CMOS checksum error, 0x0000008E, 0x000000D1, all happened in consecutive days

Recently, I don't know why, but my computer started to literally piss me off.
It first kept me manually rebooting it then until I've done it a few times, it can work stably. (no rebooting, no bsod, worked fine)
This is still happening. Then I went into safemode, and this time the computer didn't reboot. I couldn't find out the exact reason for this happening because there is thousands of reasonable answers for this.
After a few days, CMOS checksum error showed up. I googled it, and found that it was because either battery has not enough energy or not enough RAM or BIOS error. I went into BIOS and resetted it to default.
Later, STOP: 0x0000008E appeared. I googled it, apperantly I got affected by some rootkit called pe386, but I did nothing, and error didn't happened again.
Today, I'm getting another BSOD. I copied down some of the techincal details:
DRIVER IRQL NOT LESS OR EQUAL
STOP: 0x000000D1 (0xB7E45320, 0x0000001E, 0x00000008, 0xB7E45320)
NDIS.sys Address B7E45320 base at B7E19500 Datestamp 48025D03
NDIS.sys Address B7E45320 base at B7E19500 Datestamp 48025D03
Like always, I googled it and found thousands of solutions for "0x000000D1 ndis.sys"
I want to finish it once and for all. Can any kind souls help?

I'm chinese, so if my English is bad and you can't understand something, please reply to this thread, I'll try to explain what I'm saying
