Other than that, liek mentioned before, fire up that install disk, and try a startup repair, or a quick restore from a few days ago, if you have that feature on.
Definitely, the best solution is this.
If you have done something that is clearly not recommended for years now (installing two anti-virus at the same time, even though in your personal experience it went well up to now), I wouldn't even consider the overclock as the culprit in the first place.
A good idea is to always have a Linux disc nearby, something like Ubuntu, it has has the ability to boot directly from the disc itself. If it boots normally and you can go online and work normally in Linux, you have already sorted out that it's not the overclock, but the software mess you just did with two anti-virus programs installed.
Anti-virus software has entries to start scanning even before the OS screen loads up, so it can catch some nasty viruses that go deep into the OS, that must be removed before they can reinstall themselves into the main memory on each boot-up. That is probably why you are probably having problems booting, and the reason it is not recommended to install two anti-virus programs side by side.Edited by tpi2007 - 3/6/11 at 9:20am
