I had this compaq laptop since I was in my Eighth stabdard and it was an exciting feeling that time to have a laptop at home and that of hp brand. Yes, compaq is another brand of HP. It worked well and smoothly for like 4 years with 206GB storage and 1GB RAM. But I don't know what happened to it and its screen started to flicker at the bottom of taskbar. I thought it is because I pressed the screen and it disturbed the screen bit when I searched it on google, I was surprised to know that it happens usually in compaq CQ40. Then I tried to change the screen but because it was LCD display, I hardly could find it in the market and after it was changed my laptop stopped working and it could not get started so the only thing I did was change the laptop.
