Keyboard issue: spam letter k

Hello,

Hello everyone and thank you all for the support you can provide daily, I mean these forums are really gems for solving computer troubles. However, after searching for a long time, I haven't found a solution to my problem; at least not a definitive one.

Here's the issue

I have an HP Pavilion g7 (I know it’s not the best but it was cheap for what I needed) and on this computer, I have an annoying problem that I've managed to workaround but let's say I've just moved the problem

In fact, I have the "k" key that is spamming constantly, so my solution was to first disassemble the keyboard and then clean it, finally using the software SharpKeys to send my "k" to replace the exponent "2". But I think in the background the k continues to spam, I notice this especially when I launch the console of certain games.
So, it’s clear that there’s no more direct spam issue, but sometimes I think it’s the cause of the computer overheating, it takes a long time to launch an application or even when it’s really hot and I try to restart, I get a series of BIOS beeps (not a recognizable beep kind, rather a long series of beeps that prevents booting)

So my diagnosis:
I think that since I’ve put an i5 in the PC, it heats up quickly and that causes a slight malfunction in my keyboard and it also tends to block the pad, but if I plug in a USB mouse, there’s no problem

Now I would like to know if you think I can improve my condition, hehehe, by removing the k key?

Thank you in advance
