Optiplex 3050 SFF ram problem

Greetings

I need some suggestions.

After turning it on at first and testing it worked fine. Then I decided to clean it and reapply thermal paste. Next it refused to boot and fan spinning loudly. It turns out that now only dimm slot 2 works. I tested both modules the only work in on dimm slot. Can this be fixed? I tried blowing dust out of it using alchohol.

Could it be that the cpu was damaged somehow?

thanks

if you had removed cpu from socket to clean this might have bent a few socket pins which can knock out 1 DIMM.

loud cpu fan try replace cmos battery w a new one then clear cmos by motherboard CLR CMOS jumper.  if to no avail, mobo is gone.

I had just seen this occur to one of lenovo mobo.

previously I saw it with a HP mobo.

funny things with those boards were they still posted once after the cleaning but then refused to do more.  the last post was before they went belly up.

@redxps630​ You're right it's even gotten worse now. I tested it with another cpu no boot and the fans spin very low. The power supply tester indicated at first that the motherboard power works but not anymore
