If the computer is having to "check for errors" nearly every time you start up then the failing hard drive is definitely a possibility. I would have that replaced, hopefully under warranty if you didn't buy it too long ago. As for the keys not responding, it could be dude to a driver malfunction, so the OS stopped seeing the "device" that has the buttons on it. Or heat could have caused the cables to sit wrong and not have contact with the PCB that has the buttons on it anymore.
I still think the hard drive is bad, and perhaps some cables need reseated.
ive been meaning to run the drive fitness test to see if the drive is failing.... I think it could be that too.
Another thing that i noticed about this laptop is that when you go to put the hard drive in it gets grabbed by a magnet. this seems very weird that they would have a magnet pulling on any part of the hard drive
also i saw this review on the newegg website "Pros: The specs are great and it's a very nice looking computer
Cons: It might just be a bad machine I got, but probably once a week the mouse disappears and the computer won't turn off, we have to unplug the computer and just wait until the battery dies."
It seems they have the same problem as me but didnt think of just taking the battery out to turn the laptop off...
also this review "Cons: my turbo button doesnt seem to work like everyone else says theirs does...
my main MAJOR con which i dropped 2 eggs for... is this..
anytime i play a game.. after about 2 hours.. any game that requires any sort of semi extensive G-card usage... it will freeze my computer.. in a weird way i suppose.. the game will still run.. and everything is still happening.. but none.. and i mean NONE of the buttons work.. i cant hold down power button... the only way to turn it off it to close it... and take out the battery.. and its soooooo irritating.. cuz you never see it coming.. there is no sign or prequil.. it just happens... and i dont like that when im showing off my super awesome laptop to my friends.. and it chokes like that.. very very very dissapointing.."
and this... "
Cons: Horrible, horrible keyboard; it's all cramped due to the numeric keypad being shoved in there, and the FN key is where the CTRL key always is, and that makes things even worse. The speakers are a joke. So have your headphones or external speakers handy when you need to play a game or listen to music. The BIGGEST problem is the keyboard-freeze issue: I've done some research on the web after I came across this problem 3 times in a week. Turns out this issue is common for a lot of people who have purchased this model. There's a good chance that a recently released firmware update fixes this, but good luck to people with low tech-skills. When the keyboard freezes, the only solution is to take the battery out, and that is not good on your laptop."
these are all for the gx-620 which is the same model as mine (MS-1651, mines just barebones)
Too bad MSI sucks for support.... When i first bought it if the laptop wasnt plugged in to the ac it would boot in 16bit color mode. I had to update the bios to fix this... I guess i might just have to flash the bios again.
lemme know what you guys think.
