2，64位win7频繁蓝屏看记录都是gdrvsys引起什么情况

蓝屏的种类有很多种，究其原因也十分复杂。不过想彻底解决蓝屏我有小小心得。出现蓝屏的原因往往集中在不兼容的硬件和驱动程序、有问题的软件、病毒等。请按如下方法排除解决：1、硬盘连线是否松动；无异常后，对硬盘进行查错处理；2、系统是否有病毒，建议安全模式下扫描杀毒； 3、把BIOS恢复出厂状态试试；4、装系统后硬件的驱动程序是否安装成功？ 5、最好先重装操作系统； 6、如重装系统后仍有问题，则极可能是硬件不兼容所致； 7、向商家或周围熟悉电脑的朋友咨询一下也好，或许他们会给予帮助； 8、祝你好运！望能帮到朋友你！

3，TPS40210芯片BP脚的功能是什么接了一个电容对地电容坏了电压就没有了

网上很方便查，5 Pin Configuration and FunctionsDGQ10-PinTop ViewDRC10-PinTop ViewPin FunctionsPINI/ODESCRIPTIONNAMENO.BP 9 O Regulator output pin. Connect a 1.0 μF bypass capacitor from this pin to GND. 稳压器输出引脚。在此引脚与GND之间连接一个1.0μF旁路电容。BP就是旁路（ByPass）的意思。一般是自举电容之类的。由于芯片内部制造电容电感很困难（制造半导体器件如晶体管却很容易），所以设计时把集成电路中需要接电容的地方用引脚引出来，在芯片外面接。所以越大的芯片引脚越多，四周放的电容也越多。COMP 4 O Error amplifier output. Connect control loop compensation network between COMP pin and FB pin. DIS/EN 3 I Disable pin. Pulling this pin high, places the part into a shutdown mode. Shutdown mode is characterized by a very low quiescent current. While in shutdown mode, the functionality of all blocks is disabled and the BP regulator is shut down. This pin has an internal 1 MΩ pull-down resistor to GND. Leaving this pin unconnected enables the device. FB 5 I Error amplifier inverting input. Connect a voltage divider from the output to this pin to set output voltage. Compensation network is connected between this pin and COMP. GDRV 8 O Connect the gate of the power N channel MOSFET to this pin. GND 6 - Device ground. ISNS 7 I Current sense pin. Connect an external current sensing resistor between this pin and GND. The voltage on this pin is used to provide current feedback in the control loop and detect an overcurrent condition. An overcurrent condition is declared when ISNS pin voltage exceeds the overcurrent threshold voltage, 150 mV typical. RC 1 I Switching frequency setting pin. Connect a resistor from RC pin to VDD of the IC power supply and a capacitor from RC to GND. SS 2 I Soft-start time programming pin. Connect capacitor from SS pin to GND to program converter soft-start time. This pin also functions as a timeout timer when the power supply is in an overcurrent condition. VDD 10 I System input voltage. Connect a local bypass capacitor from this pin to GND. Depending on the amount of required slope compensation, this pin can be connected to the converter output. See Application Informationsection for additional details.
