hey there, im a new person here...
anywho.
I have a Medion M³ director 4500
In January, I had a problem where I woke up, in the morning (I had left my computer on all night) and the screen was frozen, even the date and time was frozen, so I did a reboot. Nothing was being sent to the monitor. I tested it with another monitor, and nothing was being sent either. So I went to the store and bought a new video card, came home, put it in, and everything went fine.
This time, The same thing happened, came home put it in, and it didnt work. Nothing happened.

When I start the computer, the fans turn on full blast, but never slow down. No beeping, no nothing. The hard drive is running, I can feel it spinning, the cd-rom drives will open and close, but cds are not read if I put one in. There is no display, nothing is being sent to the monitor. I took out the RAM sticks and put them back in, to make sure they were in good and tight, still nothing.

I have no idea what could be wrong, or how to deal with it, my knowledge is pretty basic with the hardware of computers.

As started, the next useful step is a methodical, minimal-configuration POST test and some basic power/motherboard checks that go beyond swapping the GPU or reseating RAM. The goal is to eliminate PSU, motherboard, BIOS, and CPU as sources in a logical order so decisions about repair or replacement are evidence-based.

A practical diagnostic path:

  • Perform a minimal boot (only motherboard, CPU, one RAM module, PSU and either the discrete GPU or onboard video). Remove drives, optical, and all extra cards. Use a motherboard speaker to capture beep codes if available.
  • Clear CMOS (jumper or remove the coin cell for a few minutes) to rule out BIOS corruption or bad settings.
  • Verify all power connectors: 24-pin ATX fully seated and the 4/8-pin CPU power plug present. Confirm any GPU auxiliary power (6/8-pin) is connected.
  • Test RAM one stick at a time in every slot to exclude a bad module or slot.
  • Swap or test the PSU: measure +12V, +5V and +3.3V rails with a multimeter or use a known-good PSU. Faulty PSU behavior can power fans while preventing successful POST.
  • Visually inspect the motherboard for bulging/leaking capacitors, burn marks, or blown components and check for loose or damaged front-panel wiring.

If the system still fails to POST after those steps, the most likely culprits are the motherboard or CPU. OEM systems sometimes use proprietary boards or connectors, which makes direct motherboard replacement harder; in that case options are sourcing an identical OEM board (check the PCB model printed on the board), transferring components to a retail ATX board and case, or recovering data by connecting the drive to another system with a SATA-to-USB adapter.

Safety/cautions: always disconnect mains and ground yourself to prevent ESD when handling components. Diagnostic steps that involve swapping PSUs or removing sockets should be done carefully or by a technician if uncertain.

How old is your motherboard? It sounds like it might be part of the issue if not all of it.

almost 2 years

(thank you so much for replying!)

Yeah that motherboard seems pretty old.

Some of the symptoms sound like they are chipset related (north and south bridge).

At this point I would say try the video card in a different computer, maybe a friend's computer or a different one you own, and see if you get a video signal from it. If you do, you can cross the video off the list. Then I would try the memory, since video cards don't usually display without memory installed and detected. If you are able to test the memory on another machine that would be ideal. Other than that, your motherboard sounds suspect, and I would recommend an upgrade (2 years is a long time!)

Some other people might have some valuable input on here, however, so you might want to wait a while before trying anything rash, like pounding your mobo with a hammer or something.

haha 2 years is old? Really? wow!
I thought that was pretty new...ha
When I bought my computer it was top of the line, so I have been told. I was going to test the motherboard, but the hookup to my computer is a sata, and the only other computer in the house is a 5 year old dell, and doesnt support anything from my computer. POOP, yes

Well I could be wrong about it being old; some people still use systems from the 3-5 years ago. but I usually upgrade pretty often because I play computer games. It might not be so much that your motherboard is old, but that it's just developed a problem and it has gotten worse.

geez, this is terrible. I can not find a motherboard for my computer anywhere.
Even the tech guy said that he had never seen a setup like mine. He told me to just go and buy a cheap computer and transfer everything from my computer to the new one, because I would have to get a motherboard imported.
He doesnt actually know whats wrong with it though...
