I have an Geforce 4 Ti4200 128mb card.
I recently decided to disconnect my extra case fan at the back.
It has worked normally for a few weeks.
Yesterday when I turned it on, it got some way towards loading windows (I saw it at the grub bootloader stage) and the went black. I reset it, And carried on using the pc.
Then I loaded up Commanche 4, and after a while the screen started getting garbled - most of it was there, but in places pixels from other parts of the screen were being displayed. Then the system froze.
I opened the case and it was rather hot inside, so I reconnected the case fan and let it cool.
Today the same thing happened, it just lasted much longer before it started getting garbled. The air exiting the back of the case is still fairly cool.
I have preiously modified the airflow slightly by removing two pci covers to allow cool air in at the back by the graphics fan. Placing my hand over these I can feel an inflow of cool air.
Is my problem a cooling one, or is my graphics card just dying?
I've reinstalled drivers and it's still the same.
