hi, ive recently brought myself an ASUS X50R series laptop with vista home premium pre-installed. The other night I decided to download a Partition tool, because the laptop supposed to have a 160GB hard drive. I know vista takes roughly 10GB for the operation system, however in "My computer" I had 2 partition, one with 67GB the other 73GB. I then found out in control panel, in the computer management area I had another partition which was 8.5GB. so I downloaded this partition program and tried it out, no luck, so I went to uninstall and then the blue screen came up. I now cannot boot up the system neither in safe mode.I tried the recovery DVD which I also had no luck with. The message that comes up on the blue screen is:

STOP:COOOO21a {Fatul system error}
The session manager Initialization system process terminated unexpectedly with a status of 0xC0000024 (0X00000000 0X00000000)

How can I get the laptop back and running???

thanks for reading my essay lol.
