registry error repair???

[severous01]

i need a registry error repair program

i use avg freeware and spybot all the time, i love them, and have never really had a problem. i cleaned my pc the other day deleting programs and now every 20 min on the dot, my laptop crashes with blue screen of death.

i dont know what it was i deleted, but i dont wanna pay 50 bux for a registry cleaner, and it's not malicious software cuz malwarebytes woulda picked it up...or avg, or spybot.

any way, i dont do many sites other than this and gamefaqs any way...and wife does facebook. any way, any help would be...helpful. thanks
