Problems with a Medion Computer

[Elsarild]

Okay, so heres the jist of it, I was called out to fix up a Medion PC MT 7 that woulnd't start up, after an hour of troubleshooting and getting nowhere, I had to say that I was sorry I coulnd't help, and take my leave, I told them I would see if I could find a solution and get back to them.

When the computer is powered on, it shows a small post bios screen of intel on it, I can access the Boot menu, and I can access the bios, after checking everything, clearing the CMOS, and resetting to default, it did nothing.

When the Post Bios Screen goes away, it just fades to black screen, and then, nothing, it never gets anywhere from there.

I tried swapping the RAM, diffrent socket, no change.

I tried boot up on an Win XP cd, but when it was booting up, the computer rebooted, kept doing that

I tried booting on a Vista Cd, both 86x and 64x, but as soon as the CD was done loading, it went into a console and just printed out a long vertical line of "H" It did the same with an Windows 7 install CD. And Also Vista 86x & 64x recovery CD's

I have never encounted this before, BIOS seems to work, so does RAM, HDD and graphics card, but after the BIOS post message, it just goes black, and all my boot CD's was worthless.

Anyone who can help?

By "swapping the RAM, diffrent socket" do you mean you used the same sticks but just in different sockets in this pc, or have you tried this RAM in a different pc/tried different RAM in this pc? If it's the former, the memory might be buggered.
Are all boot options correct? I had a weird error once where I got a BSOD and my storage configuration in the BIOS got all messed up, not recognising my SSD and when it did (after reseating the SATA cable), having the wrong device priority and boot order.
How do you know it's not a HDD problem?
Have you tried sticking a different DVD drive in there and then retrying the windows boot discs? Doubt that's the problem as that would mean it should run fine as long as there's no bootable disc inside, but it never hurts to be thorough.
