My PC suddenly feels very laggy. Sometimes when I type, I suddenly get many duplicate characters. When I go into console (Ctrl+Alt+F2) I see afew messages abt NMI: IOCK error (debug interrupt?) for reason 60 on CPU 0 popping out. The reason number might be different. I am getting: dmesg output. This was on Arch Linux. But on Windows 7, I gotten 3 BSOD's by now at different times about Hardware Malfunction, NMI: Channel Check / IOCHK
Its a Intel Core i3 2100 and ASUS H77M MB. I originally thought it was a SSD fault (prev post) ... Does this likely confirm CPU is faulty? What can I do? Will trying to resit the CPU in the MB help?
I think its useful to understand the cause too. since its a self built system. So I can avoid making same mistakes again? The CPU was in use for probably >1 years? The MB was replaced probably just ~6mths (guessing) due to mistake in flashing BIOS. No other major changes in hardware apart from that. CPU temps looks fine typically <40 degrees from BIOS. I noted that BIOS POST works, does this eliminate problems with CPU/MB? Its after POST, it gets stuck at blinking cursor. I tried booting from a bootable USB too. If the HDD is stuck, then USB is likely going to encounter the sme problem too.
UPDATE
I noticed that if I can get to Syslinux bootloader, after selecting an entry, I usually get Parity Error. I tried removing one RAM at a time, results are inconsistent, sometimes, I will only get a blinking cursor after POST (thus no syslinux nor partity error at all). I am thinking I might need to change some components soon. But I was hoping to isolate the problem so I dont replace working parts if possible.

I originally thought it was a SSD fault (prev post) ... Does this likely confirm CPU is faulty? What can I do? Will trying to resit the CPU in the MB help?
I think its useful to understand the cause too. since its a self built system. So I can avoid making same mistakes again? The CPU was in use for probably >1 years? The MB was replaced probably just ~6mths (guessing) due to mistake in flashing BIOS. No other major changes in hardware apart from that. CPU temps looks fine typically <40 degrees from BIOS. I noted that BIOS POST works, does this eliminate problems with CPU/MB? Its after POST, it gets stuck at blinking cursor. I tried booting from a bootable USB too. If the HDD is stuck, then USB is likely going to encounter the sme problem too.
UPDATE
I noticed that if I can get to Syslinux bootloader, after selecting an entry, I usually get Parity Error. I tried removing one RAM at a time, results are inconsistent, sometimes, I will only get a blinking cursor after POST (thus no syslinux nor partity error at all). I am thinking I might need to change some components soon. But I was hoping to isolate the problem so I dont replace working parts if possible.
