PC partically boots

By Gmuscle ·
My PC has been running for over a year, recently I have experienced a problem when trying to boot up. It all started when my PC would just shutdown without warning. I thought maybe a power supply, so I changed it. the PC has ended up in the same if not worst case.

When I boot the PC it only goes thru IDE search and then shutsdown. Board is fine, memory has been tested and is fine, what could be the problem. Any suggestions?

Boot Device

by gsquared In reply to PC partically boots

When it POSTs (Power-On-Self-Test) and gets to the IDE detect, does it find drives?

If so, is the boot sequence of the drives set correctly in the BIOS?

I have no IDE harddrive only SATA drive. This has always been the case.

Drives detected

Okay. In that case, does it find the SATA drives while POSTing?

P/S, MB, and RAM are OK. Then it's got to be the CPU.
CPU could be faulty or overheat.
Test the CPU and fan. If they are fine, back to square one.

Thanks for all the suggestions. I have tried many of these to troubleshoot the problem. I will try the POST test mentioned and see if that give more information. And yes, I have good backup.

A computer that shuts down

It could be lots of things. Replacing the power supply was a good idea but did you replace it with a better one? It could be that your system is drawing more power then the power supply can handle.
This can affect the CPU, memory and other things because the power to them may fluctuate and damage them.
Other things that can make it turn off is over heating, is your computer clean inside and is there enough room around your computer so that it gets good air flow? Is your CPU fan working? And spinning at the proper speed?
Try removing every thing except the video, memory and the floppy if you use one. To see if completes the boot process. Another option is to buy or take to a shop that has a post card. This is a card that is placed in an empty slot and will tell you where the post stops, so you can tell where the problem is.
It may sound too simple but a CD rom or DVD player going bad can stop a computer.
Last do you have an anti virus program and spy ware/malware programs that you keep updated and used? You do keep back ups right?

After some trial and error, I found the problem. My CPU heat sheild had been slightly moved off the CPU. Once I coorect the problem, the PC came up and stayed up without a problem.
