Hiya,

I just bought a new graphic card for my computer. Its the Radeon HD 5750 1gb and before that one I had the Nvidia GeForce 8600 GT. After my dad replaced the graphic card I turned my computer on. And like 5 seconds after I press the turn on button I hear like 6 beeps from the computer, and the monitor wont work aswell, but there is light on my mouse and keyboard so I dont know whats wrong. Do you?

PS. I know my english isnt that good (its my secondary language) and also, Im kind of a newbie with these computer things so it would be greatly appreciated if you would write detailed.

As described: the system powers (keyboard/mouse LEDs) but the monitor shows no signal and the PC gives about six beeps. That pattern means the board is detecting a hardware initialization failure during POST. Beep “meanings” vary by BIOS vendor, so the safest first step is to treat this as a hardware-startup problem and follow a short, careful troubleshooting workflow rather than assuming a driver issue.

Quick, safe checklist to run now:

  • Power down, unplug the PSU, ground yourself, then reseat the Radeon so it sits fully in the PCIe slot and the retention screw is tightened.
  • Confirm the card’s required PCIe power connector(s) are plugged directly into the card from the PSU (not an adapter from a Molex splitter). Check the GPU fan(s) for free spin.
  • Swap the monitor cable/port (DVI/HDMI/VGA) and try a different cable or another display to rule out cabling.
  • Reduce to a minimal POST: CPU, one RAM stick in the recommended slot, GPU, PSU, and monitor only. Remove drives, USB devices and extra cards. Power up and note exact beep pattern (count and long vs short).
  • If it still fails, clear CMOS (remove battery for a minute or use the motherboard jumper), then test again.

Also gather diagnostic signs before contacting support: are the GPU fans spinning? Any diagnostic LEDs on the motherboard? Exact beep timing? Those details matter when checking the motherboard manual for POST codes or when contacting the card vendor for an RMA. As recommended, consult your motherboard manual for the precise beep-code mapping; as suggested, double-check physical connections. If the card shows no signs of life after these steps, try the card in another known-good PC (or a known-good card in this PC) to isolate a faulty GPU versus motherboard/PSU fault.

Put your old video back in and boot the system, if it works ok then you know that the issue is with your new card (as it appears to be). If this works, research your computer system Brand and Model # to find out what motherboard you have. Once you know what motherboard you have you can search for "POST BEEP Codes" and should be able to find a list telling you what your beeps mean.

Other possible issues: You are switching from an NVIDIA based video card to a ATI based videocard. Did you make sure to UNinstall the old NVIDIA graphics drivers BEFORE you installed the new ATI graphics drivers?
