So I press F2 and the computer tries to do something but then I get a blue screen, so I turn my computer off with the power button and the next time after I hit F2 I hit F8 for advanced startup options and select start my computer normaly and then I can get on.

Also, when I start my computer, I get this anoying thing that pop-ups and says a key component wtk kernel is missing. The computer is also extremely sluggish and randomly shuts down. The time and date is also wrong and sometimes the screen randomly doesn’t turn on for a period of time, so I replaced the Cr2032 battery because I though there was something wrong with the BIOS, which I got a message before saying there was. I also put the BIOS settings back to the Default settings (and saved them) but it didn’t do anything.

Also, I orderd this virus protection from Verizon but it won’t download because theres an IE error. Speaking of which, I keep getting these certificate errors for almost every page I go on online. I also download hiijack this heres my log file if it helps…

Oh yeah one more thing… I tried to do a system recovery because my computer is inpossible and I don’t have that many files on it and I don’t mind formatting the drive, but then I got this message:
STOP: c0000218 {Registry File Failure}
The REgistry cannot load the hive (file):
\SystemRoot\Ststem32\config\SECURITY
or its log or alternate
It is corrupt, absent, or not writable

So, I am totally stuck, I just want a working computer. Someone please help me… All these problems just recently started. Its always been kinda sluggish though. Please help…
