I'm having an issue with my COMPUTER.

First off, specs.


Windows 7, 32 bit.
500g Sata HD
Dual core 2GHZ processor
4gb RAM


Anyways, this happened late last night when I reconnected my modem to my computer (after having had it out plugged into my Xbox360 for some Xbox Live). Webpages were appearing coded, or gibberish. Some graphics/videos requiring Flash Player were not showing. Thinking it was a flash error, I uninstalled it and attempted to reinstall. Google Chrome would not let me download it. Neither would Firefox or IE. It NEVER gave an error message or anything. It just....never downloaded. So, naturally, I thought it was my browsers. Uninstalled all but IE, and upon attempted reinstall of Google Chrome, I got an error to the effect of "Authentication Validation failed". And the download timed out. Mozilla downloaded the .exe launcher, but upon launching it, force closed due to an error regarding an expired/faulty "Digital Signature". Upon some more testing, NOTHING web based will download. And, on the rare occasion it will, the .exe installer wont launch. Attempted this with Windows Live Messenger, Skype, iTunes, Google Chrome, and Mozilla Firefox, as well as Adobe Flash 10.1.

Did a complete reinstall overtop of my current partition to no avail.

Did a FULL partition deletion (resulting in the loss of every song, game, and document on my computer) and reinstall, also, to no avail.

Help?You did a complete reinstall and you still have the same problems you describe?

DId you "repair" or did you format the disc?

If you formatted, did you zero the disc? (long format, at least)

If you completely zero a disc and install an OS from scratch, there's no way something can be carrying over. Have you disconnected all other drives and see if your symptoms remain?I'm not terribly sure what you mean by that.

From the installer for windows seven, it showed my previous partition as used space. Clicked it, and it gave me the option to delete it.

I did so, and then created a new partition.Okay. So you deleted the partition and created a new one and reinstalled the OS. Now what is the exact NATURE of your current problem?Any web based download (i.e. something being downloaded through a web browser, Google Chrome, Skype, iTunes, Adobe Flash 10.1, and the like) are quite simply...not downloading. Depending on which program im ATTEMPTING to download ill either get varying types of error messages, or none and it just refuses to download. On the rare case that I CAN download the launcher info (In the case of Mozilla) As soon as I execute the launcher, it gets an error to the effect of unknown publisher, faulty digital signature, and so on and so forth. In short, I cannot install needed programs for some reason.What version of Win7 is this ? ?

Where is the DVD from ? ?
