I've got a pc which I'm using now that has served for a good 6 years now. Just this Friday I decided to give it a good thorough cleaning to get rid of accumulated dust inside the components.


Bought a compressed air can to blow them out, took them out and assemble them back, and to my dismay the pc won't boot up.


Specs :-

Asus P8P67 PRO

Intel i5 2500k

2GB x 4 Kingston DDR3 1333mhz RAM (8GB total)

MSI GTX 750 Ti


128GB M4 Crucial SSD



The DRAM LED on the motherboard stays solid red all the time when I have all 4 sticks RAM occupying the DIMM slots. I've tried clearing CMOS and push MemOK button with no positive results at all. So I tried one stick at a time and found that slots A2 & B2 is working; hence I'm able to seek for help in this forum. When I tried plugging the working RAM into slots A1 or B1, neither of them will boot the PC up. Oddly enough when I tried the remaining of my sticks with slots A2 & B2, they showed solid red DRAM led. Only my first two RAM sticks able to boot up using A2 & B2 slots.


What stumbles me is that if slots A2 & B2 is working fine, my 3rd and 4th RAM should be able to work on them. As it stands right now, I am not sure if the ones that are not working is DIMM slots or both DIMM slots and 3rd and 4th sticks is faulty.


I've tried reseating the CPU a few times with no success. Previously all my RAM sticks were working fine prior to the cleaning. So did I damage something or am I missing anything here?

Note that testing each module separately...then in pairs...then in multi-pairs...is the recommendation.

I can't even get my unused RAM sticks to boot up the PC using working DIMM slots. Does this mean the module is dead for good? I cannot believe that it would happen so sudden. It was working properly before the cleaning. Sigh.

i would recommend to unplug your pc from mains and disconnect your psu from your motherboard, remove your cmos battery and remove all your ram dimms


you have to remove those parts because sometimes the problem is with the static electricity


leave your pc for that way for some time (half an hour to a couple of hours) 


the time is needed in order your capacitors on the motherboard to fully discharged and for any left static electricity


reconnect everything and normally your pc will be booted


if you still have problem then maybe you have a hardware problem but this occur very seldom...


good luck

Make sure there isn't any gunk on the gold contacts of the RAM slots.
