Very slow behavior in Personal Computer solved
The PC with the following features was having a very very slow behavior; in short it was almost impossible to operate:
- Motherboard INTEL DG35EC.
- 1GB of RAM memory (DDR2/800MHz).
- INTEL(R) Pentium(R) Dual CPU E2180 @2.00GHz
- Two HDDs: SAMSUNG HD161HJ (160GB) and SAMSUNG HD502HJ (500GB)
- Two optical units: LITE-ON DVDRW LH-18A1P and CD Drive LG 52x.
The Operating System Windows XP Professional SP3 had been already installed and the trouble persisted yet, therefore, the PC was opened by its side and the job began.
From now on, it will be described the different steps (step by step) taken into consideration:
- The RAM memory (only one module) was cleaned and checked.
- The Microprocessor was cleaned and checked.
- The fan and its radiator (it was free of dust) of the Microprocessor were checked too.
- Both optical units were disconnected from data and voltage.
- Both Hard Disk Drives were unplugged from data and voltage.
- The Floppy Disk Drive was unplugged from data and voltage too.
- The internal DC Power Supply was checked.
- The Motherboard was inspected, and not any component burst, nor overheated neither anything abnormal.
So far, everything kept the same situation.
At the end the Multi Flash USB Card Reader was unplugged from data and voltage signals, and when the PC was turned on again, what a surprise! The slow behavior had disappeared completely. Here are some photos of this out of order device.
This device was disarmed to find out the cause of the abnormal operation of the PC, and a photo is shown.
The pins were put at their original position as you can see from the photo below:
The Device was armed again and not connected into the Motherboard, because it was completely out of order, but never mind, the principal trouble which caused the slow behavior had been detected: a malfunction of the Multi Flash USB Card Reader, which is a very cheap appliance in the market.
At the end of the job the hole which had let the broken device in the front of the PC chassis was covered with a plastic cap to protect all the system.
