Hello everybody,

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! :-)

I dont think it would matter. The problems always occur immediately during starting up..so when its still trying to get through the "BIOS"-screen.

If I had to hazard a guess it may be the PSU. They do sell PSU testers and if you have a multimeter it can be done manually. PSUs can test okay but when under load fail.

Have you tried the integrated graphics on the MB vs using the discrete GPU?

I had a similar problem and it turned out to be the monitor failing.  Eventually failed to power on and had to get a new one.

When I come home, I will try another PSU and also the onboard-graphics option and will let you know, thank you :-)

Wow... I think I answered you in a polite way why it would not make much difference. So why respond like this? I do appreciate your help but my problem happens before it even reaches Windows so Safe Mode would not make much difference..if I will even make it to that point.
I still have no idea why you have to respond in this manner. I dont have all the knowledge like you guys are having here (thats why I came here) but now I feel a bit uneasy to ask for help, so thanks

Check your UEFI/BIOS settings. You may need to enable the onboard graphics. Some motherboards can switch automatically. I would switch the PSU with the Nvidia card in place before using the onboard graphics if you have a spare PSU.

Dear JohnC_21,

I indeed replaced the PSU and now everything works like a charm again, so thank you for your time and help :-)

@mjd420nova : after changing the PSU which solved my problem, I still heard that faint beeping noise I was referring to in my first post. That was my monitor causing this so I replaced it as well. Thank you as well for that tip :-)

@mikey11 : thank you for your help as well, no hard feelings please :-)

Glad you resolved it.

 

We don't normally close topics.

 

Happy computing :).
