ok heres what happened. my computer froze (nothing new) so i turned my computer off at the surge protector (nothing new). while it was off i decided to open it up and clean it out with some canned air (nothing new). when i rehooked up my wires and went to reboot i hit the I/O on the back on accident. when i turned it on it gave me a prompt to run windows normally. i did then it restarted. i tried to run it in safe mode and it did the same thing. so i made this post off my psp. HELP PLEASE!!!
if you get a SYSTEM\WINDOWS\SYSTEM32\CONFIG error message or something like that i cant remember what it is exactly and says select r at the start screen then you are going to want to make a slipstream disc if you have service pack 2 installed it gets harder but what it is a CD with a recovery prompt on it and you have to put in the fixboot command and then it should work but you need to get a registry cleaner too.
as soon as i do anything on the prompt screen it loops back to the same screen after a restart. I pretty much cant do anything on it.
I had something like that. When your computer starts going into the loop, turn it off, and come back 15 minutes later. If It turns on normally in 15 minutes, then you probably did something to damage the power supply. Also, if your computer starts making a high-pitched noise, then it's defiantly the power supply.
