The first problem that I had with my PC was when I received a statement when I tried to turn ON my PC "A Bootable Device has not been detected". I was able to fix the problem when I searched for some answers in Google and I came across this site. This was the Link that helped me: http://www.bleepingcomputer.com/forums/topic38965.html... Luckily everything went smooth for a couple of days.
After a week I tried turning ON my PC and somehow my Monitor doesn't display anything at all.
I tried Removing the CMOS batt, RAM and even my VideoCard. Cleaned them carefully with a brush to remove some dust and putting them back to their specified slots. I have 2 2GB RAMS for 2 slots so I tried switching their places. Nothing seemed to work from what I tried to do. Then I removed my VideoCard and plugged my monitor on the built in VideoCard and suddenly it worked. So I thought at first that maybe my Videocard was the one causing the problem. Somehow after I shut down my PC, when I tried turning it ON once again after a couple of hours, I encountered the same problem. I thought this moment that maybe my monitor is the defective one. Then I tried putting back my VideoCard and plugged in the Monitor with it, it started to work again. Now it seems that I'm dealing with a problem wherein I would keep on switching from my VideoCard to my built-in VideoCard every time I would turn ON my PC. Restarting the PC would not affect though. It would only happen when my PC would be TURNED OFF for a couple of hours.
I re-formatted my PC for this cause and installed the proper drivers with updates. But it seems that I still encounter the same problem with switching the Monitor Cord to each of my VideoCards. I don't know if resetting my CMOS to default could have caused this in reference to the first problem that I encountered.
Now I don't know what to do. I hope someone here could explain to me the cause of this problem and tell me what to do to resolve this issue.
