Computer turned off durring first boot and now wont start up

by Gorthaur / July 22, 2004 6:06 AM PDT

I finished building my computer yesterday but had to go to work so waited untill today to turn it on and when I started it everything worked just fine and it started to boot. I got a message about how one of my IDE cables are too slow for a drive so it would be downgraded in speed. Then it said that a new CPU has been detected press F1 for setup. I pressed F1 and then it just hung there for about 7 seconds and then it just truned off.... I tried to turn it back on but nothing happened... I unplugged it and opened it up and disconnected some case fans thinking that maybe my 450W power supply wasnt good enough and then plugged it back in and turned it on. this time it stared up and was running tests again and gave the same message about the IDE cable and then it just turned off again. the small led light on the motherboard was still on but it wouldnt start up. I found that if I unplug it and then replug it back in I can get it to light up the fan lights for a split second but it wont even start up now... ummmm help?

P4 530 3.0 ghz 775 socket

2x 512MB DDR 400
radeon rx600 xt
WD special edition 120gb hard drive
Asus 16x dvd rom

4 red led case fans

Is there a heatsink and fan on the CPU?

I must ask this. Not everyone knows how to build a PC.

Yes there is. everything I bought came in a sealed retail box except for the hard drive.
The fan works. or it did work when it was working for like 30 seconds untill the whole thing turned off.

I built a computer about a year and a half ago and that one worked right the first time.... I am thinking there is something wrong with either the processor or the motherboard. I really hope not though.

Since it just turned off, you need less parts.
by R. Proffitt Forum moderator / July 22, 2004 8:24 AM PDT

The usual gaffe is an extra metal mounting post shorting out the back of the motherboard. Check your work.

Next I strip it down to just Power Supply and motherboard and NO CPU, nothing else. It will power up or you are looking at the two possible bad parts.

I hope you didn't take my first question too badly. One must ask such things.

Tried it with just the motherboard and power suply and still no luck.
I then decided to take the power supply out of my old computer and tried that with just the motherboard and to my suprise IT WORKED!!! I then plugged everything back in and started it up again and I got as far as I could go untill I manage to find where I hid my windows xp CD. Thanks alot for the help. I just need to get that power supply replaced and then I should be good to go. =D

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
