According to the extreme power supply calculator (http://www.extreme.outervision.com/psucalculatorlite.jsp) you're perfectly safe.

For your system, it recommends a PSU with a wattage rated in the 250w area, so you've got plenty of headroom to work with.

 

[CokeMD]

Ok. I'm having some serious stability problems though. My machine keeps freezing, and i have to restart windows xp pro. Also a few days ago, my pc froze and when i restarted windows, i was told that /windows/system32/config/system was corrupt or unreadable, so i had to install windows.

 

[coret]

How old is the power supply?

When you next restart, go into the bios and check the hardware monitor. Specifically, check the CPU temperature, 3.3v, 5v and 12v readings and post here what they read as.

 

[Gravemind123]

That is most likely a ram error or just a software error. When my ram had issues, it had symptoms of random restarts/BSODs.

 

[runswindows95]

Did you reformat Windows and are you still having the same issues? If so, as grave said, check the RAM first.

 

[CokeMD]

I have checked the ram with memtest, no errors.

 

[runswindows95]

At this point, my guess would be the PSU.

 

[CokeMD]

Cpu temp. 17C
+3.3V OK
+12v OK

doesn't state the exact voltage.

 

[CokeMD]

And the power supply is about 2-3 years old.

You should have 18 (at least) to 20amps

 

[CokeMD]

Ok, I'll buy a Zalman ZM600-HP.

Will a power supply like this, use all 600watts even I'm only using a few devices?

 

[o1die]

I'd check the windows control panel for any driver conflicts. Then I would unplug any devices you don't use very often from the power supply and see if the problem goes away. No point in spending money on the power supply until you're sure it's the problem.

 

[coret]

No, it won't draw 600watts ... power supplies supply what the components running off them demand, nothing more. Having a higher wattage PSU than what your system needs means the PSU doesn't have to work as hard to supply the required power ... which means it's more efficient (power your computer needs and the power the supply draws from the wall will be a lot closer) and will also produce less heat, and deliver more stable voltages.

Hi, well I ended up buying the Zalman ZM600-HP.
I formatted my drive and have reinstalled windows xp pro sp2, installed all updates, now how do I test my system for stability?

Prime ?

 

[CokeMD]

Also SpeedFan says my core is62C...That was after i turned the computer and had no major cpu usage going.

temp1: 34c
temp2: 43c
temp3: 39c
hd0:33c
core: 14c
core: 62c
ambient: 0c


That can't be right can it? 62c is really hot.

I downloaded sisoft lite, gonna try the burn in test once i work out why the core field says 62c

 

[CokeMD]

I downloaded core temp 0.95.4 beta, and it reports my core #0 at 16c and core #1 at 18c

The first 'core' temp, on speedfan 4.33 matches core 0 on core temp 0.95.4

Hmmm, have i answered my own question?

 

[randomizer]

Do you live in antarctica or something, because those temps are below ambient for many places or very close to them? I'd say the readings are off.

 

[CokeMD]

Which temps are you talking about?

 

[randomizer]

16/18C from coretemp

 

[CokeMD]

I live in New Zealand. So no, its not the room temperature

 

[randomizer]

Well I live in australia and considering it's nearly summer there should be no reason why your temps are that low unless you watercool and undervolt. Unless you live in a cold part of NZ, I don't know how close our temperatures are, but we are at about the same latitude.

 

[CokeMD]

My room is currently cold, but not THAT cold.
The BIOS is reporting a temp of arond 35C for the CPU
