I will buy new graphics card ati radeon 5670 that need 400 w.. on my power supply says max 305 w and peak 400w... i dont know whats right.. does it have 305 w or 400w?

The PCIE slot on your mainboard is v1.0; this should work fine with a PCIE v2.0 card (which is backwards-compatible with v1.0), but not the v2.1 cards. Make sure you also check for power requirements of any potential card. If your PC has a stock PSU, it's quite likely that a PSU upgrade will also be needed.

does the power supply you bought have a pci express power connector on it to allow the card to receive the correct voltage requirements, as that card is compatible with your system

you may need to change some bios settings i don't know what type of BIos you have but the setting would read something like: initial display on boot...and the options would be onboard or pci make sue its pci

^but befor you try that try booting up your pc with the graphics card plugged in (if you haven't already tried)

It is the best card for gaming.before you read game instruction and you buy a graphic card.

Make sure you set the primary graphics in the bios to pic-e and you will likely have to upgrade your power supply as this card requires at least a 400 watt you pc came with a 285 watt not near enough power for this video card and could be your problem

The motherboard has a PCI-E slot, so the Radeon card will fit. You might need to upgrade your power supply, as a 400-watt supply is recommended on AMD's site for this card. Otherwise you shouldn't have any problems with the new card.

Hello,
Go for ATI Radeon HD 5570 ,it comes with DDR3 memory module and 1 GB RAM and costs
around Rs.5,000.

And if you can dish out a little over Rs.1,000 more then buy ATI Radeon HD 5670,it has got
DDR5 memory and 1 GB RAM,it costs around Rs,6000.

Both the above mentioned cards are supported by your motherboard should provide decent performance in all new games at moderate graphics settings.Hope it helped.

did you uninstall the ati graphix drivers before installing the new card? have you made sure that your power supply is adequate for your new card

Good news, you can upgrade the graphics card with almost any current PCIe (PCI Express) video card. Once you install a new graphics card in your system, the ATI Radeon x200 will be disabled automatically, as per the manual.

The one caveat is that the board is not PCIe 2.0 compliant, so any video card that requires PCIe 2.0 compliance will not work. This is not an issue as almost all modern graphics cards work on PCIe 1.0. However, make sure to check the requirements o fthe card before you buy it.

As for the most suitable graphics card for you, its hard to say without knowing what tasks you wish to use this computer for and what is your budget. If you are only using it for office tasks, then the onboard graphics processor is more than enough for your use.

I should mention, that the motherboard processor support constrains you to the P4 series of CPUs. This is fine for moderate tasks, but if your gola is to play a game like Crysis, then even the most powerful, multiGPU graphics card will only make the game playable. You will probably never be able to max out your frames per second.

That said, the board supports up to a 3.4ghz CPU, which is fast enough to play almost every modern game if you upgrade to a powerful graphics card.

If you wish to do 3D graphics design, I would not recomend upgrading the video card for this purpose. Video rendering and processing stil does rely on the CPU. However, if you look into nvidia's CUDA framekwork, it is possible to offload rendering to the GPU. This is probably not worth the effort unless you are relaly short on cash.

Bottom line is, yes you can upgrade no problem. As for the best video card, I do need to know he reason you wish to upgrade the video card.
