Hi, my computer has been acting really weird lately. Ever since I removed the computer fan to clean it and Installed it back, it starts to get laggy and slow. Everything becomes so laggy and slow. Occasionally, my computer restarts every 5-10 mins. I think it is because of blue screen? Sometimes the blue screen pops up and sometimes it doesnt. 


Thanks,
bing

What fan...did you remove?  A system has several fans in it.

 

If you removed the heatsink...did you reapply thermal lubrication?

Yes i removed the heatsink fan and no i did not reapply thermal lubrication. Is reapplying thermal lubrication necessary?

Applying thermal paste between the CPU and heat-sink should not affect the ability of the fan to work. Check to make sure your power connection from the fan to the mobo is secure.

 Ive connected the cpu fan to the mobo "CPU FAN" but still no luck. All the fans are working though.

First thing to do is get a Test Light and make sure there is power at the fan plug point and the wires were not pulled out when you played with the fan.

 

If there is power at the plug and not at the fan, then the fan is broken / burned out.

 

The chance of this being a coincidence is very remote, so triple check the connections are correct.

No wire/cables are preventing the fan from functioning properly?

No cables are preventing the fan from functioning. I plugged the 4 pin fan onto the 3 pin sys fan header and it still doesnt work :-(

Then...perhaps your fan is dysfunctional...and needs to be replaced.
