I don't know where to start, I have a satellite m45-s355 intel pentium m, 1.86ghz, 1024mb, 100 gb hard drive. When I turn it on a couple of times the screen was blank. But I guess the real problem is when it starts up and I click on a icon it just sits there sometimes up to 5 min. before it opens up. I have a wireless connection and it comes up twice and says it is now connect. There is a couple of min's. between the second time it comes up, it just freezes. I have run Regcure for the registery and it helped a little I guess. Sometimes I have to manually shut it down. I'm new to this so any help would be great.
