some of the better motherboards have protection logic. they will reset the CPU if the graphic card pulls too much current directly from the motherboard graphics slot. it happens if the GPU gets hot or you forget to connect a supplemental power connector from the PSU to the GPU. if you have a modular supply make sure you connect the power cable to the correct rail of the psu. cheaper multi rail psu designs might have different specs for each connection.
cheap motherboards will just let your graphics card and motherboard slot burn and catch fire.
gpu tweak tools can push the power requirements up to the point where the motherboard logic triggers a reset of the cpu. remove overclock tweak programs.

450 Watt or greater power supply with a minimum of 24 Amp on the +12 volt rail.****
your psu provides 37.4A for your 12 volt rail. should be ok.
I saw your note about the dust, I would think it could have caused over heating.
(assuming the supplemental power connector is properly connected and is providing proper power.
Finished cleaning it! Most of the dust was settled on the heatsink, not on the fan. I'll test it in a while
PS: even when it was dirty, the GPU worked in a nother computer. My friends psu is a Cx450M
I tried, but the pc keeps on rebooting
My psu is NOT modular, the pcie cord was connected and the gpu well seated, the temps were low, for as long as it stayed on, around 40ºC idle ( I live in a hot place).
Also, I do not have any kind of overclock.
Maybe the pcie slot could be the problem?
