Solved Computer turned off suddenly, now doesn't turn on

[linnemeyerhere]

Take your time and just have a good look around the various settings. Remember that hitting enter or esc keys plus the up and down arrows is the navigation tools. Only once you've had a good look around, set your date and time and maybe seen some interesting settings like boot options and temp. controls.....then you hit F10 and it will save those settings. If you don't like or want to explore more setting just go slow, write the changes down and at the next boot if you like or don't you can always make more or less changes. If it all gets too much then find the restore to factory/bios defaults and this wipes all the settings other than date and time back to how the bios original was configured.

thanx..and any ideas what psu i need.wattage i mean

 

[linnemeyerhere]

Getting back to the PSU. I always recommend that you get more power than you think you ever will need because it will protect you in the future as the PSU's cap age, it will run cooler and quieter and likely can then be used with many mobo and other component changes. Please consider a modular design or what I'm gearing towards more is a semi modular design. This will save you money so you get all the advantages of modular design and can take the savings or bump the wattage with the savings.

This may seem overkill and you can find many lesser powered examples. But this example will carry forward for many mobo's !

Great to hear you found the issue.

For BIOS:
You do not need to configure the BIOS for normal operation - but there are a few settings to be aware of and check for good performance and/or personal preference.

The first is the mode that the SATA controller is in: IDE or AHCI. This setting is normally found on the MAIN Tab under Storage Configuration (or similar).
If you are not aware of this setting (you've never changed it) and the computer boots OK, then forget about it.

The second one that you may have set yourself at some point would be to Enable or Disable certain on-the-motherboard devices (Sound, extra SATA Controllers, Firewire Controllers, etc). These are usually listed under the Advanced Tab.
Again, if you have never manually changed anything here then forget about it.

Last, is the BOOT ORDER (on the BOOT Tab). If you have a preference and/or need for the DVD to boot before the HDD, for instance, you set that here.

For the average user that is all that ever gets changed. Most computers run on the BIOS defaults.

Caution: messing with settings in BIOS that you don't know about "for fun" can really ruin your day! Don't play here. If you are curious, ask us!

EDIT: Wow! World's slowest typist!!

This is a nice little tool for calculating the proper size for a power supply:
eXtreme Power Supply Calculator

I always multiply the wattage it gives by 1.5 and get the size that comes as close to it (on the higher side).

@linnemeyerhere

1050? wow..my now broken ps is 585W

@TVeblen

actually my BIOS was configured in the store.so i dont know if they changed something before i reset it.but i guess it'll be ok..

 

[linnemeyerhere]

I thought that might get your attention. Funny is that's the wattage I use. I would say that 600-700 for you will be perfect but the way I look at things is how well do you know what your interests are 5-10 years down the road. You purchase a 850-1200 watt PSU and you will be styling for many years beyond your imagination. Now if you don't see your self building your systems in the future then go with the 600-750 range. By registering my 1050 unit it was warranted for life and that along with my love of the build had me think in these higher terms, as they say "your mileage may vary" !

 

[praeambulus]

thank you..yeah.actually u're right

 

[Zepher]

I would recommend a decent 650watt PSU. I prefer Antec, all of my systems have had Antec PSU's in them for the past 12+ years and only one developed an issue, it started to whine one day.
It was still in warranty and Antec replaced it with a newer model, which I am still currently using in my main machine.
My machine is on 24/7 and has more stuff in it than the average computer.

how do you get the Lifetime warranty? It says only 7 years, which is still a long time.
there is no mention of Registering and getting lifetime, unless it's stated on the warranty card in the box.

 

[linnemeyerhere]

Zepher,
The lifetime warranty was with my PSU which is an Ultra X4 1050. Sorry I didn't make that very clear. I saw that and jumped on it with all of their products. So far only a internal fan controller/card reader has failed and needed free replacement......I'm currently knocking on wood ! lol

Ok, the 7 year was on the PSU you linked above, which I thought was the one you had.
I see the one you have is 3 years then Lifetime when you register.

btw, the Ultra X4 1050 is $220 at TigerDirect, if the op is willing to spend that much on a PSU, might as well get the Ultra with Lifetime warranty.

guys, can anyone assume what the problem was with my ps? i have only been using it for 3 years

capacitor(s) failed maybe

 

[praeambulus]

so is worth to buy a 1050w if it can be brooken in 3 years or so..most of the times our retailers give 1 year warranty only

 

[linnemeyerhere]

I think you'll find the difference in prices from a quality 600-750 vs a 850-1050 to be in the 45-80 range for me it's a no brainer as the dynamic headroom of the higher wattage allows for markedly lower operating temps and stability in heat and high power draws while gaming. But there will be many that would and could dispute this. In the end it's my knowledge of audio amplifiers and headroom that has brought me to this conclusion. All this being said I'm sure what ever wattage between 650-1050 you opt for will give good service and work well.

 

[praeambulus]

yes.but what are the chances of a power supply unit to fail? because as i said above warranty is a problem here...and i really wonder what would cause my ps to fail

Heat and age will cause it to fail. They aren't designed to last forever.

 

[linnemeyerhere]

The quality brands all use Japanese caps and are built with heavy heat sinks and good ventilation. They will have a much greater life span !

 

[FaberTech]

guys! i finally tested with another PS.and im writing from my own computer..that was indeed the ps problem..thank you guys TVeblen and FaberTech..u helped me a lot.now i gotta buy a new ps..and actually reconfigure the bios(don't have clue about that xD).but that'll be easy i guess

again i really appreciate ur help!

I believe the instructions could help starting at page 35 with configuring the bios. its always a good idea to reset it anyway when installing new hardware. hey the coolest thing is you learned a lot about troubleshooting in the last few days. I'm glad it wasn't something major like the mobo. that would have included a reinstall of windows. Good for you man.
