我需要专家的帮助。最近我的一个朋友带来了备用零件并帮我组装了一台电脑。电脑的规格如下：
Casing: Aerocool vs92 gaming
Processor: core i7 3.4-3.9GHz 8mb cache LGA1155
Mainboard: msi b75 MA-G43 professional
Memory: Kingston 4GB DDR3 1333
HARDDISK: TOSHIBA 500GB SATA 7200 RPM
GRAPHICS CARD: msi HD 6450 2GB FULL HD HDMI
WINDOWS 7 ULTIMATE 64 bit
我已将 minidump 文件上传至 dropbox，并发布了以下链接：https://www.dropbox.com/s/d1i40f618m1kglc/Minidump.rar
实际上，电脑重新启动时出现 bccode 错误代码 2b 和 a。重新安装显卡驱动程序后，电脑重新启动时出现错误 bccode 117、1a、4e、d1 和 a。
有人能帮我了解发生了什么事以及如何解决这个问题吗？我应该更换显卡吗？我应该更换任何部分来解决这个问题吗？我需要专家的帮助。请帮帮我。

IRQL_NOT_LESS_OR_EQUAL (a)
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high. This is usually
caused by drivers using improper addresses.
If a kernel debugger is available get the stack backtrace.
Arguments:
Arg1: fffffa86017ecff0, memory referenced
Arg2: 0000000000000002, IRQL
Arg3: 0000000000000001, bitfield :
bit 0 : value 0 = read operation, 1 = write operation
bit 3 : value 0 = not an execute operation, 1 = execute operation (only on chips which support this level of status)
Arg4: fffff80002ce835f, address which referenced memory

MEMORY_MANAGEMENT (1a)
# Any other values for parameter 1 must be individually examined.
Arguments:
Arg1: 0000000000041790, A page table page has been corrupted. On a 64 bit OS, parameter 2
contains the address of the PFN for the corrupted page table page.
On a 32 bit OS, parameter 2 contains a pointer to the number of used
PTEs, and parameter 3 contains the number of used PTEs.

请下载memtest86+，从 ISO 刻录新的可启动 CD（如果可能，请使用 CD-RW）（下载并使用图像烧录要执行此操作或双击 Windows 7 中的 ISO），请重新启动 PC 并扫描 RAM 4-5 小时以查找错误。如果 memtest86+ 检测到错误，请测试每个模块并更换有故障的 RAM。
如果memtest没有错误，请下载CPU-Z，查看内存和 SPD 选项卡，并验证当前 RAM 速度和时序是否与您在 SPD 选项卡中看到的值匹配。如果您的 RAM 以 CR（命令速率）1T 运行，请在 BIOS 中将该值更改为 2T。
