 Post subject: Acer Aspite T120E Display keeps going to vertical lines

I Use my Acer Aspire T120E to monitor and record my CCTV. It was all working well but now it won't record as the cctv image freezes when I press record, if I stop recording it will monitor the CCTV. However, after an hour the whole display (tft) goes to coloured vertical lines and I have to reboor the system to start again. Is this a problem with the graphics card and can it easily be solved. i was thinking of buying a RADEON™ HD 4770 GRAPHICS CARD as I beleive I can just plug it in a pci slot. Would this solve the problem? ANy advice would be much appreciated.

Make sure all your vents are dust-free. Also consider getting a decent laptop cooler. My g/f has an Aspire with the same issue. More than likely the GPU overheating as it's only cooled by a small heatsink with a tiny heatpipe that connects to the CPU heatsink. Kind of a shoddy design actually.

Hi, Thanls for your reply. My Aspire is a tower PC which is in a cool environment, I did 'have the back off' and extract all the dust possible without damaging it but it still does the vertical line thing - do you think a new video card would solve it?

It would, but it might not be necessary. Is there an actual fan on the video card or just a heatsink???

Well, does it seem like it's not spinning, spinning slowly, or making an unusual noise.
