AMD RX 460 4GB with no signal

Hi everyone!

First of all thank you for the support!

I bought a MSI RX 460 4GB OC GPU but there is no signal on monitor (gpu fan works, no motherboard sounds).
Is this caused by my motherboard? not enought voltage or what? i'm really confuse. Thank you so much, really apreciate it!

FULL SPECIFICATIONS:
Motherboard Model: MS-7728 (http://www.findlaptopdriver.com/medionpc-ms-7728-mother...)
Processor: Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz (8 CPUs), ~3.4GHz
RAM Memory: 6144MB DDR3 1333
PSU: 500W TQEP-500SSE Ecopower II ATX 500W (updated from 350W a couple of days ago)
NEW GPU: MSI RX 460 4GB (75watts)
OLD GPU: AMD Radeon HD 6450 1GB (26 watts PEAK)
BIOS version is E7728MLN.209

Thank you for your time

Did you remove all the HD 6450 drivers correctly? If you removed the HD 6450 by just deleting it thru "Device Manager" without removing it using "Add Remove" Crimson (or Catalyst)drivers, the system will sometimes hang for quite along time and make it appear like the card might be "dead" with no display while Windows tries to install drivers for a new card. If possible try it in another computer.

Yes, I removed all drivers with Display Driver Uninstaller utility, but nothing....
When I plug the new card now I realiced that mouse and keyboard doesn't work, no led display, maybe is just not enought voltage.... this motherboard is shit right? someone know some cheap MBD arround 50-60 bugs that can handle my processor and new GPU?
By the way I entered BIOS pressing DEL hoping can change voltage options or something about PCI slot but in Advanced can change anything about GPU or PCI options, just can enable or disable PCI slots.
- BIOS version is E7728MLN.209 and my new exactly PSU is TQEP-500SSE Ecopower II ATX 500W.

So this RX460 only uses the Pcie slot for power and does not have a 6-pin connector? Its possible that the slot does not supply Pcie spec which is 75watts. That would mean a problem with the Motherboard, but there is always the possibility the card is bad. Would be nice to try it in another system to see what happens.

Clear the CMOS with the JBAT jumper and try again?

Try turn on monitor manually when the pc have entered windows.

Normally when you first turn on a PC you'll see the Bios info for the motherboard (the part that says "hit Del to enter BIOS..."). Do you see that? If you see that but the screen goes black once Windows starts launching then it's probably a driver issue. If you don't see anything then it's more likely hardware related. If hardware related, make sure the BIOS is set to use and discreet GPU versus the integrated GPU in the CPU, reset the bios, etc.
