I have this strange problem which I hope you people can shed some light on.
In short : My pc wont start up properly. It will take either 1. some 20 minutes before the screen will come on (and it would give the wrong screen-resolution) or 2. (in most cases) the screen wont turn on at all. In the latter case, if I will power the pc on/off for some 20 times or so, the screen would finally turn on (in the proper screen-resolution). And when it finally does come on, I can use this pc without problems for hours on end.
What I did :
- flashed the BIOS
- updated graphic and monitor drivers
- changed monitors
- changed graphic card
- cleaned the fans
- replaced cables
All to no avail.
I haven't reinstalled Windows or checked for virusses because this problem seems to happening pre-Windows and possibly even pre-BIOS?.
When this problem occurs, the power-LED from the monitor would blink. And during this problem, a very high-pitched and very faint beep is heard..I couldn't trace where it is coming from (possibly the mobo?)
My setup is a : ASUS P5G41T-M LX, Intel E5700, 4GB DDR3, NVIDIA GT218 (tried other videocards : same problem)
Thank you in advance! :-)
