Sometimes when I switch on my computer, instead of the normal 'beep' sound heard when bootin up, all I hear is 1 long beep, followed by short ones. The CPU then jus stops booting and freezes, and my monitor goes into standby. I usually have to switch it off and wait for a period of time b4 I can try again. It may work normally or it may jus do it all over again.
This problem pops up only intermittently, I cannot even guess when i turn on my PC, whether it will start normally or not.
There is also some additional problems that also occurs internittently. When I go into standby mode, the PC will sometimes not be able to recover safely. It jus freezes up. Also, the monitor sometimes flashes, and then goes into standby then the cpu freezes when i am using it.
