As you can see, the utorrent suddenly appeared on the lower part of the screen. I've been using the PC for 3 days and it happens sporadically, but my mom bought this computer last year and she said she started experiencing this a month after she bought the computer. She didn't take it as a serious problem since it doesn't happen often, but it bothers me since I'm used to using a smooth-running high-end PC back home, and I told her she should have told the problem anyway while it was under 1 year warranty. Aside from that the overall speed of the PC is sluggish at times, especially when watching videos (including video streaming such as Youtube) where the frame kinda freezes for a few seconds. And no, it's not the internet connection because like I said it happens even when I'm watching some already downloaded videos. Strangely though, I can play some games just fine. I've been playing Maplestory here with no problem at all lol.
Here are some things I tried. I checked the video card driver version to see if it is updated and it seems the cd driver that came along with the video card matches the one on Nvidia's website. So I uninstalled the driver and removed the video card thinking that it could be defective and used the integrated video card of the motherboard and installed its driver using the cd that came along with the motherboard. Same problem when watching videos and after 40 mins of internet browsing, the screen problem occurred. I guess it is safe to assume the video card is functioning properly. And yesterday I took a drastic move of reformatting the computer but the problem still persists. Now I can only think that the problem could be with the processor or memory, but I don't know how to test these so I need help on this matter.
This is the spec of the computer.
Motherboard: Biostar N68S3+
Processor: AMD Athlon II X4 640 3.0Ghz
Memory: Kingston 4GB DDR3 1333
Graphics card: Nvidia GeForce GTX 550 Ti 1GB DDR5 192bit
PSU: Generic 600watts
DirectX version: DirectX 9.0C
Operating System: Windows XP Professional SP3 32 bit
2 fans (1 blowing in and the other 1 is an exhaust) and a standard casing (not the flashy gaming type).
Any assistance will be greatly appreciated. And sorry of the tldr post.
