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

hi, i heard of perfect optimizer that can help my computers errors and make it run faster and help my computer to be more protected but i gotta pay for it. is there any other software out there i can download for free that is well known not like something no one has ever heard of that i can use to help my computer i have a windows vista 32-bit.

What is a good computer claening software.

Such as a good registry cleaner and optimizer.

U usually use ace utilities but my subscription is expiring and I want to know if theres anything better before I buy again.

Thanks.

I need something that does it all; ie, registry cleaning, virus targeting,problem-solving,speed-incfreasing,garbage-removing,et
. Kinda like an overall optimizer..
