computer starting problem

alluu · Feb 14, 2014

Hi!
First I want to apologize if there is some grammar fails because English is not my mother language :lol: OK so, earlier this week when i started my computer normally, it turned on then like in 2 secs it turned off, then after that when i pressed the power button again nothing happened, so i took the power cable off and waited couple of seconds and plugged it back in and then my computer started normally. After that day it has happened every day on the first start

That problem first came out, when i had bluescreen problems (which is solved now, it was bad ram issue) and back then i tried my friends corsair 4Gb 1600Mhz ram for memtest, and when I placed that corsair in and started my computer it turned off like in 2 secs. That was the first time it happened, I think that didnt anyway harm my computer because it was compatible with my MOBO. I have been thinking that it might be my PSU. My PSU is antec neo HE430W, and its like 2 years old.. :pfff:

I havent done the paper clip test yet, but i checked the voltages with speedfan and i didnt really understand is the voltages ok or not... so http://postimg.org/image/onpght2k5/ <-- its there.
I wish someone could help me solve this, I would really appreciate it

Oh and my specs
Motherboard: Asus M4A77TD
processor: Amd phenom || x4 965 Black edition
Graphics card: msi radeon 6850HD cyclone power edition
RAM: G.skill ripjaws 2x4Gb 1600Mhz

A 2 year old PSU means nothing; a quality PSU will still work when it's 10 years old. However they can also fail a lot quicker. You could try a different PSU, but it could also be the motherboard or another component.

Check voltages in the BIOS or use a DVM.

I checked voltages from BIOS and they seemed to be ok, the weird thing is that when I shut down the computer after using it (like its still ''warm'') then it starts normally without any problems, that problem will come only when starting the first time when i haven't use it in the day before

It could be capacitors ageing of MB or transistor. Also you can try with a single stick of RAM. I heard G.Skill RAM's has this problem on a cold boot.

GhislainG · Feb 14, 2014

I never experienced that issue with G.Skill memory (I use it in several systems), but I've run into it with an old Asus motherboard that I eventually had to scrap. I would try a different PSU for a few days.

hi and thanks for the answers, I did a cold boot just now and it did boot normally without any problems! earlier this day i did avg computer search and It found a threat (virus), so after then it now did boot normally without turning off after 2 seconds. Could that been the problem? well I see tomorrow after another cold boot

alluu · Feb 14, 2014

and plus for that, Last time i searched my computer from viruses was 28th of january, and the booting problem started in 4th february

GhislainG · Feb 14, 2014

A Windows virus can't cause power up issues; however it could cause booting issues.

alluu · Feb 15, 2014

Ok, but strange is after deleting the virus my computer has started 2 times now normally when cold booting. So the virus still did something? before deleting the virus every time i did cold boot, it turned off automatically 2 secs after pressing the power button

GhislainG · Feb 15, 2014

Hope the issue doesn't come back because the system certainly didn't start booting within 2 seconds.

lonewolf7 · Feb 15, 2014

So far so good. Cheers.

alluu · Feb 15, 2014

I think its done now, 3rd time cold booting and it was normal

anyway thanks for answering and helping, really appreciate it!

lonewolf7 · Feb 15, 2014

You are welcome.

alluu · Feb 19, 2014

Well ****! Same problem came out yesterday, and today i cant get it even started

taking out power cable and putting it back in doesnt even help anymore, it does it everytime. I guess i must take a risk and buy a new psu with all the money i have left now and hope for the best..

GhislainG · Feb 19, 2014

How did you determine it's the PSU and not the motherboard? Both can cause that issue.

lonewolf7 · Feb 19, 2014

Try to borrow a PSU from someone to test, before buying a new one.

You can test the MB too, remove all RAM sticks then start the PC, if you can hear beeping sound then probably the MB is ok, else its dead.

Or try a tech or service centre before you buying anything from assumption. Good luck.

alluu · Feb 19, 2014

I tried starting without any ram sticks installed, didnt hear any beep. Does that tell for 100% sure that my mobo is broken? I can borrow another psufrom my friend today so i can test with it

GhislainG · Feb 19, 2014

Is a case speaker or piezo installed? If not, you won't hear any beep. If it powers on, have you checked all PSU voltages with a DVM? Trying another PSU should at least help you determine if the PSU is good or not.

lonewolf7 · Feb 19, 2014

Yes the MB is dead, it will beep without any RAM or GPU. I have a Intel WX58BP MB (1366LGA) few years old with no speakers installed, still it beeps without RAM and GPU. The funny part the MB didn't come with any speakers from vendor.

To make sure and for peace of your mind you can test with different PSU, but I strongly feel the MB is dead.

alluu · Feb 19, 2014

Well i checked the voltages earlier from bios when my pc was able to start and they were ok, and yeah i dont have case speaker installed. I test it with another psu in about 2 hours, so isn't there any other way to test mobo that it is or isnt working?

lonewolf7 · Feb 19, 2014

Atleast I don't know any other way to test the MB. Try with the PSU then please reply back.

Hi! I tested with cooler master 700w and started like a dream, so it was the PSU?

alluu · Feb 19, 2014

After testing with that cooler master, i changed back to my antec neo he430w and now this started normally?

im really confused...

lonewolf7 · Feb 19, 2014

So far so good. Test it for couple of days then see what happens !

alluu · Feb 19, 2014

I needed to take it back because my friend needed it :/ but do you have an conclision why my own psu couldnt even start the pc but after using that coolermaster 700w my own psu started the pc normally?
