Today I accidentally filled my RAM by running Photoshop multiple times. Right when the first tab opened, it said it was out of memory and my PC stopped working. There was no BSOD—just like unplugging it. When I tried to restart, the BIOS screen appeared but didn’t show up. I had to press the reset button on my motherboard (using a screwdriver to connect the pins) and everything worked again. What actually happened? I think my RAM or cache was overloaded.
Reset the CMOS settings. Refer to your motherboard manual for instructions on how and where.
Manual? I didn't hear that for a while. I looked and my settings and time remain unchanged, no indication that the CMOS was cleared...
Machine is functioning correctly once more? If not fully, RAM overclocking is just inconsistent—either reinstall RAM or reset all BIOS configurations, or erase the CMOS.
Due to your forum profile, maybe the issue isn't about learning from the case. The main point is the OC was unstable. Edit: It seems you didn't perform an OC, just restarted the program ten times in a row. That could explain why the machine stopped working.
