from booting without a password. Unfortunately, BIOS passwords can also be a liability if a user forgets their password, or changes the password to intentionally lock out the corporate IT department. Sending the unit back to the manufacturer to have the BIOS reset can be expensive and is usually not covered in the warranty. Never fear, all is not lost. There are a few known backdoors and other tricks of the trade that can be used to bypass or reset the BIOS

DISCLAIMER
This article is intended for IT Professionals and systems administrators with experience servicing computer hardware. It is not intended for home users, hackers, or computer thieves attempting to crack the password on a stolen PC. Please do not attempt any of these procedures if you are unfamiliar with computer hardware, and please use this information responsibly.

Before attempting to bypass the BIOS password on a computer, please take a minute to contact the hardware manufacturer support staff directly and ask for their recommended methods of bypassing the BIOS security. In the event the manufacturer cannot (or will not) help you, there are a number of methods that can be used to bypass or reset the BIOS password yourself. They include: (more…)

Hard drive gone bad

The most common problems originate from corruption of the master boot record, FAT, or directory. Those are soft problems which can usually be taken care of with a combination of tools like Fdisk /mbr to refresh the master boot record followed by a reboot and Norton disk doctor or Spinneret.

The most common hardware problems are a bad controller, a bad drive motor, or a bad head mechanism.

1. Can the BIOS see and identify the hard drive correctly? If it can’t, then the hard drives onboard controller is bad.

2. Does the drive spin and maintain a constant velocity? If it does, that’s good news. The motor is functioning.

3. If the drive surges and dies, the most likely cause is a bad controller (assuming the drive is cool). A gate allowing the current to drive the motor may not be staying open. The drive needs a new controller. (more…)

Here’s a DOS trick for Windows 9x, that will reset (delete) your motherboard’s BIOS password (aka CMOS password) without any need to open up your computer to remove the battery or mess with jumpers.

This method can come in very handy in the event you ever lose and forget your BIOS password or if you acquire used computers where the unknown previous owners had BIOS passwords set (in fact, this happened to me long ago-I was given a used computer, but there was no way I could enter the CMOS to make changes). It’s important to note here that the password we are talking about is only the one that prevents a user from entering the BIOS setup at bootup, not the one that stops you from getting past the boot.

Normally, at bootup you can press a key (usually the DEL key) to access your BIOS allowing you to view it or make changes. With a password set, there is no way to enter setup. Though a password can provide a basic and very effective level of PC security, losing it can be a real headache if you don’t know how to fix the problem. (more…)
