Uh-oh. When you did the install--you should have been offered a media check, did you do that with all of your CD's?
I had all sorts of problems with an install and found that the windows had corrupted the download. Then, I also had another problem because I hadn't burned the iso as an image. So, windows opened up the iso, burned the files and corrupted them.
I hate to say this, but the install sounds like it is hosed.
You may want to put together a hardware list--the different chipsets within your computer, in case the install scripts/engine didn't detect them properly and manually select them during the install (or re-install). If you have "cutting edge" video cards, or anything which isn't on the Hardware Compatibility list, you may have some problems.
If you have windows installed you can get that information in a few different ways. It depends on what you are used to. You can go to the hardware manager and write them down by clicking properties of each device.
The advanced settings on the monitor will give you the horizontal and vertical refresh rates--you do that from the control panel--display--advanced settings. You can google the display and look up the specs. for it to get the ranges (ie. 51.5-150Hz etc. Write them down or print it out. You won't remember. Believe me.).
[Do you remember if the installer picked the exact manufacturer and model of your display during install? -or- give you the choice for it? I hosed everything up because I didn't double check what I clicked--I was lucky I didn't smoke my monitor.]
The system information tool (in windows) will give you the specific north and south bridge chipset information as well as the video chipset and ethernet chipset if you didn't get them from the properties buttons. Write all that down. And the specific sound card information.
the chip-set information and check the RH Hardware Compatibility List for your version number. (RH-9 or such.)
Of course, in my case, after spending all of that time doing all those things; the re-install went in without a flaw. (And I didn't need all of the information) That hurt.
You should check that stuff anyway--really.
Since the install appears to be hosed, read up about partition layout and stuff, there are a lot of options open to you. It is very nice for Imaging and/or back-ups and recovery, if you have more partitions for linux than "/" and "SWAP".
