Resolved Power off no warning

My Pc has started powering off with no warning. There are times where I hit a webpage and it turns off also. Alot of the time it just turns off when you try to resume from a locked session. If its any help the os Im running is windows 7, in lavalys everest the cpu temperature is 43, cpu diod is 49, mobo is 27 and hd is 31 so dont think its and overheating problem. Any help would be greatly appreciated cos I need my pc for the work I do

 

Yeh thats what i'm hoping but thought I would seek some further advice I do have another one but its 24 pin header and my board only supports 10 so waiting on a lead to convert 24-20. Thanks for confirming this for me though the psu is about 5 years old now so guess its had its days

 

Ummmm, I doubt that. 20 has been the ATX Form Factor standard for the last 15 years, with 24 coming in only in the last couple years. And with the majority of 24-pin PSUs, the last 4 pins can 'break-away" into a separate 4-pin and 20-pin connectors, or even just hang off the end of the 20-pin motherboard connector.

There are many other things that can cause your problem. Heat is a primary, but I agree, your temps look fine. Failing RAM, failing CPU, or failing motherboard can too. Leaky capacitors on the motherboard can cause sudden crashes, reboots, or power offs. You need to inspect them carefully.

But, the first place to look in almost any hardware issue is the PSU - you must make sure you are feeding good power to the system.

 

lol 20 sorry typo! and now it make a groaning noise so think it is losing power.

 

Well, groaning noise could be bad bearings, or the transformer, or something else. But the same advise applies - I would start with the PSU.

 

I added the new psu but now no on screen graphics any ideas? Im posting with psp atm

 

I have filled them in but no show @ specs. All cables are intact and card is secure.

 

Greater last was 350 new one is 450.

 

Thanks Ill give it a go

 

Yep working fine with old psu back in so maybe fault in new psu what do you think?

 

Looks that way - assuming all the necessary plugs with the new PSU were securely connected the first time around.

 

I will get another one do you think it will be safe getting a higher capacity then and thanks again

 

Sure. Understand a computer draws what it needs, regardless if the PSU is a 450W, 650W, or a 1000W PSU.

 

Thanks all working now problem resolved
