I have an ASUS P5B-VM DO motherboard, Intel Core 2 Duo chipset, four 1GB memory sticks and ASUS LCD monitor. My desktop computer was in hibernation overnight when there was a power outage for a few seconds. In the morning when I started the computer, the monitor says “No VGA’ (although it is connected to the DVI card). And I don’t hear the usual beep sound when booting the computer. Monitor and computer are not communicating.
The same thing happened about a month ago. Then I changed the CMOS battery (Lithium CR2032) and it worked fine since then until now.
What do you think is the problem?
Is my CMOS battery being drained out for some reason? If so, what is the solution?
Can you get any rechargeable CMOS batteries?
If I have to replace the motherboard, what will be a good replacement motherboard? ASUS discontinued this MB. If I have to replace the MB, it does not have to be micro or compact MB as I have a big SMILDOON RAIDMAX case although I do not play games on my computer. I found out that it is not easy to find a motherboard with 4 DDR memory slots (240 pins?).
