Graphics display problem and what could it be?

  Audio~~Chip 14:10 10 Aug 2009


after 8 months of using my machine the picture has started going with all funny lines and then eventually the screen goes like a negative film incorrectly developed look and all magenta looking
the mouse and everything then freezes up.

Then either shuts down and reboots but most times the screen goes blank but the tft itself doesnt go into a standby.

All this happens after about 30mins+ when things have warmed up I can only think its either the PCi EXpress XFX 256MB 7200GS card or the Samsung 500GB Sata HDD throwing and wobbler. So would a HDD cause this ? I am between HDD or Graphics Card, I have tested the PSU, Screen, Memory and HDD.

The HDD does show 1 bad sector but I feel this maybe false not sure

Help again please

best bet is to have a paid for anti virus like avg 8.5 or norton seems like you might have a crawler in your system if all you got is free anti spyware stuff its not good enough PLEASE DO NOT DOWN LOAD ANTIVIRUS 2009 it is a VIRUS

Could be heat affecting the system or the PSU is on the blink (I once had similar display symptoms with a new ATi card, which was due to the PSU's wattage being insufficient).

The PSU is rated high enough, more than enough 600w. Heat on the Graphics card is a possibitly as its fanless and have seen thing around other forums they get hot. Thanks

No spyware or bugs in the system, Kaspersky is sorting that out fine. 15:22 10 Aug 2009

LCD and/or the video card could be faulty.

Hope this helps!

Have you checked the connections from your system to the monitor for firmness and also, if necessary, updated the graphics drivers?

This looks very much like a thermal issue...[QUOTE]All this happens after about 30mins+ when things have warmed up [END QUOTE]
If you are using a generic PSU ...even though its rated @ may not be supplying a stable voltage...If there is a build up of heat in your case from other components ...and plus the fact that your card is passive cooled...all this may be adding up to the "shut down" after the 30 mins you state..If you can remove the side of your case and make sure you have no pets or children nearby who could inadvertantly get close to the fans and PSU etc:!!!! you can find that the extra airflow may well allow you to run your machine longer before a shutdown occurs.Be very careful if you do this!!! ..but its a good way to find if the issue is down to overheating of the case internals !If your machine runs longer prior to shutdown..Its highly likely that its a thermal fault!

  Audio~~Chip 16:45 10 Aug 2009 Tried on a different TFT same problems.

Stuartli: as PcTestCard,com tried other TFT

sonyboy: Fans running fine, clean inside everywhere but the PSU is a OEM PSU from Going to borrow a PCi-Express Card tongiht of a friend so thats a start to test things out.

Thanks all so far, will post back later when I have tried it with the other card.

I found nVidia PhysX installed as well as Nvidia drivers in the add/remove programmes list.

Can someone tell me if this is donwloaded withe the drivers from website by default or is it a extra download please. If it is extra then I know who to blame. As I think this may be the problem. I removed this and everything seems to be running fine!

its from nvidia and makes effects look better in games but it will not work on your card as its old.
