I recently bought a custom built PC and it worked fine until i tried to change the processor (which didnt work) then i kind of put my finger on the thermal paste so i cleaned the entire thing with hydrogen peroxide solution. I even cleaned the part of the heatsink that was covered with thermal paste and put it back very tight and made sure it was rigid in place then booted it up and nothing shows on screen only beeps. Pls help!!

do you know what make and model the motherboard is?

 

please tell me when reconnecting the heatsink you didn't overtighten the screws as that could nuke your motherboard

 

did you replace the thermal compound your removed?

cleaned the entire thing with hydrogen peroxide solution


What areas do you mean by "entire thing"? Hydrogen Peroxide is a powerful oxidiser and is used under carefully controlled conditions in the situations where it is appropriate in production processes for electronics. Unless it's very well flushed, water will evaporate preferentially and leave concentrated Hydrogen Peroxide which I would be concerned could do all sorts of undesirable things.

As already mentioned, did you replace the thermal compound with an appropriately small amount of quality thermal paste? Why was it that changing the processor didn't work? Could this have provoked some damage (e.g. CPU with too high thermal rating)? How was the "very tight" mounting of the heatsink achieved?

Hydrogen Peroxide is usually 3% with the remaining 97% water, it very well may be shorted out.  Take it apart again use alcohol to re clean everything then let it dry over night keeping your fingers crossed!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I didn't even pay attention to the hydrogen peroxide part but yes I would never clean any electronics with any type of peroxide and very carefully do it with a dust free cotton pad and rubbing alcohol, also make sure ANY and ALL repairs are done while grounded via a wrist strap if this is your first time doing a repair like this as static discharge can cause a whack ton of issues

I hope you used the thermal paste when remounting the heatsink.  If you got it on you fingers, you most likely left traces of it all over the CPU socket.  Alcohol, q-tips will clean things up..  I use an acid brush with short bristles(half inch) and alcohol to clean the board itself.  Let dry overnight.

1. I did not reapply thermal paste
2. I cleaned only the surface of the processor of the processor and the copper circle onbrhe heat sink, though i cudnt get rid of mark of thermal paste on the processor
3. I used 20VOL hydrogen peroxide solution
4. The processor didn't change since it was smaller in size

After removing the processor's of my old and new PC, I realized my old processor was too small for the new PC so I put both back (i opened my new PC processor for the first time). After putting both back in, my old pc worked normally but my new PC started beeping so then i cleaned it as mentioned

And also the heatsink was quite rigid in place, it wudnt move even a bit when i lifted it

Reapply a thin film of paste between the processor and heat sink and remount in the socket.

well if you didn't re-apply thermal paste and now it only beeps id say its safe to say it could be cooked CPU

I wudnt say its cooked CPU aince the beeps came first when i touched the thermal paste then put it back in. Later after hearing the beeps I cleaned thermal paste and it made no difference
I am currently looking for thermal paste around my place so yeah

Beeps will normally provide an error code, what format do they show? Continuous, a number sequence repeated after a pause? Long, short?

If the CPU is toasted, thermal paste won't revive it.  But you have to try.  The beep code sequence is important.  A steady single beep indicates the first memory bank is bad, it needs that RAM in order to begin loading anything from the BIOS.

Beep1 -smallpause- Beep2 -smallpause- Beep3 -LONGpause-
Beep1 -smallpause- Beep2 -smallpause- Beep3 -LONGpause-
Beep1 -smallpause- Beep2 -smallpause- Beep3 -LONGpause-

Basically it pauses for a second after every beep then about three second pause on the third beep

BEEP BEEP BEEP... BEEP BEEP BEEP... BEEP BEEP BEEP...
That's all ik

Depending on the BIOS type, the commonest meaning for 3 beeps is a RAM problem. You might have dislodged a memory stick when dealing with the heatsink. Try re-seating the memory in the slots, if this makes no difference, remove all the memory sticks, boot up and see if the error code changes.

 

One other thing to try is to clear the CMOS memory in case it has been corrupted. You wouldn't normally expect that to cause error beeps, but it's one thing to eliminate. Your description of the problem occurring immediately after touching the top of the CPU suggest the possibility of a static discharge, which could corrupt the CMOS data, or in unfortunate cases, corrupt the BIOS or damage the CPU. Hopefully it isn't either of the latter.
