Can I update my graphics card?

Take the side off the computer and take a look inside to see which slot/s are there, you may find this helpful in identifying which your system has:

While the side is off, also take a look at the PSU, post back with the outputs on the rating label, although I suspect it will be very low 
Also post the rest of the specs: Exact CPU, memory, case type- is it a normal ATX or slimline? and monitor size and resolution.

ok, I will open it up and take a picture because to be honest I don't know the exact CPU type and other things that are needed so maybe you could identify the perfect video card or equiptment that I need to upgrade it....

Ok I got some pictures, and the information from CPU-Z as you requested here they are...

So is it possible to upgrade or not  

on cpu z on mainboard what does it say in graphics interface

250W PS I believe.


Finding a decent card to upgrade to with that will be.....irritating.

it dosen't say anything its just whited out :l

so now what do I do guys??

Looks like it supports PCI Express, you probably will need a new power supply though.

@ ultraslan1988: The MB has a PCI-E x16 slot, so that's OK.
Take a close-up shot of the PSU label, I can just see the ratings below the FSP logo but cannot make the figures out.
Why the upgrade? The reason I ask is that for HD or even normal video playback you can install a HD4550 (ATI) or 9400 (Nvidia) without problems, right now and see an instant improvement, but for games the upgrade will need to be more powerful, which my require a PSU upgrade.

The PSU is only 250W, that's why I am so limited I guess I just want the upgrade to play the occasional game and to run a more advanced video editor the current one I have isn't very good.

I don't have much of a budget, only £40 so I will probably spend most of it on a a video card and the rest on a PSU. would 400 be aequate enough to run ga
mes like battlefield 2 and GTA 4??? here are the ones I am thinking of buying....

any feedback would be appreciated...

I do not think either of those PSUs are suitable, they're both unknown makes and neither has a 8-pin motherboard connector, which I think you'll need-I would VERY strongly advise you to avoid them like they had the Plague and Man Flu.
The HD4650 draws a tiny amount of power, directly from the motherboard. I would say that it would run on your existing PSU (at maximum draw it takes 40Watts-less than 4 amps). It might run BF2 and GTA IV but it is a low-end card, do not expect it to run them at high settings and resolutions.
Ignore the 6200, you'd be better off sticking with integrated.

can you give me the link to the graphics card then please? because I searched it up and it says that it needs 400 Watts =/ I don't mind if it dosen't play on maximum settings as long as it works
