A few months ago the motherboard in my laptop went out. I purchased a new-ish one off ebay and replaced the board. For some reason, the new mobo didn't recognize my hard drive, so I had to do some voodoo to get that to work. Ever since this incident, my viewer (Firestorm) has been running terribly slow. I get maybe 1 or 2 FPS in a busy sim, and maybe 10 or so in a not so busy sim. Lagg is absolutely horrendous and even affects typing in IM and local chat. Occasionally the screen will flicker black and Firestorm will not respond. Should I replace the hard drive? Or is it time for a new laptop altogether? My laptop is an older model Dell XPS M1530 that I built myself back in 2011. My specs are as follows, at least what I can remember off the top of my head. Dell XPS M1530 Win 7 Ultimate 32-bit 2.2ghz Processor 4Gb RAM Nvidia GeForce 8600 GT
