PC warning on boot up

Tregemred

Hi,

My PC has been a little reluctant to boot up for a while. I turn it on, the lights flicker and it goes off. I found it was better if I turned it off completely at the socket then tried again. Once the fuse blew in the power cable.

However, yesterday, DS turned it on and after POST, a warning came up on screen "H/W monitor status unstable". I went through the menus and showing red were:

Vcore voltage 4.16
3.3V 4.01V
5V 6.85V
12V 16.32V

I would really appreciate advice on this.

P.S. Use of PC banned until light can be shed on problem. Writing to you from creaking laptop

Sounds like your power supply is failing. Easy replacement job, should take you about 20 minutes. Just buy one of the same or higher rating than the existing one, eg if it's 300W, replace with another 300W or higher.
Deskktop PC's will use a standard ATX PSU, unless it's an older Dell, some of which used non-standard pin configurations.

Could be a resistor issue of somthing Motherboard based but as Macman says, PSU replacement is the only real home fic that is user friendly.

If it is not that, its a waste of money

Perhaps your the sort of person who would rather hand this to a shop for a diagnostic and repair? cost a little more but would be guaranteed work?

Do not get me wrong, replacing a PSU is easy enough if you want to try that as the fix.:)

Thank you so much for your prompt replies :beer:
I will try replacing the PSU, I guess if that doesn't help, then it's a new motherboard :eek:. I built it myself almost three years ago but I'm still on a learning curve with problems. I'm trying really hard to learn enough to fix things but am still standing on the shoulders of giants Wishing you a free lunch and a free laptop :rotfl:

Perhaps you could borrow a PSU and try that. Those voltages are scary. For instance, the 12V rail has a specified tolerance range of 11.4V to 12.6V.

Thank you for your helpful reply :beer:
The voltages prompted an instant ban on use until advice could be found. I haven't had time to source a PSU but I have a few "corpses" lying about. Later, I'm going to have a rummage and see what turns up. I might have something suitable to test the system.

Thanks again,
