Hi Guys,

I am facing a new problem today.

On booting the PC, the display is not available. and all system fans are working.
The CPU fan is making huge noise, and I believe its a CPU issue.

AMD FX6300, Corsair 8GB DDR3, Gigabyte 78LMTUSB3

I know why this problem occurred, as the system was working perfectly.
when I was in office, my cousin used my system and he (stupidly) forgot to remove the Cabinet cover (cloth) and used it as it is. and now the system is not booting :( with CPU fan making huge noise.

what is the remedy ?

try resetting your bios settings by using the cmos jumper(refer to your motherboard's instruction manual for details)and check if the problem persists.

u mean removing the CMOS battery and putting it back again ?

It can be CPU issue however sometimes poorly seated RAM results in system behaving as if CPU is not present with similar outcome.
Assuming you have a cabinet speaker installed and plugged in to mobo front panel header, remove all RAMs, disconnect HDD and boot the PC. You should ideally hear some beeps indicating RAM is not present. If this is true you have a working CPU & Working BIOS.
Try reattaching RAM one by one and check if the system revives.

Run your system with bare minimum. Just a single RAM (initially none rather) SMPS and keyboard and display and troubleshoot from hereon.

Try reconnecting all cables and ensure they are firm including SATA cables, monitor cable etc

Re-seating the CPU & heat sink might be subsequent line of troubleshooting if resetting CMOS, RAM etc don't work. Leave that as a last option though. You should apply a fresh layer of thermal paste after CPU & heatsink is removed and replaced again on to the cpu socket.

Is it possible that the CPU thermal paste has dried up ? which is causing its FAN to make to noise

FAN noise can be due to multiple reasons. Fan is set to auto mode resulting in higher RPM due to high CPU temperature.
There's a lot of dust accumulated on the fan blades causing it to make noise.
The locks / screws holding the fan on to the heat sink are loose somewhere

Try what others have suggested but either it's the gpu or the motherboard itself acting up.

BTW, I did not catch what PSU you are using ? So please let us know about it.

Corsair RM450 and my GPU is already gone kaput.
Running on IGP.
I suspect some issue with CPU now.
Initially the system booted fine but with high CPU fan noise and now system is not booting but noise is still there

faced same thing with one of Asus motherboard + AMD cpu - had to replace the motherboard.

OK.

Is it advisable to dry the desktop in Sunlight ? to remove moisture

sunlight should not do any harm but still it could be damaged more by creatures or insects. So better would be to get put the motherboard inside of a box of silica gel packs but still I don't think humidity is the culprit behind the issue you're facing .. the motherboard is acting up and it's a sure sign it is going non functional.

MOBO and Procy are very hard to defect at this early.

First clean the PC properly (Use a blower, soft brush and lint free clothes)
Detach all cables (power+data) and reattach.
Check only display to make sure no issue with Display
Reattach and power on the system.

This would give you a fair idea where do you stand now.
Test your equipment in this order in case system still fails to boot.

CMOS battery
RAM
PSU
MOBO

I will have to be careful while detaching CPU as the pins can be damaged.

Don't detach CPU yet. Keep it for the last stage.

Remove all else. You may face trouble detaching the FAN over CPU too. So, be careful.

I have uploaded the CPU pic and I think the thermal paste has dried.
Can u pls check?
The system was used for 3 hrs with cabinet cover on it. And I think the exhaust air kept inside dried up the thermal paste

I am going to call a technician if nothing works the mobo and CPU has 3yrs warranty. So I think I can RMA it. but I want to find the faulty piece

THR might be issue with boatloader partition of HDD. Can you try putting windows bootable and see if it boots up with OS cd ?

Did u read the OP?
It's not the OS or HDD issue

I read it, but recently I have faced same issue on my PC, no Display fans working. I called up technician and after all the tests(at his place) the conclusion was boot loader partition's data was corrupted. After fixing the boot manager it is working all fine.

So I thought maybe this can help you up...

As you've already removed the FAN. The only option is to clean PROCY surface properly and apply new thermal paste.
No question of analyzing if the existing thermal paste is good or dried up now.

Make sure to clean your PC properly and that reminds me that I need to clean my PC too.

But did your CPU fan make loud noise like mixer grinder?

I don't have TP right now :(
Will need to buy one.
Suggest some good budget TP.
Btw shud buy TP or call a technician?
What if even after applying TP the system doesn't work?

TP is very cheap. You can buy any one.

Better assemble and boot it up. IF still not functioning, then call technician.

Remember, it requires very small amount of TP to spread. Don't pour a lot over the surface. Just a thin layer is required.

Hmm, now I have to check YouTube videos on how to apply a TP :)

Do i have to look for thermal ratings? I believe there are different thermal compound ratings available

Use Deepcool Z5 - used many times on processors and gpus and can vouch for it.

If u believe the thermal paste has dried y don't u try replacing it ?

I have got new mobo replaced in RMA.

Connected the pieces and the system has booted fine and no shutdowns.
But after some time the processor fan is making noise, but the system is working.

Can somebody tell me good CPU temp apps for AMD CPU ?
I have used CoreTemp but its only displaying CPU#0 details and temp as 35 deg Celsius.

in addition to temperature monitoring also check for
-dust on fan blades
-tighten all screws holding fan to the heatsink
-check how the cpu fan controller is set in BIOS- fixed or variable speed as per temperature
-enable AMD cool & quite setting in BIOS, if not on already (if applicable to your CPU)
-check if any software came bundled with AMD Drivers to monitor system parameters including voltage,cpu fan speed and temperature etc. When I installed my AMD Athlon CPU there was an app called AMD ET6 (Easy Tune).

- There is no dust on fan blades.
- Heatsink is not using screws instead it uses a lock system to lock on CPU
- i will look into
- i will look into
- Thanks for reminding, I have the driver CD so will install East Tune

One of my older systems' Intel stock CPU cooler has a NIDEC fan, and it typically runs around 3700rpm in the summer (No A/c at home) under heavy load. His speeds just seems above normal, but not a huge lot.

(Intel stock coolers come with NIDEC, Delta, and several other brands depending on the CPU which they come with., and some of them can be quite fast and noisy under non optimal conditions).
