[SOLVED] Got out my old PC to use but it isn't giving any POST or display ?

[josh44361431577]

Like in title, i tried cleaning motherboard, but didn't worked. I know it isn't a PSU fault because i tried it with another computer and i works good. Fans are spinning and there is hard drive activity. It just, won't give a output to monitor. I tried internal graphics and video card, but still nothing. I don't know what's causing that. Can someone help me out with that ?

Here is all of computer's specification.

Motherboard : MSI 760GM-P23 (FX) (MS-7641 ver 3.0)
Power Supply : Elementrum E2 (550W)
Hard Drive : Samsung 80GB

Do i need to update bios ? if yes how i can achieve this ? because there is no bios usb port or even bios flash button on motherboard.

can't boot without cpu

I have cpu installed on motherboard. with cooling

cpu model is AMD FX 6300

Well, you said those were the complete specs. So you're using RAM and a GPU too? What are *those*?

Ram i found in my attic and it's not labeled.

Gpu is Nvidia 710 GT

We need a lot more information before we can help.

Was the motherboard working before you cleaned it?

What was the reason for cleaning the motherboard?

How did you clean the motherboard?
1). With a can of compressed air
2). A vacuum cleaner
3). A soft bristle brush
4). Isopropyl alcohol
5). In a dishwasher (don't laugh, some people do this)
6). Did you observe ESD (anti-static) precautions whilst cleaning the motherboard? If not, you might have damaged the system with a static discharge.

Has the computer been switched off for several years? If so, have you replaced the CR2032 BIOS battery?

Was the FX6300 CPU working in this motherboard before you cleaned it or did you use a different CPU?

Is the 20/24-way ATX connector plugged into the motherboard?

Is the 4/8-way 12V CPU power connector plugged into the motherboard?

Are the unknown DIMM(s) the correct type for the motherboard, i.e. DDR3, not DDR2 or DDR4.

How many DIMMs are fitted?

Can you tell us what information is printed on the DIMM(s)?

If two DIMMs are fitted are they identical , i.e. same capacity and part of a matched pair.

Are you running the memory in Single or Dual-Channel mode?

Are the DIMMs seated correctly in the sockets?

Have you tested these DIMMs in another computer?

Have you tested the GT 710 GPU in another computer?

Please try to answer as many questions as possible. The more information we have, the better.

Motherboard was working 2 years ago when i powered this pc on .

I cleaned motherboard because it wasn't working when i taken out this pc.

I cleaned motherboard using soft bristle brush with isopropyl alcohol.

the computer was in attic for 2 years since i last powered it on. and yes i replaced old battery with Duracell DL/CR 2032 3V battery.

The FX-6300 was in motherboard all time since i bought this pc

24-Pin ATX connector is plugged in to motherboard. and 4-Pin cpu power connector is plugged in as well

yes, one unknown ram is DDR3 and it's seated properly in motherboard.

only one DDR3 ram is in motherboard.

I am running ram in single-channel mode

Yes RAM is seated correctly, i didn't tested ram in other pc, because i don't have another pc running DDR3 i have only DDR4 running pc.

graphics card is good i tested it, it works perfectly.

i hope this list helps.

That covers pretty much everything I can think of but obviously something is wrong with the computer. My next course of action would be to slowly replace each component in the computer with known working items.

So far the only thing you've changed is the PSU. If you have tested and working RAM, a spare CPU and another motherboard, it should be relatively easy to trace the fault. You just keep substituting components until the system starts.

If you don't have a complete set of known good spare parts, do you have a similiar system to test your CPU and RAM? If they work in another motherboard, that implies your existing motherboard has stopped working.

Thanks, i will reply if this will work out.

I think i found a solution! when i place a cpu in motherboard socket, cpu is getting like a black gunk on it's pins. i cleaned motherboard socket with alcohol and now i await when it will be ready to use.

 

[Misgar]

If you've got TIM (thermal interface material) in the CPU socket, you may have trouble cleaning it all out.

The CPU pins should be easier to clean but make sure you don't bend any pins or snap them off. Remember that CPUs are susceptible to ESD damage.

When you reapply TIM, do NOT use too much. A small pea-shaped blob approx. 4mm diameter on top of the CPU should be enough.

 

[josh44361431577]

yeah i found problem...

the pins on cpu were bent when i took it out of motherboard socket.

i will buy a new replacement.
