Graphics common troubleshooting

Common fault one: show no boot
Such fault general because graphics and motherboard bad contact or motherboard toshiba satellite a10 sp129 laptop cpu cooling fan slot have caused problems. For some integrated graphics motherboard, if memory Shared main memory, it is required to pay attention to the position of the memory bank, generally in the first memory bank slot should be inserted in a memory bank. Due to the graphics cause boot show no fault, after startup generally will be issued a long two short bumming (for AWARD BIOS for video card).

Restart, Windows 98 system normal mode delete graphics driver program, and then restart the computer toshiba satellite a15 s127 laptop cpu cooling fan. Also don't enter the safe mode, in pure DOS (henan emba) environment, editing SYSTEM. The INI file, will display. DRV = pnpdrver to display. DRV = VGA. DRV, save exit, and then in the Windows update driver.

Common fault 4: system halted
Such fault appears more commonly found in main board and the graphics card not compatible or motherboard and graphics bad contact; graphics
And other expansion card not compatible can also cause system halted.

Common fault five: screen abnormal noise point or design
This kind of failure is usually due to the graphics memory problems or graphics and motherboard bad contact cause. Need to clear clean graphics goldfinger site or replace graphics.

Common fault 6: graphics driver program lost
Video card driver loaded, running after a period of time the toshiba satellite a15 s1292 laptop cpu cooling fan drivers are automatically lost, this kind of fault is generally in graphics by poor quality or graphics and motherboard not compatible, make graphics temperature is too high, resulting in system operation instability or appear crash, the only change video card.

In addition, there is a kind of special circumstances, before can be loaded with graphics driver program, but in graphics driver program load into, into the Windows there was a crash. Replaceable other types of graphics in load the driver, insert the old graphics resolved. If it can't solve the fault, then explaining the registry fault, to the registry in henan from toshiba satellite a15 s157 laptop cpu cooling fan an line recovery or reinstall the operating system can.
