[SOLVED] how to prevent hdd from corrupting if there is a sudden shutdown or sudden lights out?

[using google in BSOD]

it's kinda pissing to wait around 1 minute or more just because a sudden lights out or sudden shut down due to heat or psu problems at the startup in the windows 10 logo screen. and i still don't know how to fix it.

Sudden power outage is handled by a UPS. Allows graceful shutdown.
Shut down due to "heat" is solved by fixing the heat issue and airflow.
Shut down due to the PSU is probably solved by getting a better PSU.

is it safe to open the case's side panel while it's running?
will it make the air goes in and out better or will it fill the pc with dust instead?

Yes, yes and yes.
It's safe. It will allow better air influx. It will also allow dust to get into pc easily.

If you have electrical supply issues, then a UPS will let you ride through such outages.
The battery capability may need to only last you 5 minutes so you can gracefully shut down.

As it is now, there is a possibility that a disk segment may not get properly updated if the failure occurs at a critical point in the update process. One thing you can do is to disable disk write cacheing. You will pay a performance hit for that.

You can also run chkdsk which will scan for missing links and correct them.

I think it is never wise to handle a pc while it is running.
But, if a case side is easy to open, your risk is minimal.
If you are having heat issues, take the covers off before you test.
If that resolves the issue, look to case cooling solutions.
I would not worry about dust for a one time test.
Longer term, you want good front air intake that is filtered.
What is the make/model of your case?
What do you have inside that needs to be cooled?
What is your graphics card and cpu cooler?
