Fujitsu Lifebook P727 laptop review
The following I have posted previously but new thoughts have caused me to seek further opinions.
One of my flock's display gives strange columns and lines not unlike a broad sheet newspaper with the proper display showing under it.
So far I have assumed this to be a hardware problem
[Graphics/video card] and this gave rise to another string of issues, which the machines owner has yet to address[buy new card or computer]
But now I wonder could this strangeness be caused by an external agency- a virus/malware/Trojan what have you?
What you all think?
As you hint, strange coloured lines in columns may also be caused by graphics card memory corruption, this in turn may be caused by the card not being seated properly. You could try re-seating the card before going the software route.
It may also be worth checking the cooling fan on the card for cleanliness. They suffer from dust/fluff as much as the CPU and other coolers.
If you believe that a piece of malware has got onto the PC, you should be able to confirm this by running the AV and several others (Spybot S&D, Spyware Terminator, Defender, A2 or similar). It can do no harm to check anyway. If you feel strongly that it is malware but are unable to shift or confirm it, an online scan (such as Housecall click here) is a good option.
I will look at those and consider the driver issue.
The card reseaigng and cleanup has been carried out - no affect.
The alternative monitor/or even onboard graphics proved to be a no no because the onboard socket appears to be non standard 2 row whilst the supplied documentation shows standard 3row socket [To morrow I will photo this as it most strange and will post the image] the connecting between monitor and card is HDMI.
I wanted at first to bring it home to set up on my KV switch but the non standard socketry has blocked that one.
A possible cause is the need for a higher wattage PSU.
As mentioned previously my investigations were not helped because the MoBo appears to be an oddball, so I could not access the on board video- to prove something although Everest Home said it was there- there was no socket.
The illustration shows Top a clip from spec sheet
showing normal socket.
Centre the actual backplane showing no socket
Bottom - the graphics card
This is for interest only.
