Wanting to upgrade my graphics, but not sure what's right for my PC

I got my computer 2 1/2 years ago, and now it's becoming an issue with gaming. I'm sorry that this will be a little long, I want to give enough detail so you all can understand enough to hopefully help me figure out the problem.

I play World of warcraft and 3 months ago my computer would act up after a while where the monitor would turn off/go to sleep, and I'm unable to get it back on, and my computer would act as if it froze. I'm not 100% if it does, but I have to do a hard reboot to get the monitor to turn on again.

Lately, the last 3 days, I tried WoW 2 times and that same issue would happen... I then left things alone, turned off the computer for the night and when I woke up the next day, I tried to turn on the computer, but nothing happened except the blue light on the power button would light up (the green lights inside would also turn on) but the monitor would stay off. I managed to get the computer on by holding the power button for a few seconds then let go, then the monitor would turn on and the number lock light on the keyboard would turn on.

I even re-installed the computer thinking that would solve my problem... It seems to have worked to some extent , BUT the same thing with turning it on, happened (wouldn't turn on at first) and that was 2 days ago. Now, after updating all the drivers ect, the computer seems okay. I am still unsure what went wrong. I haven't installed any new hardware or anything. I'm thinking it could possibly be a graphics issue, but not too sure. The graphics is the integrated Raedon HD 4200.

The weird part of the issue is the fact that the game would be the only thing causing the computer to act up. I can browse the internet, watch movies, play Left 4 Dead, use Sony Vegas and nothing would happen. But when I play WoW, it acts up after a minutes (sometimes I can play for an hour or two, or longer if I'm lucky)

my computer is the HP Pavilion p6750z,
Operating System: Windows 7 Home Premium 64-bit
Processor: AMD Athlon(tm) II X4 640 Processor (4 CPUs), ~3.0GHz (( Front-side-bus (processor dependent) Up to 5.2 GT/s)
Chipset: AMD 785G
Memory is 3 GB,DDR3 PC3-10600 (messaged as PC3-8500 on the 250 processor)
HDD is 500 GB, 7200 rpm, SATA 3G
DirectX Version: DirectX 9 I think
Power supply is 300 Watt

I am thinking of upgrading the computer, or at least the graphics for now, (maybe the memory too) but I'm not sure what one to get that will work with my computer.

I think that's all the main detail I can think of... if you have any questions, I can try to answer them the best I can, I'm not too great with computers.

Your 300W PSU won't allow any decent gaming card. I suspect you won't have physical room and proper cooling in the HP case either. Consider building a new computer...

"the game would be the only thing causing the computer to act up. I can browse the internet, watch movies, play Left 4 Dead, use Sony Vegas and nothing would happen. But when I play WoW, it acts up after a minutes" --> either the PSU is dying, or you need better cooling. Download and install speedfan and see if your graphics card is overheating under load.
