I owned insperion 3542 laptop. From the first my processor fan is not working correctly. I have notice it later and requested to c. care to replace it and they do so. But from the beginning my screen round the border is blinking white when am seeing video or playing game even sometime from the windows start screen. As then the fan is not working, the machine is overheated so am thinking that this is the cause. But now my fan is all right but my screen is not. I can't play any video game smoothly(even a non graphic requirement one), the video is halted and sometime the screen is slowly getting white and at a sudden it back and it is continued to full day. I have installed all driver, downloaded from dell official website. Please tell me what is the problem. My laptop diagnosis is saying everything is all right even i have tasted dell online diagnosis and it is also indicated all are ok!!!
