Is My r4 card a fake?!?

When i bought my r4, and tried to extract 15 games from winRAR and only 3 games worked. It always says winrar diagnostic info: it is either corrupt or had an unexpected end to the archive. is this a problem with my r4, micro sd, computer, winRAR, or internet connection? (cause it is very slow) I have the newest r4 software v.1.18 or something. to pts

My windows partition on my macbook pro was playing up (unexpected restarts, blue screen of death then a restart, stuff like that) i tried using a file registry cleaner and it found problems with my registry every 5 minutes.This certainly wasnt due to a virus because i had antivirus software (AVG) and the only sites i went on were ones to get software such as skype and itunes. So i reinstalled windows, reinstalled all the games and all the software, just one day after the reinstall it gave me the blue screen of death again, any ideas? because im entirely out of them. 🙁

P.S. ive also tried to repair this disk both with the mac ‘Disk utility’ and after restarts windows starts a disk repair thing too, neither seem to have had any impact.
Thanks in advance any help is appreciated.

ok i reinstalled xp, cleaned the registry keys up, defraged it, did the disc clean-up, upgraded the ram from 512mb to 1gb installed and ran norton anti-virus, and theres nothing on it to slow it down. why is it running so slow on the internet and games online?is this a bad graphics card problem or what?

I want to play the game Timeshift but all my video card and other computer system drivers are horribly out of out of date . Is there any site that i can go to so that i can scan my computer and find out what driver downloads i can put on my computer to bring it up to date and make it faster and make the games stop freezing . I need to have a site that does not have an unknown publisher and is a reputable site. Are there any sites that do the scan and update drivers so that i can get my computer in tip-top shape?
