Computer keeps freezing tried malware area already

I just spent last few days in the malware threads with no luck. The person who helped me said he thinks its not a malware problem so i should post in the hardware/software areas. Im stumped. I havent added anything new to my computer. I use PDMarg Recorder 5.3 everyday to tape favorite Sirius radio show and the covert files to MP3 with BladeEnc 0.94. Recently BladeEnc stopped working giving me error saying:
Run-Time error '62':
input past end of file

This all started happening when my computer started freezing on firday afternoon. I dont know what do now?

Heres the malware thread link:
