Recently I saw many tiny ants roaming around my kitchen top; and then I saw these ants also around my working table. At first I tried using lemon juice mixed with water and spray it on the area frequent by the ants. This method worked for a few days and then the ants came back again.
So I decided to get some ant baits and I bought the Bagyon Ant Baits. I put it at the kitchen top and table where the tiny ants were frequently found. From my observation, I noticed that the ants were still there but it was not attracted to the baits. The tiny ants simply walk around the plastic frame of the baits and not getting inside to feed. After a few days, with the ants still roaming around, the Baygon Ant Baits was simply not effective at all for getting rid of these tiny ants.
My next step was to buy boric acid powder which I saw at the supermarket shelf. I put some of this powder on a container, add sugar ( brown and white ) and water. You can used any type of sugar; 2 teaspoon of sugar and small amount of water. Then I stirred it until it became a paste. I placed this sticky paste on the kitchen top and table. An hour later, I saw many tiny ants eating the baits of this boric powder paste. Thereafter there were more and more ants roaming around and it was attracted to this bait. I believe the sweet sugar added to the boric acid powder must have attracted these tiny ants to a frenzy feed.
The next morning, all the tiny ants on the kitchen top and table were gone. There were ants lying dead on the table. I remove the boric acid paste and the dead ants using a damp cloth. For more than a week now, there was no sight of these tiny ants in my home.
After buying a new Lenovo Notebook, I noticed that the notebook tends to get quite warm around the keypad area after few hours of usage. I know that there are cooler fans inside the laptop but I wondered whether it is effective enough to cool this laptop. So I decided to buy a notebook cooler from Cool Master. There are many brands of cooler fans in the market – from the cheap and no frills type to the very expensive designer version. After going through the various cooler fans on the shelves, I decided on Cool Master.
This model that I had bought is called the Notebook U2 which is 14″ and can accommodate up to 17″ notebook. It is very light weight and is made of aluminum wire mesh. The exact dimension is 343 x 266 x 58.6mm and the weight is 725gm. It has 2 fans that are removable and adjustable to mount on any location within the aluminum wire mesh. The fan dimension is 80 x 80 x 10 mm. One good feature is that when you put the laptop on the wire mesh, it actually prop it up to an ergonomic angle so that it is now easily to type and view the screen on the notebook.
Another good feature is that you can actually remove the 2 fans; and thereafter placed the notebook within the secured slot and then secured it with a elastic belt which is provided. This means that you can carry your notebook and the cooler fan at the same time. Is the cooler fans effective to cool down my notebook? I felt that the wire mesh and the 2 cooler fans does help to dissipate the hot air quickly. This is especially good if you are using the notebook at room temperature in a hot tropical country where the heat can really intense.
The notebook cooler from Cool Master is a good product and is doing a good job in dissipating heat from notebook. It is very quiet when it is in operation. This cooler fan runs on power – there is a USB plug that is provided for you to plug it to the notebook. The USB plug provided by Cool Master also have a secondary USB slot provided – that means that it is giving back one USB slot for me to use it – really good.
There was one incident when I turned on my desktop PC and there was no display on my LCD monitor. The desktop was turned on and LED button on the PC was lighted up but the LCD monitor screen was blank. I proceed to check all the cables to make sure that it were firmly slotted into the respective slots at the back of my desktop. Then I checked the LCD monitor to make sure that it was working well. After that, I turned on the PC again and there was power but the PC was not booted up – there was the absence of the normal single beep sound.
I opened up the casing of the PC and then turn off and on the PC again. The desktop PC turned on, I saw the cooling fan moving and the power supply box was also functioning well. Everything seems to work well except that the PC did not boot up – again there was no beep sound. I have previously encountered this problem years ago on my old PC and the technician told me at that time that the memory card ( RAM ) was faulty. He replaced the RAM and the PC worked perfectly thereafter. My current desktop is using 4GB DDR2 memory – there are 2 memory cards in the slot.
What I did was to turn off the power on the desktop, and remove the 2 RAM cards from the slot. Remember to unhook the catch on the left and right side first before you can remove the RAM card. I took off the 2 RAM cards and then slot one of it in; then I turn on the PC – again there was no beep sound. I turned off the power of the desktop and remove the RAM card; then I slot the other RAM in and turn on the desktop again – again failed. Then I remembered that I still have a old RAM card from my previous old PC. Though this RAM card is not suitable for this current desktop; I wanted to try to see whether it can work.
Remember to turn off the power of the computer when you are putting in or taking out the memory cards. I put the old memory card into the slot and turned on the PC, there was a beep sound but there was no image on the LCD monitor. I turned off the power and turn it on again – again there was a clear beep sound but no image. So I took off the old memory card and then slot the two existing RAM cards into the slot again. I turned on the power and viola there was a clear beep sound; the Windows 7 icon appeared on my LCD screen; and the PC was back to normal again. What I was doing is simply to flash the memory module or reset the computer memory. So if you have an old PC, do remember to keep the RAM card; as you may need it in future to reset or flash the memory module in your desktop.
When your desktop PC have no display but there is power, do check the all the cables and power supply first before attempting to open up the PC. When you are opening up the casing of your PC, do remember to turn off the power before touching anything inside – remember safety is paramount.
Recently I have encountered a problem on my desktop PC. When I turned on the PC, the Windows 7 remains stagnant and refused to start up / boot. All that I saw on my LCD screen was the Windows 7 icon being frozen. I tried to restart my PC and also used the Windows repair option as provided in this operating system, but it did not work. I am no computer expert – in fact I am almost a complete idiot when it comes to repairing my desktop PC. My first thought was perhaps it was time to buy a new desktop PC – as this PC was around 2 years already. My desktop is a Intel 2 Core Quad with a 4 GB DDR2 memory – it is a very fast desktop and I could do many tasks simultaneously easily. So it would be such a waste simply to discard this desktop.
My next step was to called up a PC repair store and I told them the problem over the phone. The person told me that the charges to fix the problem was approximately US$200 and it could be up and going in about 4 hours – meaning that I could collect it on the same day. He mentioned that he would have to a diagnostic test on my desktop and most likely to replace my existing hard disk with a new one. The warranty period after the repair was one month. I felt that the repair cost quoted was expensive and was hoping to find another repair store which can do it at better rate.
While I was watching the TV in the evening, I suddenly recalled that I have a hard disk which I had removed from my previous old desktop PC. I took it out from my store room and saw that it was a Hitachi brand hard disk. I opened up my desktop and remove the current hard disk from the slot. Before removing it, I had to pulled out the 2 cables that were attached to the hard disk. It was quite difficult to pull out the hard disk from the steel slot as it was a tight fit – the trick is to do it slowly with a firm grip. After removing the hard disk, insert the new hard disk into the slot; again do it slowly and push it in with a firm grip. Thereafter reconnect the 2 cables to the new hard disk.
The next step is to insert the Windows 7 boot up disk into your CD slot and the Windows 7 would automatically prompt you to install the operating system into the new hard disk. If there is no prompt, just off the PC and then turn it on again. – remember the Windows 7 boot up disk should be in the CD slot. Just follow the instructions as given and install Windows 7 – it took about less than 30 minutes to install Windows 7 for my desktop PC.
Now my desktop PC is able to function normally again. I believe the cause of the problem ( in my case ) was that the hard disk was corrupted. I am not sure whether there are any other reasons that cause the Windows 7 unable to boot or start up; but if you have a spare hard disk on hand, perhaps you can try out this method. Remember the hard disk that you are going to replace need not be the same size (GB) as the existing one in your PC. In fact I used a lesser GB hard disk to replace the current one in my desktop and it still work perfectly. You can increase the memory size in your desktop later by buying a new hard disk later and adding it to your PC.
