So, you don't have an antimalware program then? Download mbam - http://www.malwarebytes.org/mbam.php update it, and do a full scan with it.
If you can't log on in normal mode then press F8 as windows begins to load and choose safe mode with networking and you will be able to downloaded it provided your computer is connected via cable rather than wireless.

The BSOD problem has absolutely nothing whatsoever to do with hardware. It was caused by tosdvdnt.sys which is a part of Spyware.EliteKeylogger which is malware.
@ Benmar, if you had bothered to look at the Mbam log you would have seen the problem instead of just guessing.
@ inwinter, have you used your computer to do any kind of online banking? Including the use of any accounts like paypal? If so, you need to change your passwords by phone as soon as possible. It is most likeley that the author of the keylogger you were infected with will now have all of your passwords!
