MSI K7T266 Pro2, Radeon 9600 Pro, Athlon 1700: PC Won't Boot, No LEDs or Fans

Hello

I'd like to know what could be causing the computer to not turn on. After pressing the button from the start, there is no reaction, the LEDs are off, the fans are not spinning, the monitor is black, the speaker is not beeping. The equipment started to break down for me some time ago, sometimes it did not turn on, when it turned on, artifacts popped up in games and basically that's it. The power supply is definitely working (I connected another one from a working computer), the graphics card works, I left the frame, one in the slot, the other pulled out and vice versa, and there were no signs of life (nothing beeps etc. etc.), I have no way to check the processor. I would like to know your opinion because I do not want to buy in vain. to replace the motherboard ?? or maybe something else ??

Motherboard - MSI K7T266 Pro 2
Graphics Card - Radeon 9600 Pro
Ram -2x256 400MHZ
Processor - 1700 Athlon
Power supply - Tracker 350W ATX P3 / P4

greetings

Are the capacitors around the processor socket swollen or spilled? You connected a second power supply, but is it with enough power?

the capacitors are intact, the power supply was of the same power, I do not remember which company, I only know that it was standard with a tracer or mustang housing.

Please start the computer in the configuration: motherboard + processor + power supply (but better than the standard one) + system speaker. Nothing more! Cards, memories, tapes taken from the disc.
If there is no signal from system speaker, please reset BIOS settings and reboot in above configuration.
You should hear a beep from the speaker, indicating a memory error. If it is not there, the group of "suspects" will narrow.

you can try to run a bare disc without a memory processor etc. etc.
if it does not start then:
damaged switch or any element such as connector, path
damaged power supply
damaged motherboard

The bios reset did not do anything, no reaction, I started the computer in the above configurations and the same, the switch is rather good but I tried to run it "briefly" and nothing.

What power supply did my friend start with?

It means?

Power supply - Tracker 350W ATX P3 / P4 (the one on which the computer ran before)

briefly, i.e. the computer is connected to the network, the power supply is on and I was touching both wires with a screwdriver (powerfully)

After all, I asked to check on some better power supply ...

Please try to start the computer by shorting (with the ATX plug plugged into the board) the green wire with the black wire.

Is the computer unresponsive at all, or will it turn on the LEDs, spin the fan and turn off?

1 Remove the power supply from the motherboard and short the black (ground) to green (it should be next to the black). If the power supply starts, it is functional (disconnect other receivers, drives, disks, etc.)
2 check the bios battery, although so far I have only encountered a disc that did not start on a weak battery so far, but it will not hurt
3 connect the power supply if it turned out to be in working order - the frame plate. If all the game should (I think) give out 4 short beeps - no graphics
4 if it did not start, disconnect the RAM should squeal when starting - no frame and graphics, I do not remember how many times
5 if silence, take out the prock, connect only a fan to see that something is happening.
6 if silence is either there is a disc or there is no bios in the bone (once the Chernobyl virus was cleaning the content of the bios)
If at some point it gives signs of life - slowly attach the elements to the CD [/ img]

nothing silence, only the fan from the power supply was spinning, nothing more, neither diodes, nor the rest of the fans, nor the loudspeakers; silence. As for the power supply, I have no other one, but I can borrow from a friend the one I wrote about earlier.

And does the colleague have a voltage meter - it is a very useful tool in diagnostics. If the power supply starts, it can be checked if it has all the voltage.

Due to the lack of better solutions, it can be, just write what the power supply is.
If it is the same on the new power supply, the colleague has a damaged motherboard and / or processor.

I do not have a voltage meter, but I put the power supply into my friend's computer and the computer starts, so it seems to me that the power supply is good, I am forced to change the motherboard and processor for Christmas, if it turns out that the other parts were out of order, I will add it. (next week at the latest)

thank you for helping everyone.
greetings

That doesn't mean anything.
As for the rest of the ... well, you can anyway.

artifacts are the result of overclocking / burnout of the graphics card modules ...

but this may result in uneven voltage across the motherboard ...

The fans do not spin, this may be the reason - too low power supply on the prock, too high clocking on it, or vice versa, an IDE / FDD ribbon attached

as for the artifacts, in fact, more of them popped up and faster than usual after increasing the CPU clock speed. After tomorrow, I go for new components, I will write if the card has not been damaged ... the tape is inserted well

first, the motherboard will not start without a processor.

Epitaph_PL do you have diagnostic diodes connected to the motherboard?

I replaced the processor and motherboard, the power supply is what it was, but I plan to replace it in the near future, everything smiga = D

ps I had no diagnostic LEDs

Thank you and best regards

Hello !! I have a similar problem, my computer does not start, but the green diode is lit on the motherboard.
it is good, I thought that I changed the switch to another one and so it does not even turn on the fan.

GREETING IN advance.

Friend, not only that you "hooked up" to the topic, you also dug it up! Can't see the date of the last post?
