[SOLVED] Optiplex 3020 freezes randomly

[tekboi21]

Optiplex 3020 powers on normally but freezes after about 45 min there is no bsod or reboot it just stays frozen until hard reset. the issue seems to be the psu or mobo. any idea which one?

It's a SFF Dell PC. Specs?

First check the HDD status using speccy, HWinfo. if its 'good', then make sure correct drivers are installed.
