Chosen Solution
Okay so a long time ago i had a clean-up on pc(Bcz of freezing,lag e.t.c). pc was lagging hard bzc of cooler so i decided to remove all of these parts of computer and cleaned up. When i done with these clean up i put pc part in right place so something happend my 1st ram slot was not working (BTW it was working fine untill that). Definitly checked both ram slot (2x2gb ram each side). and 1st ram slot was dead AF. tried everything changing ram (But both ram was quite well working), cleaning slots or even what i could. I searched on net but nothing was that good for work with. IK i should take to local shop for fix but i want to fix by self so any ideas that can help me to fix this problem ?
Hi @meliodas , What is the make and model number of the device in question? Presumably you cleaned the RAM slots with the power disconnected from the device? Did you clean the RAM slots? If so was it with an electronic contact cleaner spray? (although RAM slot usually don’t need cleaning if the module is working OK) Have you checked the slot, using a strong light and a magnifying glass, to ensure that you haven’t damaged any of the connectors? (Do this with the power disconnected). Check around the RAM slot in question that you haven’t accidentally removed any components from the systemboard due to “cleaning”. If you can’t see anything obvious then perhaps you may have damaged a component somehow: either electrically if the power wasn’t removed during cleaning. If it is a laptop then there is power still on the systemboard as long as the battery is installed. It doesn’t have to be switched on for this, or mechanically by the cleaning action.
