I had to add nolapic to boot. Now, It doesn't show all CPU cores?

I have old  Samsung NT300E5X notebook. After installing Arch, It randomly freezed and sometime didn't boot. By which, I ended up adding nolapic to the kernel boot parameters after quiet splash. Luckily, it solves the freezing problems.

Now, I found, nolapic restricts the processor to using only 1 core which ultimately become true in my case. I have tried other boot parameters also but the freezing issue didn't solve.

System Information:
- Processor - Intel® Pentium(R) CPU B960 @ 2.20GHz * 2
- Graphics -Intel® HD Graphics 2000 (SMB GT1)

Result:
- Before adding nolapic : 2 CPU core
- After adding nolapic : 1 CPU core

My questions are,

- How can I get back my 1 CPU core with nolapic ?
- Are there any other way to solve this without using nolapic?
