Right well you see the problem is that when I'm streaming a video or downloading an mp3 or picture. With the video, while im watching it, it stops suddenly but the rest of the video carries on being downloaded but my pc acts as if it is the end of the video. with an mp3 when i download it there are always tiny glitches in the mp3 sounds where it goes squeaky but when i download it on my dads laptop it comes out fine. the same with the pictures. also everytime i download an exe file there is always a bit currupted so i cant use it. if anyone could help me out i would be most thankful,

Hello Zornsthorne Welcome to PCHF

It sounds to me like you may have a hardware related problem. It seems like you are receiving many bad bits of data while you transfer data over the internet. The obvious problem would be a faulty network card, but it may definitely go further than that. Possibly a defective motherboard. I would first try replacing the network card.. They are pretty cheap, and if you buy from a store like Best Buy or Circuit City, you can take advantage of their return policy if replacing the network card doesn't help.

You can also follow my prework link and post your results in the HijackThis! Logs section of our forum for a Security Team member to take a look to see if it is possibly malicious software causing the problem.

Hope that info helps you!

is there anything else it could be (even the most remote chance) so i dont go out and buy these and then realise its something else..?

Well unfortunately, that problem is a very tricky one to determine. As a technician, that is the kind of problem you solve by trial and error.

In order of complication (least to most), you would first do a full virus/spyware diagnostic or try just replacing the card (takes about 5 minutes and you don't have to mess with your operating system). If either virus/spyware removal or replacing the network card doesn't help, then the next thing would be is a repair installation of Windows. If that doesn't work, then a full restore of Windows. If it still produces the same problem after that, I would suspect a faulty motherboard.

Well, the very first thing you would do is check your device manager to make sure there are no hardware conflicts and your drivers are installed correctly, but I'm assuming this just recently became a problem and everything was working fine before. If the problem happened JUST after you installed some hardware, it is possible there may be a resource conflict. Also, you may want to run Memtest32 (click my link below) to test your memory for errors.

That is about all I can think of. So do it in this order:

1. Check Device Manager (Control Panel -> System -> Hardware Tab -> Device Manager)
2. Run Memtest32 (click my link below)
3. Run virus/spyware scans (click my prework link below and post in HijackThis! Logs)
4. Replace network card
5. Repair installation of Windows (backup all important data FIRST and make sure you have a legal license of Windows cause it may ask you to validate your Operating System before using)
6. Full restore of Operating System
7. If all that doesn't work, most likely bad motherboard

I'm pretty sure that is the extent of it. If I'm missing something, someone fill in a blank.

Hope that helps!
