Monitor keyboard and mouse won't turn on! please help!

[Gulredy]

So it happenened to me yesterday, that Just browsing the internet the screen turned into a striped grey screen. Tried ctrl+alt+del and it turned back on. It did the same thing when trying to play a video etc, so I've installed the newest graphics driver. Turned out it was not the issue as it continued the symptoms. Turned off pc then removed the graphics card and cleaned it.
After that it could not start as the screen was totally blank. Tried to remove the rams one by one and replace them again one by one but still no luck. Then I've removed the battery wated more Than 10 minutes but still not better. Even more the keyboard and the mouse did not get any power after this point. I have onboard graphics card so i've tried to remove the graphics card and start it with only this but still no luck at all. The monitor senses that the cable has been plugged it but nothing happens and it goes into power saving mode as there is no sign from the graphics card Just like when the pc is turned off.
The Psu is rather new not even a half year old (fsp hyper 600) so i would say it could not be the issue.
But I will try it with the old one.

What could be the issue here? Could it be that the motherboard is faulty? Its very old, more than 8 years...

That definitely sounds like either a dead motherboard or processor. If it's 8 years old, you might consider upgrading both (and the RAM, if applicable). But if you really want to save a buck, check the PSU; it's not likely, but one in a million does happen from time to time, and you should still be under warranty.

swap out the cmos battery if it weak some mb wont post. on the mb look at the caps look for any that are leaking or swelled. google the model of your pc and mb for leaking caps or recalls or class action. some older hp and dells had bad caps class action lawsuits when a bunch of bad china caps got into production parts. with a test power supply and a case speaker if you remove the ram if there no beeping the mb or cpu may have kicked the bucket.

Forget the cmos battery... that is rarely an issue and is typically used to reset the bios to default settings, however, a waste of time since there are almost always jumpers on the motherboard to accomplish this. It appears your system will not post, when the post is complete you will typically hear a beep on a desktop system. Then the boot process will begin. The pre-post is basically your BIOS trying to confirm everything is okay with the system board, PSU and CPU, in some cases certain peripherals which could include the keyboard but never the mouse and often times not the video card. I am assuming everything was working for a certain amount of time and then poof... problems. I would suspect your motherboard.

any beep?

try power on without ram, any beep?
if no beep without ram, very likely its your mobo.

I've tried with a different psu (my old one). I've only connected the ATX_12V_2X4, the main motherboard connector (the widest connector) and the video card. No hard drive or anything else was connected, so i should be able to reach the POST screen buz the issue was the same. No power on the keyboard nor the mouse, and the monitor did not get anything from the pc either.
I guess it can be said the the PSU is not the problem after all!

I don't have a mobo speaker so I can't hear any beeps. Today I've changed the ram and the mobo aswell but no luck, the pc still won't get to the POST screen. Keyboard and mouse won't light up, neither I can't see anything on the monitor... 🙁

Any ideas?

 

[Gulredy]

Also changed the cpu but still no POST screen nor light from keyboard mouse.
So far :
Psu - checked with old one should be okay
Motherboard - bought a Newer used one
Ram - bought newer used one
Video card - old board had an onboard one but did not worked with neither that one so i assume it is okay.
Processor - tried out with a similar am3 cpu which definitely works but did not worked in my rig

Any suggestions?

get/buy a mobo speaker?

Assuming all the physical components are now good/proven to work: Motherboard may not be compatible with the RAM (different speeds). If you can, check the model number to see what the specs are, and if they match the motherboard specs.
