Ok I just install a new Video Card Sapphire ATI Radeon HD4670 512MB DDR3 when I'm playing a 700mb .avi video ... it works fine. but when I try to play a 4.5gb video ... the computer reboot. I'm currently using a 430watts power supply Do I need a bigger power supply or is there another problem?
yes my old video card was ATI Radeon HD 2400 PRO so I'm just wondering do I need more power to push the new video card?
It could be your power supply or it could be conflicting drivers, depending on your previous video card. Try uninstalling any previous drivers if there are any. If that doesn't work, then its probably your power supply. A 430 watt psu probably has very little amps on the +12v rail, which is what a video card uses. When you buy a new power supply make sure there are enough amps on the +12v rail. Most new video cards want around 28+ amps on the +12v rail, but the manufacturers are probably exaggerating on the reqs. Just make sure you don't fall for the high wattage, but low amps on +12v rail, as most cheaper psu's are like that. High quality psu's will probably set you back around a $100.
Also, are the wires that come with the power supply are the one it came with? that may be another reason because not enough power may come through
Oh one thing ... I had moved my computer into this new case that comes with the 430watts power supply. So the new video card is plugged into this new case, my old case had a 550watts power supply. This case is alil bit smaller more of a "media" design case and it doesnt look like my old PSU will fit but havn't try yet.
Well, it could be many other reason such as CPU, video driver, overclocking to memory problem. Could even be a codec problem or the file format of that file and how it was converted. What is your computer spec? 4.5gb? Is that a VOB file or DVD file?
I doubt its his CPU, since everything was working fine with his old video card. Can you check how many amps your +12v rail has? You can find it on the side of the psu. Heres an example of where to find the numbers The specs on the rest of your cpu could be helpful also. Also you should try opening up the file with a different media player. I had some weird problems with my old computer where some video files would crash with a certain media player, while it wouldn't with others.
a 430 Watt PSU is enough for a single core proc, one DVD burner and a hard drive. Not much else. Seeing as how you probably have a duo or even quad core, 2 DVD drives, and at least one Hard drive, you are pretty much maxing out your PSU without your new video card. You will need AT LEAST a 650 Watt PSU. The other thing is, before you install your new video card you need to remove 100% remninse of the old. A best way to do this is a fresh install of windows. Do that first, if you still have issues, then buy a new PSU.
Computer Spec: Intel Core Duo 2.33 ghz Gigabyte GA-73-VM-S2 Corsair 2GB DDR2 Sapphire ATI Radeon HD4670 512MB DDR3 yeah thing is .. it work fine before in my other case with the 550Watts PSU this new one comes with a 430Watts PSU. I'm watching dowloaded Blu-ray converted movie files .mkv Try watching The Dark Knight 8.3gb ... same thing. but smaller .avi 1gb movies has no problems.
overkill on the video card your computer will not fully utilize this card, but thats not the point really i dont know why file size has anything to do with playing video... it probably has nothing to do with it delete the 4 gig file and let it go
The thing is my HD has over 18 4gb movies that I download and store I mainly got this new video card to watch these converted Blu-ray movies
um what? The card fits with his system pretty well. File size has A LOT to do with playback. Depending on where the video is drawn from (Hard Drive or DVD) the PC will cache as much video as possible. When he's playing the AVI, it's an encoded process pushing more to the processor and asking less of the video card because it's pushing a smaller number of bits per cycle to the video card for processing and output. Whe he's playing a 4.5 gb file the video card is taking more and more bits per cycle. If you've done video editing, it's the notion of cutting (scrubbing) encoded video vs raw. When you watch a movie that is 4.5 gb, more likely than not it's in a raw(er) format. This means the video card must do more work. SO, this video card is a great buy and a good fit for the system, the issue may be that you are either having codec issues (yes, I know he's probably using mpg2 video, but it still requires processing), or not enough power from the PSU, or the single fact that you did not completely uninstall all of the old video card.
thanks I'm planning on putting a 550Watts PSU tomorrow and see anyway another question: Any idea why my video card would work with my 58inch Samsung HDTV via VGA or DVI (Dvi/Hdmi adapter) for display but NOT THE HDMI port? When I plug my computer at 1980x1080 display ... it'll work plugging with the VGA and DVI port but not the HDMI ... it say (NO SIGNAL)
Ah! That may be because HDMI can be an encypted format. Use DVI anyways, you'll get the same resolution on DVI. Both DVI and HDMI are digital formats too, so there is no real gain for using HDMI (unless you've got your monitor handling audio, but I wouldn't recomend that). Honestly, if you can format and reinstall Windows, I'd say do that BEFORE buying a new PSU. System formats fix sooo many issues when upgrading. Heck, when I get new ram I format, do i need to? Not really, but why not?
So today I went out and bought a new PSU Coolmax CXI-Series 600watts (+12V1/ 17A .... +12V2/ 18A) I took out my old PSU and put the new one in .... It now plays the 4.5gb movies but when I try to play the 8.5gb and up movies it would shut down and reboot again! I dont get it I didnt think I would need this strong of a PSU to just run a Sapphire ATI Radeon HD4670 512MB DDR3 which was only $69 not some badass video card or anything. I also dont understand how my old PSU 430watts with my old video card ATI HD 2400 pro ($49) would watch all these movie videos I have with no problem. New PSU 600watts plays the 4.5gb now fine ... but nuthing bigger so is it still the PSU? Do I need a 750 watts PSU?
Your computer uses the same amount of power for either file size so unless your power supply was making yout pc unstable and rebooting at other strenuous times this was not the right fix. It probably lets you add another 4670 later, however. Make sure you're using the latest version of your video driver/ media player. Also try a different video player... but I think Pizza-Da-Hut is onto the problem with the hdmi handshake.
I say take that big ass file and put it on a usb stick and play it on your laptop or someone else laptop or desktop. It could either be that file is ripped and coded improperly or it could be something like a computer software issue with your computer not liking the file. Try going into safe mode and play it. I also would uninstalled all codec and reinstall k-lite codec. If that doesn't work I would say to check your CPU and see if it's not overheating when full loaded. Another thing to try is to use drive sweeper to uninstall your video driver and install a stable video driver. This is more to do with software and driver conflict. What Operating system are you using?
