I have a Multicom Kunshan X7200 laptop. It's a custom built laptop from Norwegian manufacturer Multicom
. Specs are:
Intel Core i7 980X 3.33Ghz LGA1366
Samsung 4GB DDR3 PC1060 1333MHz
Nvidia GeForce GTX485M
Unknown Mobo, sound card (probably built-in)
Connected through the web through network cable
Win7 Home Premium.
Now to the problems: Sometimes, when using sound for anything (gaming, music, movies, youtube, etc) the sound will become choppy/crackling and distorted. This happens both when I use the laptop speakers and my headset (Koss SB/45). The only solution is to reboot. It'll work fine for a while until it starts crackling again. It can happen right after boot or it can work fine for a day or two. Updating the sound drivers from the manufacturer didn't help.
There is also a video problem, that occurs less frequently, but still annoying. My screen will go black and then flicker for a few seconds, and then return to almost normal with the error message: "The screen driver malfunctioned and shut down, but has now been restored" or something similar to that. When I say return to almost normal it's because sometimes there's a pink-ish ring on my desktop (does not show up elsewhere) and some buttons, tabs and menus are weirldy colored. A reboot fixes this. Once the driver has started crashing, it will do so frequently (as in once per 5 minutes to once an hour) until reboot. The error seems to be random, as it can happen while the computer has been idling for an hour or during gaming. However, it may be just random, but it seems to happen more frequently while surfing the web with Firefox (haven't tried any other browsers). Updating drivers seems the most obvious here, but the ones supplied by the manufacturer website didn't help, and the Nvidia homepage won't let me download. Nvidia tells me to contact the manufacturer.
I've been in touch with Multicom, and their solution is to do a full reformat. If not, I'll have to ship it back to them for testing (which'll cost a fortune). I'm ready to try some advice from you guys first.
