Hi,
I just installed my new PSU (Fatal1ty 750W) and when I start up my PC my screen doesn't work and I get a beep code in order 4-3-1-2. Couldn't find it on the internet so maybe you guys have an idea? My motherboard is a Tyan S5396 Tempest i5400XT

Your motherboard's power requirements are:

Power
• EPS12V/SSI (24+8+2X2 pin) power
connectors
• Note: If Slot6 (PCI-E X16 slot, the one
closest to the memory slots) is used,
4X1 pin power connector must be
plugged in)

Do you have all 3 of these connectors in place on the motherboard:
1 x Main connector (20+4Pin)
1 x 8-Pin EPS 12V
1 x 4+4-Pin ATX/EPS 12V

Recheck all of your components and connectors to ensure all are properly seated or connected. Most likely, something got jostled/bumped/dislodged while you were connecting the new cables/connectors. This should include the video card and memory in particular.

Double-check, specifically, that both the main 24-pin and the auxillary 4 or 8-pin power connections are firmly attached to the motherboard.

Everything is connected properly. Just checked it twice. Any other ideas?

Well, the manual doesn't say much about beep codes:


Chapter 4: Diagnostics
NOTE: If you experience problems with setting up your system, always check the following
things in the following order:
Memory, Video, CPU
By checking these items, you will most likely find out what the problem might have been when
setting up your system. For more information on troubleshooting, check the TYAN website at:
http://www.tyan.com.

4.1 Beep Codes
Fatal errors, which halt the boot process, are communicated through two kinds of audible
beeps.
• A single long beep followed by two short beeps: It indicates that a
video error has occurred and the BIOS can't initialize the video screen
to display and additional info.
• A single long beep repeatedly: This indicates that a DRAM error has
occurred.
The most common type of error is a memory error.
Before contacting your vendor or TYAN Technical Support, be sure that you note as much as
you can about the beep code length and order that you experience. Also, be ready with
information regarding add-in cards, drives and O/S to speed the support process and come to
a quicker solution.

If you still have your old PSU and install it, does the problem go away?
