Small can of air duster got knocked off shelf and onto my computer and it froze. This has happened sometimes when I slap the top of the computer because of the fan noise sometimes but I always turn it off and once reboot it’s all good. This time was very different.

At first it wouldn’t even boot up, would make a very weird loud grinding noise then shut off then loop. Waited few min and tried again and it booted but no screen, motherboard light indicators flashing back and forth between cpu and memory. Did a google search and someone else had same problem recommended ram in slots 1 and 2. Did it and it thankfully worked.. so everything running fine for now.

I’m just confused what happened and why slapping the top of the computer or something falling on it, sometimes only, will cause the pc to freeze and need reboot. My cat will jump on it sometimes and nothing happens and I’m sure he weighs more than air blaster can. Nearly empty btw.

RAM Slots: 1 2 3 4.
Had them in 1 and 3 for at least a year and now moved them into 1 and 2. CPU temps are actually a bit cooler too, 2-3c

Another thing that may help is that I have had a very bad experience with delidding my 7700k so I wonder if that would have any side of effects on this if done improperly, like the freezing sometimes etc

MB: Z270 GAMING M3
RAM: Corsair Vengeance LPX 16GB (2x8GB) DDR4 DRAM 3200MHz
 
reset the cmos battery.

pull the powercable out of the wall
open the case
locate the cmos battery (button/round battery u put in watched) probably in the middle of the mobo or slightly above your pcie slot.
and than click that thing out

hold the powerutton 30s

wait 2min

put the thing back in and try to boot the pc.

hm what do you think that connection would be? everything seems to be plugged into the motherboard very securely and nothing is loose or broken. where should I start? are you thinking it may be the cpu cooler/fan? also I just find it so odd everything is working fine for around a year and then an empty blaster can falls on top and requires ram stick to be stuck into slots 1 & 2 instead of 1 & 3. what could possibly even cause something like this?

It was the first time hearing it, not sure what that was.. but weird thing is it didn't start doing that until after restarting the computer. The empty air duster can fell on top, froze the computer, restarted it and that was when it did the loud grinding then immediately shut off and looped. Not really sure what fixed it other than a few minutes just being turned off completely.

Some scary weird stuff going on which is why I'm assuming nobody here can unfortunately expand on whats going on as it's just a totally odd problem I guess. The memory slots must be a motherboard issue.. probably going to avoid MSI from now on.
