registry cleaners????????????

Which registry cleaners can repair the blue screen error that is free to use? I have already used ccleaner and that doesnt work and perfect optimizer is not free

Anyone know where I can download the samsung sn-124 cd rom driver for free? I accidently deleted important system files using a freeware registry cleaner and now my cd rom driver is missing and it won’t let me do a system restore. I have tried uninstalling the driver and restarting and windows XP Home can’t find the driver. Here is the error code under device manager: "Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)"
That worked perfect, thanks!

Did the trick!

i mean totally free.not free to use then asks you to register to fix the problem.thats annoying and actually not free at all.

registry cleaners?

why do people always say that you should only use a MICROSOFT branded registry cleaner instead of any otther registry cleaner? and if its true then could you tell me a website for a FREE microsoft registry cleaner? if not, could you tell me a website with a FREE registry cleaner? ty

i cannot go to ANY websites that require me to download anything that will clean it. Nothing on my computer will update. I have AVG free and Spyware doctor. Tried cleaning registry and other startupfiles. HELP…..FREE
I cannot go to ANY of the websites anyone is suggesting but am able to go to any other website.
I have Firefox. However It does not open at all. I cannot restart my computer. Only shut it down. It used to erase my desktop backround everytime i turned on my computer. I fixed that. And after I left my computer so it can scan, It would have a message saying my computer is infected and would look like it was restarting but when I pushed crtl is started running.
