GA-EX58-UD4P reboots on Windows load with Zalman PSU

Hi everyone,

I didnt know where else to go, so I decided to register here and see if anyone can help me out.

Here is a brief description of my problem.

I recently bought new components to build myself a nice small rig:

CPU: i7
Mobo: Gigabyte GA-EX58-UD4P
GPU: Gigabyte GV-R485MC-1GH
RAM: 3x2GB Patriot
PSU: Zalman ZM750-HP
HDD: WD 1Tb SATA
OS: 64bit WINDOWS 7 RTM

While installing OS, I kept getting stuck at not being able to complete the install - the PC would reboot on loading back into windows.

I tried everything - from reformating to trying to install XP. No go.

Took it to PC shop, and they diagnosed that PSU was causing the reboot, so I sent it off to ZALMAN, who said PSU is good and sent it back to me. I put it back in - same story - PC reboots while trying to load Windows. The problem is that I bought PSU from a different shop, which refused to refund me money or exchange, as they said it's in working order as per ZALMAN RMA results. So I'm now stuck with $1000 worth of hardware gathering dust in my study.((((

I updated BIOS to the latest Gigabyte version available on their website.

Anyone has any ideas on how to proceed?

Thank you in advance.

Check to make sure the ram specs are correct.

My buddy used patriot with his i7 and had issues.

Try different ram or a different PSU, it has to be either or.

Great job bilbat! Sounds like Zalman PSU and Giga EX58 is a bad combo.

I'd point out these 3 threads (likely are more) to Zalman and have them replace your PSU with one that will not only work, but work with the EX58.
