What is the reason i cant play 3d games on my computer ?

Assuming that your system requirement (RAM, video card etc.) is good enough for the game, you could try to update the direct X software and/or the graphic card drivers.

I see from your reply to stevieboi19 that you used to be able to play 3D games but one day, you suddenly can't, did I get that right? Maybe the video card is already worn out. Or, have you checked the system requirements of particular games and saw if your computer met those requirements? By the way, how long have you had that 3D card? If it still has warranty, maybe you can call the store/manufacturer where you purchased it.

Your computer's video graphics card does not have enough RAM to allocate to the high quality graphics of those games. Replace the video card with one that can fit the port of your computer, be it AGP or PCI Express. If this is a laptop, then your options are limited because laptops do not usually have a dedicated graphics video card.

You did not indicate whether you are using the built-in graphics card or a separate card. Also, you did not indicate whether you are using a desktop or a notebook. Most computers with builtin display card capable of 3D uses shared memory - i.e. it takes part of your memory for the display and the rest for running your OS and applications. This can be configured in your bios. When did your problem start? Is it after you receive a new patch for your application or a new patch for your OS. (Also not sure which OS you are using). Does any of your other 3D games still work or none of them works? If none work, then it might be somehow the driver has changed. Currently, don't have enough information to really advice you.

You pretty much answered your question with the computers error message. Your computer either doesn't have the video memory capabilities to run such games or your computer has too much running at the same time and can't handle it all to process the game but more likely the first one . If it's none of those then I think you'd need to supply more information for anyone to get a clearer idea .

I suggest by a video card it will solved your problem. I recommend Nvidia 9500GT for starter. Can run 3d games, online games, photoshop and cheap price.

It sounds like your current video card graphics are inadequate for the 3D games you are trying to play. Do you have a video card in your system or do you have onboard video? I don't know whether you have a laptop or a desktop but if you have a desktop then I recommend that you purchase a higher spec video card, something like Nvidia geforce. The video card will have it's own memory so it doesn't use up any of the ram in your system. If you purchase a video card it's likely that it will fit into your pci express x16 slot on your motherboard. Depending on the age of your computer you will either have a pci express x16 slot or an AGP (Accelerated Graphics Port) slot but not both. AGP is the older version slot. Anyway, I wish you luck. If you do decide to go for a video card purchase and you try to install it yourself check out youtube on how to install a graphics card as there are some good videos there. Andrew

I have the same problem except my issue occured once i formatted my laptop. it could be a issue with your drivers.
