So I have been experiencing this Dvi no signal crash where my monitor just suddenly have a 1 second loop sound (When I say loop sound i mean by the sound when your PC crashes, the berrrrrrrrrrrrrrrrrrrrr sound) blacked out and says Dvi no signal then the sound comes back ( not the berrr sound but the real in game sound) Then after like 5 second it has the berrr crash sound. One short solution I founded was taking the Ram out, switch their spot and restart my PC, this only solve it for a short term, like a week then it crashes again. The crash doesn't only appear when gaming, it appears when browsing, watching videos and etc. Im not sure if this is a software/motherboard/CPU/GPU/Ram problem, my estimation is the ram consider the fix has relation with the ram but I need help from the community because this crash has happen very frequently.

I have already run memtest, there is no problem. about the temperature, it crashes no matter what temperature, it crashes when the ram is cool, does the same when the ram is hot. It might not be the ram, im not clear but I founded out that when it crashes, the Numlock LED indicator turns off so that might mean the pc is already off but power is still on...

I have also founded out that the pc would say DVI no signal on startup and the PC fan would spin really fast and extremely loud, I havent figure out which fan is it but I think it might have something to do with it.
