GX150 keeps rebooting while already booting up
A friend has asked me to take a look at a problem he has on his GX150. During bootup, it reboots, not always at the same point, but sometimes during POST, sometimes as the operating system is starting up.
I think it may be a problem with the psu. To test my theory, I would like to replace the psu. Can I temporarily wire in a non-Dell psu, such as an ATX, or would that be a mistake?
If anyone has any suggestions, I would be grateful to be told.
My thanks in advance

A non dell power supply would connect to the motherboard but will not fit in the case.
The power connections arent proprietary the case is.

Thanks for your help.
I wasn't planning to fit the ATX psu in the box, just disconnect the Dell psu from the motherboard etc, leave the ATX outside the box with the box open, and feed the ATX output leads into the box to the motherboard/hard drive, etc. This was only going to be temporary to test if the pc problem was caused by the Dell psu. Either the Dell psu would prove to be okay, or I would have to get a repacement Dell psu.
I had heard a rumour that while DeIl used the same 20-pin connector type as an ATX psu, the arrangement of which pins had which voltages was different was, so that the ATX would put voltages in the wrong places for the motherboard.
Also I thought that possibly others had had this reboot problem, and new the solution

I have tried two ATX psus but the pc still keeps continuously cycling through Reboot. Therefore, I need to look for a fault elsewhere.
There are a couple of 2200uF electrolytic capacitors that look like they may be the very early stage of bulging at the end, There isn't any sign of leaks, but the ends do feel a bit domed (domed not doomed - not yet).
Thanks for your help

Problem solved. I changed all 5-off 2200uF electrolytic capacitors on the motherboard, and now the pc boots up normally.
Thanks for your help
