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.
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?
