hey guys today I cleaned my cpu and gpu and for the first time ever in 5 and half years of owning it this happens, I've cleaned my pc before and this never occurred. I tried resetting the cmos and it didn't work and one thing to note is that the gpu isn't really fastened, I mean if it moves unlike the ram for example. the pc in question is a prebuilt hp omen 870-57ng :
gtx 1080
i7 6700k
32 gb ram
please guys help me I can't afford to spend a lot of money for a new pc, I have to fix it.
