Death By Dust

Saturday, December 3rd, 2011

When we repair a computer at my PC Techs, one of the first items on our list of work to perform is dust removal. In Arizona, dust is a big problem and coats everything. When a new computer comes into our shop we never really know just how much dust we are going to see! It’s always a surprise when you “pop the case” of a computer for the first time.

Here are a few pictures of the inside of a case that recently came into our workshop.

Over time, dust can cause internals components to overheat, due to lack of air circulation

Dust is a slow computer killer. Dust prevents normal air circulation through the computer case. The case draws cooler air from outside the case through the various airflow openings of the case. The lack of circulation caused by dust will often result in internal component overheating and failure. These include video cards, hard drives, computer processor and other internal hardware.

Common intake openings of the case include the front and the sides of the case, while exit openings include fans usually mounted in the rear of the case and the power supply.

Keeping these openings clear of debris can help to maintain the proper airflow around the case. A good practice is to also maintain four to six inches of clearance from the computer to any object which could block airflow.

In conclusion, dusting out your case every month can help to extend the life of your computer – instead of it suffering the fate of death by dust.

Keeping technology working, so you can too!

Wednesday, September 8th, 2010

Can anyone name a small business, or any business for that matter, that doesn’t rely upon technology for day to day operations? Computers play such an integrated role in our lives. Much like automobiles, it is important to maintain your computers and run periodic checks on them to avoid failure.

When doing routine system maintenance, there are several different areas of the computer that should be checked for potential problems. The operating system itself, installed software, updates and patches, anti-virus definitions, the network settings, the system fans, dust levels, hard disk drives, backups, and external devices! Some are more important than others. For example, if your hard drive fails, you could face some very costly data recovery issues. Dust is another one, dust and heat are the biggest killers of electronic components. A competent computer repair firm will have a checklist of items that a technician will run through, the hard drive and dust levels being just one of those, to ensure optimal performance.

Not to get stuck on the automobile analogy, but it’s so easy to do comparisons between that and computer repair. If you forget to change your oil, over time your engine suffers. If you go long enough, eventually your engine will fail. Computer maintenance is the same way. A lot of clients have come to us with failed hard drives. Sometimes we can get their data off pretty easily and recover their systems. In the worst cases, those hard drives need to be sent off to a lab where data recovery becomes extremely costly. Client with crashed hard drives are usually surprised when we tell them that the crash could have been avoided. There are warning signs that most equipment will give when things go bad, and the signs usually begin a while before the actual crash takes place. For hard drives, it could be slow performance, errors while working, errors in system logs, or even clicking or grinding sounds. Most computer fans make noises too when they are about to fail.

Our experts service and repair machines and are experienced in the different ways you can identify computer problems. If you hire a team of professionals that know how to keep your computers working, and have them come out monthly for a quick checkup, you too will be able to keep working. For most people, computer failures usually happen at the worst possible time. Like, right before an important project deadline. If your computer suddenly crashes or the network is not working you may lose work and income. All of this could be avoided with just a couple hours of preventative maintenance per month.
