Question My motherboard stopped working for some reason

[YiurBRO63]

I have MSI MS-7641 motherboard, and it worked fine but when i removed it from case it stopped working (no signal on monitor) . I removed ram and pc was not beeping, did i killed my motherboard by mistake?

Plus when inserting ram i hear like sand is crushing inside slot. I replaced cpu but nothing CD drive and hard drive is running when i power it, GPU is at full fan speed. If more info is needed to diagnose i will tell.

-- Update --

PSU model is Elementum E2 550W EU the age of PSU is maybe 4 years, one thing i noticed when i opened it is red liquid on the board that was hard to clean. i think it's a leaked compacitor but idk. it came with that PSU when i got it.

Disk drive is Western Digital 50GB i can't tell how full it is because i found it in this pc when i got it.

And yes Motherboard full model name is 760GMA-P34-FX

i removed motherboard so i can clean case, i got pc without any booklet or instruction / manual. all cables are plugged in but nothing seems to fix problem.

the ram was correctly placed. and still nothing
is there any way to clean ram slot ?

here are specs:
motherboard: MSI 760GMA-P34-FX
PSU: Elementum E2 550W EU
OS: it didn't had one when i booted it up first time
Hard drive: Western Digital 50GB
RAM: 1 stick, 4GB
Processor: AMD FX-4100 (i bought new to see if it works, but still nothing)
GPU: Doesn't have one.

Update your post to include full system hardware specs and OS information.

Include PSU: Make, model, wattage, age, condition (original to build, new, refurbished, used)?

Disk drives: make, model, capacity, how full?

This motherboard?

What was the original reason for removing the motherboard from the case?

Refer to the User Manual to double check all insertions and connections.

Do not force the RAM into slot. Verify that 1) you are inserting the RAM correctly, and 2) that there is no debris in or otherwise obstructing the slot.

PSU likely culprit on multiple counts: Old make/model, wattage, age....

What OS did you install? Are you able to at least access BIOS?

However, the overall hardware specs do not make for a practical system with respect to today's OS requirements and many applications.

Just inspect the RAM slot using a bright flashlight. If there is no damage, corrosion, or debris then leave well enough alone.

In any case, a replacement PSU is needed for starters. Borrow a PSU if possible for testing purposes.

If the PC still does not work then each component, including the motherboard, will need to be independently tested in a known working computer to discover the cause of the boot failures.

Do not test that PSU in another computer. Also, as I understand your post, you opened the PSU. PSUs are not repairable and if a capacitor leaked then the PSU is beyond further use and may be dangerous to use.

[Note: if you have a multimeter and know how to use it (or know someone who does) then the PSU can be tested somewhat. Not a full test because the PSU is not under load. Any voltages out of tolerance indicate a faulty or failing PSU.]

Find out which components work and which components do not work.

Salvage what can be saved and responsibility recycle the rest.

I will try to borrow PSU from my friend and i will see if that works.

i can't access BIOS monitor shows no signal.
