I downloaded several add ons presumably to improve my internet browsing. But then, my laptop slowed down. Then lately, a flashing notice appeared that another program is attempting to replace myspace as home page browser or something like that. Since then, my monitor kept blinking every few seconds.

Yeah, I guess so, but not as fast is it was when it was new. I was told it is because of the excessive files stored and that would be my next question.

How can I prevent the automatic storage of downloaded files. For example, when I download any data sent thru mail and hit save to documents, it would be automatically on my desktop, on recently changed and later, on documents. I do a lot of file deletes manually even those in the recycle bin.

I am not adept with computer usage. Is there an easy way to clean up and defrag, manually?

By the way, my laptop's monitor is again back to blinking. I have done full scans using Eset's and Microsoft Security essentials. Both results says "no threats found." I have tried also, removing the battery. Still blilnks.

that means it is set to auto run on aug 4

if you want to do a manual defrag click on defrag now or run it from system tools by clicking on the start button/programs accessories/system tools /defrag

you will not find anything on the backlight in windows except the brighten and darken keys on the k/b

to check the b/light you shine a torch onto the screen

Hello!

I raised this topic about my laptop blinking a year ago. Because I had to use it continually and since there was an improvement, I did not bother to have it really checked or repaired. I brought it to computer shops but technicians always tell me that the blinking is caused by either LCD or Flex defect which I doubted.

Last year, I mentioned possible reasons of the blinking to downloading add-ons. Then I recall that one time, my backpack where the laptop was in was bumped by another plane passenger.

My laptop was originally operating on windows vista home basic then on May 2011, I had it changed to Windows 7 ultimate. On June 19, 2011, I left my laptop to an office mate when I travelled. When I got back on July 10, I found that the laptop had gone worse. The blinking was almost continuous. I did a system restore back to June 12, 2011. The blinking got corrected to very tolerable frequency. Then there was a file which I could not open and Adobe flash player popped out saying that I should update. I did so. A few minutes later, I noticed that several icons on my desktop, google chrome, mozilla, windows office and others changed to the adobe reader icon. I tried but could not open them with adobe dialog box saying it could not open because it is not supported. I could not open the programs whose icons were changed with the adobe icon. I could not connect to the internet.

I opened the control panel in an attempt to system restore again. This time I could not open system restore also.

I brought the laptop to a computer shop and again technicians told me that it is a defective LCD causing the blinking. I did not let them change the LCD. I had the laptop reformatted just so I could open the programs and can connect to the internet.

My laptop is Compaq Presario CQ40. Somebody please tell me the real cause for the blinking.

Thanks.
