Solved DX2300 Won't stay powered up

November 28, 2018 at 06:47:02
Specs: Windows 7
I have a DX 2300 I use as a file server (Workgroup only) when I power it on it acts and sounds as though it will boot up but does not. When I hit the power button the lights light up on the devices and the power fan spins for about 2 seconds then everything dies. There are no beep codes. I have replaced the power supply but that did not help. I swapped memory chips. That did not help. Anyone have any ideas?

Try temporarily disconnecting the hard dive(s), removing any/all add-in cards, & disconnecting all external devices except the keyboard & monitor. Then see if you can boot up & access the BIOS. If you can, one of the disconnected devices is what's mucking things up.

long shot, try this:

unplugging the power cable
then holding the power button for 20seconds
followed by plugging it back in and powering it on

i5-6600K[delid]@4.8GHz/4.4GHz@1.424v LLC=6 | 2x4GB Crucial-DDR4-2133CL15@14-14-14-30 1T 2800MHz@1.37v
MSI Armor RX 570 4GB@1415Mhz core@1.2v/1920MHz

Try booting into BIOS set up. if it will run in set up then it is probably not hardware. If it does not run in BIOS or does not stay up then it probably is hardware related.

Clean the contacts on the RAM with a soft clean pencil eraser (even new ones), remove debris and pop them in and out of the sockets 4 or 5 times to burnish the contacts as well.

Try booting off a live Linux disk (puppy Linux, etc., do not attempt to install it though), like the first test it will let you know if you have a hardware problem but also if you can access ('mount') the hard drive and some of its files, it will let you know if the hard drive is bad or not.

You can boot off Seatools from Seagate and test your hard drive (short test) to verify it is good.

Report results for further suggestions.

Thank you!

It won't stay powered on long enough to get into the BIOS.

Thank you though!

Randomly replacing parts isn't a good troubleshooting method. Had you been having any problems or errors just prior to the no-boot issue? When's the last time you cleaned the interior of the case, especially the heatsinks & cooling fans? Overheating due to dust build-up on the heatsinks can cause immediate shutdowns. A bad or weak power supply might also cause a quick power on then off condition. Did you buy an HP/Compaq replacement or an aftermarket PSU? If it's an aftermarket, did you get a decent name brand unit?

No problems or errors before this. Case was cleaned less than two months ago and is still very clean. No dust collection anywhere. It is not an HP replacement PSU. It is an Antec 450 watt ATX PSU.

Thanks for the links but I can't even boot to a CD or the bios. Therefore, I cannot even run insight diagnostics from a CD.

I also looked for burned or bulging capacitors and found none.

Check the CPU heat sink, with the system unplugged and you grounding out any static charge you may have picked up, grasp the CPU heat sink and see if it can move at all.
If the heat sink can move or if you even accidentally unlocked the heat sink hold downs, the heat sink needs to be removed, the old thermal compound needs to be removed and new thermal compound needs to be added (properly, see directions, link) and the heat sink reattached.

No movement at all. Everything is tight.

I tried that earlier on. I disconnected each internal device one at a time trying to boot to USB device and to BIOS and it made no difference. I am really leaning towards this being a CPU or motherboard issue.

I am thinking it is time to scrap this one and get something else.
