It's already been into the shop a few times because of the error, resulting in some hardware being replaced. Power supply the first time, RAM the second. \nThe problems only occur while I am doing something that makes the GPU work\nsuch as video games or Corel Painter 12.\n\n[I]If anyone would like to have a shot at diagnosing the issue regarding the errors I'd be happy to accept any offered advice.[/I]\n\n[U]System Specifications:[/U]\n-Purchased September 2009\n-Link to Detailed specs @youfindit.ca/acer/notebooks/1019004826\n\nGateway FX 2009\nGateway Godzilla N-10 motherboard.\nIntel core 2 Quad Processor Q9000 ((2.0 ghz))\nNividia GeForce GTX 260m (( 1 gig on board ram))\n4GB Samsung DDR3 Memory\n\n[U][I]Errors & The games that cause them:[/I][/U]\n\n- Began occurring in February 2010\n\n- Never Winter Nights2 ~ 2008\n- Never Winter Nights1 ~ 2002\n- Civilizations 5 ~ 2010\n- Civilizations 3 ~ 2001\n- WarCraft 3 ~ 2003\n\n(( Time out detection recovery is firing))\n\nNividia GeForce Driver has stopped responding and has recovered.\n- Notification after screen flickers black\n- Happens repeatedly whenever the GPU is engaged\n[B]- Happens [U]RARELY[/U] when my computer is unplugged from the wall[/B]\n- Repeated Driver resets lead to BSOD (( nvlkddmkm.sys is the file listed as causing the crash))\n\n[U]Other issues:[/U]\n-intermittently the 2.0USB ports & CD drive will not work\n-fans are not running as loud as they normally do but heat levels still look safe.\n\n[U]What I have already attempted:[/U]\n- Turn off Windows Vista Aero and animations\n- Updated all Graphics drivers\n- Clocked back Graphic drivers\n- Upgraded to Windows 7\n- Upgraded Drivers\n- Clocked back Drivers ((seems to work better than the current one))\n- replaced/expanded nvldmkm.sys\n- Replaced RAM\n- Clean Reinstall of Windows 7 ((boot from cd))\n- Turned off Windows 7 Aero and animations\n- Updated all Graphics drivers\n- Clocked back Graphic drivers\n\n[U]What I think?[/U]\n- It's a hardware issue\n- My graphics card is biting the dust\nThe first time I had my computer repaired\nThe manufacturer replaced the power supply and it seemed to Temporarily solve the errors, they started occurring again in June 2010\n\nThe most recent time I have brought my computer into be fixed was a few months ago, The tech who helped me at the counter suggested that I could have damaged the hardware of my computer unintentionally through the use of XAMPP while I am developing PHP. \n\n[U]What I use Xampp for:[/U]\n- Basic PHP (( I'm just starting object oriented now))\n- Sqlite ((still working with small databases))\n- Started using it in September 2010\n- errors NEVER occur while I am developing\n\nThere's also a few other quirks with the machine, It struggles to run CDs and on occasion my usb slots wont work untill I restart my computer.
