i don't see how this thread is fail, he posted it in the tech section along with tech related problems.
unless by fail you mean his computer continuously getting BSOD, trojans and something eating up his ram.
and you do lose ram by viruses, if not through them. trojan downloaders, as an example, downloading large amounts of useless data, writing it on the HDD which uses RAM/CPU power,etc.
spice, if you're still having huge problems with your computer, i suggest posting your problems on a more tech savvy forum along with a Hijackthis log if you want to remove viruses completely. also your computer would probably shutdown due to low RAM.
also, open up Task Manager (CTRL ALT DEL), go to the processes tab and click on the Mem Usage tab. if there's anything suspicious, search it up on google, especially the ones that are using a large amount of memory. make sure your computers idle while you're doing this.
