Hacking Screen goes back during a game's loading sometimes on PSP 3000

[Windows_10_User]

Sometimes, when playing PSP ISOs, my PSP 3000 goes black and I have no choice but to turn it off (and I have to take the battery to do it since if exiting PSP ISOs using the "PS" button, the console freezes). I have 6.61 PRO-C with Infinity installed and this also happened with other PSPs.

EDIT: Sorry for the typo in the title.

I bought an used PSP, installed ARK-4, then Infinity and finally made a full flash install so that I can boot ARK-4 without a Memory Stick/microSD card inserted on the console (or with a different one). Sometimes, this PSP also goes black when playing PSP ISOs and I have no choice but to turn it off again (and I still have to take the battery to do it since if exiting the PSP ISOs using the "PS" button, the console still freezes).

EDIT: I installed ARK-5 on the PSP. To do it, I used Chronoswitch Downgrader to install OFW 6.61 on the PSP, downloaded PSP's FasterARK (the full version), copied the "CustomIPL", "FasterARK" and "ARK_01234" folders to the PSP's microSD card, ran "FASTer ARK", ran "cIPL Flasher" (to make ARK-5 permanent) and then deleted "FASTer ARK" and "cIPL Flasher" from the PSP's microSD card.
