Desktop Computer Help Needed

[fuckwaffle]

I just booted my AMD A6 CPU with the fan turned off. It reached the desktop at 28 C (82 F) It shuts down at like 73 C.

If you boot up instantly at 54.5 C without it previously running, then something is very wrong.

Okay mister expert...I didn't say it was instantly at 129F, but it does get hot fast and if the fan didn't come on it would shut down long before the boot process was finished. And that's what we're talking about.

Did you turn off you water pump too?

My suggestion to Tony, check you fan and cooling fins.

merc, I've a degree in computer science and if I had to take the advice of any one person here, it would not be you...


You're too much like Obama, whose scant foray into "enemy territory" and classes on how to shake-down banks made him a business expert...

 

[fuckwaffle]

Yeah and nothing you're saying here matters. I'm not a pro but I've overclocked a few desktop computers so I'm experienced with PC cooling.

The fact is there's simply no way the OP's CPU can go from room temp to overheating in a matter of seconds during the boot process.

Could you point out where the OP said his computer shutdown within seconds?

Well dummy!

An hour is 3600 seconds, so no matter what he said, it can be measured in seconds!

Quit trying to STRAWMAN poor, honest expert merc!

Erm, yes it does get hot faster without a CPU fan.

And no, your computer will not go from room temp to emergency shutoff temp "long before your boot process was finished". There's simply no way that the metal in the heat sink can heat up that quickly. A room temperature cooler can absorb a lot of heat.

The CPU fan doesn't even do anything until your heat sink gets sufficiently hot.

Yes I can. And so could you two if you read the first sentence of the OP:

Symptom:

When computer is cold, during startup, it will suddenly shut down during the boot process.

Windows boots up in about 30 seconds on a standard hard drive.

STFU clown.

First, he doesn't say seconds, only that during the boot process it shuts down.

Yes, my i7 boots up fairly quickly, buy not in 30 seconds. It takes longer than that to get to the login screen.

And my laptop damn sure doesn't boot in less than a minute. It takes seconds just for the damn bios to load.

In all my years of working on computers, I have never, ever, seen one boot in 30 seconds. That would be 35 years worth of waiting for computers to boot.

 

[4est_4est_Gump]

I started my Vista computer in 2006 and I'm still waiting for it to stop loading...

Hey, I run Vista on both mine, I have never had a problem...except the one time Bill Gates download a Windows 7 patch to my Vista machine, that took forever to fix. Had to boot directly to DOS and do a restore point at the command line. What a pain.

Boot time is far more dependent on hard drive speed than CPU speed. The fact is that the CPU isn't pushed (making a lot of heat) until loading the actual desktop.

I just timed my A8 laptop on my call pone stop watch. 37 second boot time from the bios splash screen to the time the desktop appears. And that's with a sluggish 5400 rpm hard drive.

Regardless, the OP is measuring his shutdown time in seconds and there's no way he's overheating.

lol...


Maybe my Mac has a Vista emulator. All I know is that I have to sit the fucker on a fan or it burns my lap...

Don't block your computer's cooling system with your flabby thighs?

Sure...I believe you.

And like I said, I have never seen a computer boot in 30 seconds. You just proved my point for me.

Right there - "Windows 7 boot time: 34 seconds"

34 is not 30.

Y
Windows boots up in about 30 seconds on a standard hard drive.

34 is about that much though. And it's far too little time for a room temperature heat sink to go to blazing hot shutdown temperature. Sorry but you're just plain wrong in saying it is.

Symptom:

When computer is cold, during startup, it will suddenly shut down during the boot process. It is just like someone depressed the power switch on the front of the computer.

Things I have tried to resolve issue:

1) I thought it might be the power switch, so I purchased a new case and transferred all the components to the new one. That did not work. Same problem.

2) Maybe it might be the power supply, so I purchased a new one. Same problem.

3) Possibly it could be the hard disk drive, so I purchased a new one. Exact same thing happens.

When I turn on my computer, it starts booting into WinXp then shuts down.

I have to go through this several times and it is getting worse. Now, the computer shuts down randomly during operation at normal temperatures.

Does anybody have any thoughts about what else I could do except for swapping out the motherboard?

This reminds me of a brush I've had for over 20 years, it's had 4 new handles and 6 new heads...

...in other words with all the replacements you've made, you may as well have bought a new pc!

The key diagnostic step is during the POST. Any beeping happening or post codes appearing? Get the BIOS manufacturer's online guide and set your system to do the full POST and make you you are not bypassing things like the memory check and doing things like 'fast boot'.

Go here: http://www.bioscentral.com/ and find your BIOS/Board for the info.


My guess from your description is that you had a critical heat issue on your CPU at some point. A CPU/Board will exhibit the system behaviors you describe (unexpected shutdown at random times during operation) because once they fry they are more or less junk even if they seem to work for short stints. Grab a CPU/Mobo combo form somewhere and re-install. Since you already replaced power and disk you are practicably rebuilt and will have a good PC for a few more years.

While you are at it just replace your memory too as it can be impacted if there was an overheat and it is crazy cheap right now.

 

[TonyClifton]

A tiny crack somewhere in the MB pattern. Metal expands and connects when it gets warm.

Yup, you were right.

The mother board was the culprit.

I put in a new used one today and my computer works fine.

Thanks Liar.

If you ever need a used computer, please contact me.

CPUs can heat up very quickly

but not instantly.
My desktop is shutting off quickly also. My fan's working and I could run MB and MEM diags without it overheating and shutting off. Using Speedfan and the BIOS to monitor, I now see it must be that the chip that senses the temperture must be bad. It wound jump from 40c to 103c in an instant, which Windows detects and shuts it off.

Looking for an old motherboard now.

obtw, fans and heatsinks are both needed.
In testing, you can do without a fan a lot longer than a heatsink.
Without a heatsink, it will overheat in seconds or less.

Few possibilities to also consider when this happens
1. Bad power supply
2. Virus - to eliminate this possibility try starting in safe mode or boot from a jump drive (is suggest using puppy linux)
