1st start up: OS loaded up slowly and was sluggish when it finished. Used the power button to shut it off.
2nd start up: OS didn't load at all, stayed at the blinking line and I couldn't do ANYTHING because no matter what key combo I did, it would make weird characters.
3rd start up: Currently running memtest.
This is the first time EVER that it's done this.
Intel Core i5-2430 CPU @ 2.40GHz and 8099 MB of RAM, so, I SHOULDN'T be having these problems. =/
