computer screen keeps blinking

by edisonp / May 4, 2008 8:44 AM PDT

My computer (laptop) screen keeps blinking a few minutes after turning it on. Eventually, it shows glitches and somewhat freezes. Before, I'd just restart the computer and it would work fine. But now the monitor blinks and eventually doesn't come back up. And then I have no choice but to unplug the computer. Please, if anyone can help me I'd really appreciate it. Thanks.

My guesses are
maybe I need to clean the fan (with an air compressor?)
it could be a virus

re-install the Operating System, whatever that version might be?

Did you also download the driver from here and install them in this order?

Desktop System Software or Notebook System Software
Chipset or SMBus driver
Processor Driver (if applicable)
Video
Audio (sound)
Input Drivers (keyboard/mouse)
Modem
Network Card

Heat will cause a variety of problems. We recently did have a dying screen on a laptop. This was confirmed by plugging into a regular LCD monitor. The laptop ran fine but the screen looked like garbage. I replaced the inverter card but that didn't work. A new screen did the job.

when the voltage gets high enough the capacitance touch switch for the monitor power passes current. After it discharges, the screen goes black until it charges up again. I had the same problem with a x2gen bargain monitor. My fix was to physically crush the frame around the switch driving the faces closer together.

For a laptop, there is probably a switch for the computer to sense when the laptop is closed. I propose it is probably the same problem. They can be sensitive.

to my laptop. It seems to have just started doing that one day and was getting worse everytime I use it.

I probably use our Plasma TV, though, I just need a cable.

One other thought and hope this isn't the case

There have been some IBM models where the GPU's surface solder connections begin to crack and cause the screen to blank out. Pressing on the right spot on the keyboard re-makes the connections and the screen comes back. Try pushing down lightly on varies areas of the keyboard when this happens. If you can make it come and go, you may have a detaching GPU.
