[SOLVED] PC Freeze when left idle

[Giorici]

When i left my pc idle for some time, like more than 5 minutes it freezes, and i can't do nothing, but to restart.
I've searched on all sites i've found and still nothing.
Specs:
i5 3470 3.2ghz
rx 550
8gb ram
500gb hdd
450W psu

You use a lot of generic no-name parts. listing part numbers would help - motherboard, memory, power supply.

Based on the info you've given, not much to guess.
You can try:
1. Disable advanced power management in BIOS
or
2. Reinstall the power management drivers for your board
or
3. Disable sleep and idle timers in Control Panel
