The cooling part of my old desktop was down so I moved the os drive ssd and a storage hard disk into my alienware. I removed my alienware OS drive so I can actually reboot my computer from my old os drive (I cannot set priority in BIOS without removing the original Alienware OS Disk). Currently my pc works fine but it apparently has lower fps in games and the screen will sometimes have glitches when I try to swtich tab in my chrome: it blacks out for a .5 sec and flash back to normal. Any idea what cause this and suggestions to fix this? great appreciation.
