After turning off Pc, it takes many tries for it to finally boot up. Why?

Question

Hello,
I have a nice pc, custom built from parts i bought from NewEgg.com. It's about 4 yrs. old now, but it still has everything top of the line, even now it's about as good as a new pc you might buy.

But when i turn it off, (which i rarely ever do) it takes many tries turning the power button on & off , over and over until i hear a beep, then i know it will boot up.
I don't know why this is happening, it's been like this for over a year.

My memory is crucial ballistix tracer ddr2 8500/1066
My Power supply unit is a SeaSonic M12 SS-700HM ATX12V/EPS12V, 80Plus, Active PFC.
And my motherboard is Asus P5K Deluxe with Wi-Fi.

I heard this might be happening because the Psu might not be giving 12v within + - 5%, or it's my memory.
Can somebody tell me just what kind of Gremlin might be causing this, i've never seen this problem anyone's pc .

Thanks for taking the time to read this long post, and especially if you can help in anyway, thanks in advance!

Answer 1

>Most likely, you have a nearly dead motherboard battery. Replace the motherboard battery.

Answer 2

The power supply is failing. That's surprising, seeing as it's a Seasonic. But then again, even the best quality power supplies are usually only good for 5-6 years, maximum.

Electronics components run most efficiently in a certain temperature range. If your power supply is too hot OR TOO COLD, it is not able to supply as much DC power as it usually would.

You leave the computer on all the time, the power supply is operating efficiently. No problem.

You turn the computer off and now the power supply gets "cold" and can't boot your system until it's been warmed up a bit by attempting to start over and over and over again.



This could also be a problem with the motherboard, but I don't think so. 99.99% of the time when you have this symptom, it's a bad power supply. I would suggest you get an EXACT replacement, if they are still available. That is, don't change the model of the PSU, just get a new one.

Answer 3

If your PSU is not giving you full power on any of the rails, your computer would be randomly crashing while the PSU was under load.



If you are overclocked at all that could be why. On most ASUS and Gigabyte boards I've seen (all that I use) if the board doesn't like the overclock, the computer will continually start over and over, and post only after a few of these on-off cycles, or after I hit the reset button. The rest of the time they work fine.



It's possible that your memory is dying, I would go through a pass of memtest.



Other than that, I would be putting blame on your motherboard, I couldn't tell you what specifically on your motherboard is the issue, but finding either a new or used 775 board for cheap shouldn't be that hard nowadays.



Hope I helped.



EDIT: if it was your CMOS battery you would be getting "CMOS Battery Failure", "CMOS Checksum Failure", "CMOS Read Error" or "OVERCLOCK FAILED" errors after you've successfully posted. I doubt that is the cause.

What anybody suggested is amazingly authentic: ust could desire to be the foremost clarification for the activate situation, yet be careful, use a hoover, and a Cotton bud to bathe small slots and holes. Too many huge classes may well be on your computer SO attempt to uninstall some which you do no longer choose too a lot. additionally run a disc sparkling, a Defragmenter, and verify blunders verify. decide for the 1st selection. Restart your computer, and watch for a a million/2 hour. Then it is going to log you often. and your start up may well be busy with too many classes additionally. So eliminate a number of them. Now, you antivirus may well be slowing down your computer, Comodo, does that. If it extremely is the undertaking, exchange it. Avira would not yet you will choose Antimalware alongside too. try Avast, it relatively is not too undesirable and fairly comprehensive. For the sunshine, it may desire to be a technical situation. I recommended you to verify it with a professional. it may desire to be the bulb, yet i'm no longer a computer engineer, so i will abstain commenting on it.

Answer 5

My answer is your computer daily work well. but still starting problem. so no mother board and etc hardware problems.i just ask a question if you on the computer without ram check the beep sound 3 times. else the problem was occured on hardware side. if here . go to bios setup. restore it. and then one more time start with RAM. now the problem will be occured. please rebuild your PC. beacause some times dustes are a main problem. so clean and rebuild. it will work correctly



thank you

Answer 6

You are not going to like my answer. The last time this happened to me my motherboard died and it took many troubleshooting hours to discover that my motherboard was bad and the fact that I did not want to believe my motherboard was bad added to those hours. Sounds to me like one of the capacitors went bad. A bad cap will force you to restart your computer over and over till it starts. After a while your computer will not even start any more.



The only other thing I can think off is the power supply.

Answer 7

I had the similar problem and it was due to the earthing which wasn't functioning well and then the PC developed current. I changed my PC's location to a place where the earthing was in place for the socket and I had it solved.

Answer 8

It is probabably one of two things:



1. Bad RAM

2. Bad Hard Drive



Be sure you are properly shutting your computer down rathar than holding down the power button.



If for some reason it isnt either of those it could MAYBE possibly be a bad CPU or Motherboard



We get many custombuilt machines in our computer shop, they have wonderful hardware but somehow those parts manage to malfunction.
