I'm having an issue with my HP pavillion G7. I've had errors in the past with the screen, which I replaced myself. The replacement was successful until a possibly unrelated CMOS error began to appear. I also had a bad battery which was replaced. The 502 cmos checksum invalid error appears at boot at times, once I reset it though it usually boots in windows and the clock is messed up. The computer usually would just turn on and display a blank screen. I decided to replace the cmos battery, but this didn't help.
It still is displaying the error, mixed in with a blank display at other times. I've also tried resetting the bios and updating it... but still no avail.
I'm not sure whether or not this is a hardware or a software issue. I'm willing to reformat my hdd if necessary.
Anyone have any suggestions on how to fix this?
