blue screen of death -_-

installed photoshop cs4. intallation went well (or so i thought). i opened it and it worked! until the next time i opened it which resulted in the blue screen of death. and the time after that. and the time after that.

so i uninstalled and reinstalled again. and the first time it worked! until the next time i opened it.

so i uninstalled once more and installed the trial version because i needed to use it and didnt have the serial number on hand. and the first time it worked, but the second time....you can guess.

so now i have a trial version of photoshop cs4 on my laptop (windows) that gives me blue screen whenever i open it. i attempted to install photoshop but it didnt give me the option to put in a serial number or anything. it said it worked but im pretty sure ive still got the trial. which doesnt do me a lot of good because it gives me blue screen.

any thoughts, suggestions would be much appreciated!
