Hello

Having a bit of a problem with my pc. Basically, my computer turns on but there is no display on the monitor. I fixed this by replacing the CMOS battery and this went good for like 2 months or so. The problem started when it happened again so I again replaced the battery. This fix only lasted like 2 weeks and now it's happened again. What I do at the moment to access my computer is take out the CMOS for like 5 mins and put it again. This seems to fix the problem but after a day the problem shows up again. I'm getting sick of doing this process every single day so I would like to know what is happening with my pc. Do you guys think this is due to a faulty mobo? Any help w...
