My wife's laptop started acting funky today. When we start it up it will display the MS Windows XP screen like it is trying to load it up as usual. Then it will make a ugly noise, flash up a blue screen with an error message and restart the machine. Sometimes, it will just keep looping through this cycle. Then for some reason it will actually load up XP and it operates normally. I would guess 1 out of every 5 restarts it works. Then other times it will take us to a page with options to start in various safe modes, under the last windows config or just a normal startup. The biggest problem is when this blue screen 'dos like' error message flashes up it is too quick for me to capture. So, I don't know what to look into as the problem. She is running XP SP2. The machine is a Dell Inspiron 600m. She hasn't installed anything new on the machine in quite some time. I'm not sure what else to add so please let me know what other helpful information I can add.
Otherwise, any advice on how to track down this problem would be greatly appreciated!
