I had to factory reset my pc
We a sorry for the troubles you got into. But keep in mind that very many gamers use HiAlgo with many games including CS:GO.
You can search this forum, or Youtube or the internet in general. It is unlikely that HiAlgo itself caused this problem. Maybe its interaction with some other program? Now, after the factor reset, we will never know.
What you can do is to try HiAlgo on the freshly reset computer: if it crashes again, you can reset again, without losing much. If it works, then you will be sure that HiAlgo is safe.
