Hello, So I have a Gateway FX laptop which is running Windows Vista 64-bit. I decided to download the latest driver for my Nvidia 8800M GTS videocard. When I tried to install it, it said that I needed to uninstall my old driver first and then restart. After I restarted it, thats when the problems began. Now, occasionally, the laptop starts but the screen is completely black (no backlight) and and beeps a few times. Or, it gets to about the login screen and then turns black (backlight is still on) Or, it takes me to startup repair but turns black after a few miuntes (backlight is still on) Sometimes, my after my laptop screen goes black with the backlight still on, and it restarts itself automatically. I have read somewhere that it is an excess of charge that has been building up. I tried taking the battery out, unplugging it, and holding the power button for 60 seconds, but it did not fix it (Got to about 3 minutes into the startup repair screen before my laptop screen started turning black again). My heatsink/fan has also been malfunctioning recently, causing the internal temperature of the CPUs to average around 50-60 degrees when I am not playing games. I have never had a successful boot-up since. I am a freshman in college, and I do not have the time or resources to take my laptop to a hardware store and get it fixed. Any feedback on this problem will be deeply appreciated. Thank you.
