PC starts for 3 seconds!!!

by cubsandasfan82 / January 24, 2006 1:08 AM PST

My PC I built is having some early issues. First I had a stick of memory go bad on me. Then my 450W power supply overheated and was literally smoking. I got new memory and a 500W power supply and my PC will only start for a few seconds before shutting itself off. I'm not sure if my 500W power supply is the problem, the new memory, or another issue like my processor is overheating or bad motherboard. Any ideas would help! Thanks!

With Power Supply AND RAM Issues...

I'm guessing that the motherboard is the carrier of the disease..It may be the originator of the problems. Try replacing it.

Hope this helps.

PC start up problem?
by dbssmith / January 24, 2006 12:08 PM PST

Do you mean it will only stay on for 3 seconds? Or it will boot up then turn off after. No error messages? no chance to enter the BIOS? This might sound elementary because often the simplest things can trip us up but make sure you have the voltage switch on the powersupply to 115 or 110 or you know, North American wall voltage. I don't know, if it makes it through POST and then dies then it might be a harddrive issue. make sure it is jumped correctly.
To cavaliarly suggest you replace your mother board is not a friendly thing to do. But you might take it out if all else fails and see if you have a loose screw or something shorting the motherboard to the case. Take from me it happens and happens more often than you might think especially with novices nervous about building their first computer.
GOOD LUCK.

Thanks for the ideas guys, it ended up being the stock fan from intel. I have a Pentium D 820 and the stock fan upon further review was not working properly so I picked up another cooler and it is working perfectly. Thanks for the advice though!

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?
