I found this site googling my problem with my laptop. Im really new at this stuff and could use some help pls. I cant run my virus scan either on puter or online and cant update it either bc my puter shuts off during the scan. I cant do it in safe mode either. I read some posts soomewhere on here about ppl having same problem. Im using the AVG which i really like and i downloaded ad-aware (think thats the name) and system mechanic and they find the usual stuff and i do the deleting crap. No viruses found so i know thats not it. Just started doing this the last couple weeks. I also downloaded speedfan which i have no clue how to use, lol. Could someone pls tell me how to use it and also i read somewhere about cleaning the fan(s)? Can someone tell me step by step how to do that so i dont wreck my puter bc im really not that smart with this stuff. Im hoping to fix this stupid problem. Thanks, Brat.
