Hi everybody,
I posted this on another forum previously, but so far I couldn't get a solution, so I wanted to ask you too. I hope that is fine.
I recently installed a new fan and heat sink to my HP dv7 notebook and now have problems with my graphics card and the Internet connection.
A short explanation of what I did:
The fan was sounding very weird for quite some time, so I decided to replace it. I took my whole laptop apart, until I got to the old heat sink. I took it off, and cleaned the CPU as well as my AMD graphics card with some 70% alcohol until all the thermal paste was gone. I then put the new heat sink and fan in. There was pre-applied thermal paste on the heat sink. I made sure everything was nice and thigh and continued to close the laptop again. At the very end, I made a little mistake and by accident put some pressure on one of the two cables that were connected to the wireless card. The cable was a little deformed, but I was able to form it back into its original shape (I couldn't plug it in anymore at first, but when I shaped it a little bit it worked again).
So I turned the PC on, and this was when the problems started. Here's a short description of them (In the order in which I assume they should be solved):
Firstly: The Internet connection seems to have problems. But it's not that I can't connect to the Internet at all. If I use my browser (Opera) or want to check my emails, the connection works just fine. However, Windows reports that it cannot connect to the windows update (can provide error code if needed). Also, I noticed that when I try to for example add a contact in Skype, it will tell me it doesn't have Internet connection, although for the rest (i.e. calling somebody) it does obviously have connection.
The wireless adapter shows in the device manager and doesn't have to experience any problems.
Second: The graphics cards have a problem. I am using a switchable graphics card system (one graphics card is a Intel Graphics Family, the other one an AMD radeon card). From the very start, the resolution is on 800x600, which I cannot change. In the device manager, both drivers seem to have problems. The Intel one displays: "Windows has stopped working this device because it has reported problems (Code 43)" and has a yellow sign next to it. The radeon card displays "This device is disabled (Code 22)". Right after the start, I also get the message that I do not have an AMD driver installed (which I clearly had before I took out the old heat sink). If I disable the switchable graphics card option in the BIOS (i.e. I set it to fixed), I only get a black screen. Obviously, since I still have a display, there is something working, otherwise I would have the same black screen for the dynamic system for the graphics card. However, in dxdiag, there is no card selected that is managing the display right now (which confuses me a little)
I'd greatly appreciate any help or idea on what could cause this problem!
Thank you so much for reading.
