The Promax servers are Windows based machines so they are relatively similar to a PC workstation. Here are a few things to try out.
External Power - Check power source that it is able to actively power devices. Reseat power cables and modules if device is applicable.
External Devices - Ensure there are not external devices connected. This may include firewire and card readers as well on certain systems.
Power Capacitor Check - Unplugging the power cables while off and holding the power button for 30 seconds. Plug the power back in and power on.
CMOS Battery - Check and reseat the CMOS battery on the motherboard. You may need to purchase another battery from a local electronics store or online retailer. An indication that a battery has depleted, check the time in the bios.
Operating System Check - Try booting into Safe Mode by using the F8 key on the keyboard so that Windows is able to load. Once that is able to boot, restart so the server may boot into a normal state.
System Drives Check - Go into the bios screen. If you need instructions on how to get to bios, click here.
Depending on the manufacturer, you may need to navigate around the bios to find where the hard drives would be found.
If the drives are not seen, you will need to access the internal components. Reseat the cables on both the mother board and drive(s). To reseat the OS Drives, please see article here. If drives still do not show, you may need to replace the SATA cables. If the SATA cables are replaced and drives are still not able to be seen, the drive(s) may potentially be bad.
If the SSDs are bad, you may need to purchase new SSDs to prepare for a reimage. Once new SSDs are purchased and ready, click here for reimage steps.
RAID Check - When the system is completely powered off, remove the RAID drives but have them in the slot but at least 1" out so they do not make contact with the connector. Please ensure that these drives do not fall out of the server. If they are at risk of falling out, please remove the hard drives and place them in a safe and secure location and note the order.

Once ready with all drives not making contact, attempt to boot again.
If server still does not boot, the RAID controller will need to be reseated. Instructions for reseating the RAID controller can be found here.
If the server still does not boot into Windows, attempt to boot without the drives and RAID controller.
