Problem - Monitor, keyboard and mouse do not work after starting the computer

Hello
Today I had a problem with the computer. Well, after firing it [the button did not want to work, it worked only after resetting the power supply], my monitor does not receive the signal. the problem is not with the monitor as it runs on the laptop.
A moment ago I noticed that the keyboard and mouse were also not lit. I also understand the mouse - it's on usb, but the ps2 keyboard should be responsive. The windmills are spinning, you even hear some sounds coming from inside [I think a hard drive or a dvd drive]
From what I tried to act on my own:
- podociskanie cables
-remove the frame and translate to other slots
-you take the prock and press it
-bios reset [by removing the bios battery for about 10 minutes with the power supply off]
Unfortunately, the problem persists. C Is it possible that this is a power supply? Everything seems to be spinning and glowing, but since the keyboard also does not work ... it's probably not the problem. As I said, everything worked perfectly yesterday.
Computer Specs:
- RAM memory: DDR3 - 4GB
-Processor: AMD Phenom x4 [I do not remember the timing at this point and I do not have a box]
- Motherboard: ASUS M4A88TD-M EVO / USB3
-Graphic card: and here it is interesting because it is supposedly integrated with the motherboard and I have no idea what it is. but it works fine ...
-Power supply: Logic 500ATX - 500w

// edit
After another bios reset, the computer hangs on Scan Devices, Please wait ...

I am asking for help as soon as possible.

greetings

As I understand after resetting the BIOS, the image is already there? Disconnect all devices from the motherboard - disks, CD / DVD drives. Disconnect the AC adapter cables from them as well. Leave only the keyboard connected and try entering the BIOS. Do you own or can you borrow a multimeter (voltmeter)? If so, check the voltages and give them back - possibly a 5V line should be there. If you manage to enter the BIOS with only the keyboard connected, try to connect the hard drive (under the board and the power supply - of course with the computer turned off!). If it freezes then, possible damage to the HDD.

The problem was, after shutting down the computer, the problem was again happening. So I reset the bios again, it crashed again, so I reset it again and now it doesn't even have a picture again or the key doesn't work. As if I didn't even want to reset my bios.

// that I did as you said, but as I mentioned above - I came back to the starting point again.
Unfortunately, I am unable to mount a voltmeter.

What is the power supply there? Do you have the option to replace the power supply with another, 100% efficient one?
Is there a loudspeaker / buzzer on the disc? If so, remove all memory chips and start the computer (other devices disconnected).
It will be hard to do something, apparently you will have to bring your computer in for repair ...

logic power supply 500atx - 500w.
I can not get such a functional power supply ..
I don't think there is a speaker connected to the disc, and if it is alone, I don't know if it works. the computer has just returned from a thorough repair and it worked fine for a few days. that's why I do not trust websites etc.

I also put a photo of the computer

You don't trust websites, but you don't have the basic tools. Without them, you'll have a hard time repairing your computer.
Besides, if

then return it to the complaint, you have this right.

Photos must be of good quality and properly posted (read instructions for pasting photos )
Besides, such a photo won't tell us much ...

Well, unfortunately, these consumer 2 weeks have already passed and I am not able to bake them well. Unfortunately, the computer only reached me a few days ago. by that, it was only checked after returning from repair.
So the only salvation is to throw the next few stacks down the drain?

What consumer 2 weeks ??? You have 2 months to report a defect from its occurrence, for at least one year from the date of repair. The websites are subject to the Act on detailed terms of sale. The service has two weeks to respond to your complaint.

Thanks for the information, if I can't do something myself, I will probably take your advice

Sorry with the post under the post, but no one will notice edita.
So:
Today I turned on the computer [everything was disconnected after yesterday] and the bios was loaded, while searching for devices an error appeared in red that nothing was found.
So I turned off the computer and burned the disk. After booting, everything works fine again.
Can anyone tell me what was wrong here and how to remedy it in the future?
I would be very obligated ...

Regards and I hope for a quick response

Without careful analysis no one will tell you that. Despite the large number of specialists, the electrode suffers from a notorious lack of clairvoyants and fairies.

There may be a power supply - after disconnecting the power supply and discharging the capacitors, it may pretend to be "normal operation" .

There may be badly seated and / or dirty / tarnished contacts of expansion cards - graphics card, memory, individual connectors.

In either case, without removing the cause, the problem will come back.

Hello

I have a problem with the keyboard. The keyboard only works in bios, then the following message pops up and I can't do anything

all I tried to do was restore the optimal bios settings and I still have ideas what to do

fiftyfifty91 Enter BIOS, find USB Keyboard Support option, set it to Enabled.

I did Load Optimized Defaults before (I think it should turn on the keyboard) because I did not find the keyboard option in bios and it did not help

Enter your motherboard model.

I don't know where to find it, but the bios looks like that

You can read the CD model directly from it after opening the computer case. Also from Windows with HWiNFO .

Check the Integrated Peripherals-> USB Keyboard Support section to Enabled.

Thanks everything helped but I wonder why Load Optimized Defaults didn't help? it probably resets Bios?

It does not reset the BIOS, it only loads the default "optimal settings" - but optimal in the understanding of the manufacturer. This option is not used, because these settings must ensure high compatibility anyway (the manufacturer does not know what you are going to connect). BIOS reset is to remove the battery or set the appropriate jumper on the motherboard. Appropriate configuration should be made according to the connected equipment. Create a separate topic, then I can help you with the appropriate setting.
