Why is my desktop beeping after cleaning cpu fan?

Specs: Desktop pc
I cleaned cpu fan..after closing up and restarting their is power, fans are running but its beeping like there is an error...im hoping its not a static electricity issue..i used a vaccum to start...says no signal to monitor..im at a loss...also if the thermal paste was mostly gone do i need to reapply it?

Tell us more about exactly what you did when cleaning the CPU fan. Did you remove the heat sink (I'm not saying you should, only asking if you did)?

Also let us know the make and model number of your PC and tell us the number of bleeps you are getting (they can be in patterns of 3 etc)?

"I used a vacuum to start"
Sorry, not understood.

Always pop back and let us know the outcome - thanks

"im hoping its not a static electricity issue..i used a vaccum to start"

If you used a vacuum inside the case, it's very possible a static discharge damaged the motherboard.

"says no signal to monitor"

That's because the CPU or motherboard has a problem.

"if the thermal paste was mostly gone do i need to reapply it"

Thermal paste doesn't breakdown or evaporate so I don't know what you mean by "mostly gone". But if you actually removed the heatsink from the CPU, all traces of the old paste MUST be removed from both the CPU & heatsink. Old thermal paste should NOT be re-used. A fresh amount of thermal paste should applied in accordance to the instructions for your CPU type. The application methods can be found here: http://www.arcticsilver.com/methods...

"I did remove the fan"

Still not clear. Did you remove the fan from the heatsink or did you remove the heatsink/fan from the CPU? If you removed the entire HSF & broke the thermal paste bond with the CPU, the old thermal material MUST be removed & replaced. "MUST" is in caps for a reason. The system will not boot if the old paste is re-used.

"I've screwed the motherboard haven't I?"
Possibly but there is a strong possibility this is down to local overheating - see #4.
Make sure you apply the thermal paste "exactly" in accordance with the link in #2.

Worry about the electrostatic discharge ONLY if the proper removal and reapplication if the thermal paste does not solve the problem.
Also there are other possibilities like you may have nudged the RAM or video card (if any) so that can be addressed after you read the directions supplied above and follow the instructions for your CPU type. Make sure that you reinsert the plug for the fan into the correct (CPU Fan) jack.

You have to be a little bit crazy to keep you from going insane.

Yep, when RAM has been sitting in one place for years oxide forms on the edge connectors except where the actual contact is made. An imperceptible movement can shift it onto the oxide and cause issues. Same applies to any circuit card with edge connectors. The usual trick is to clean the edge connectors with a soft pencil eraser then pop the RAM (or whatever) in and out a few times to clear any oxide off the socket itself.

Bleeps are often related to RAM issues. The reason I asked for the make and model number of the PC is and how many beeps is that we can check out the beep codes. If you don't make any progress we still need these. All questions we ask are for a reason.

Agreed, but never use a vacuum to clean out a machine again.

So i am impressed with myself...i got thermal paste...cleaned off old paste from heatsinks on cpu..reattached and BAM!!! I am good to go...running like a charm...thanks for all the help guys..it was a heating issue and not an electrostatic charge issue...I feel like a motherf!#king boss..lol

Good to hear but in future there is no need to remove the heat sink for cleaning. With the aid of a small brush and some canned air you can clean things up just fine. Sure, you clean the fan but far more important is to clean the fins of the heat sink. Some of them can be cleaned by gently using the brush between the fan blades and around the outside. If you feel forced to remove the heat sink then you obviously now know what to do. Well done!
