HP Recommended
Product: HP 8300 USDT
Operating System: Microsoft Windows 7 (64-bit)

I inherited two old 8300 USDT's. They were working until I updated the BIOS and changed from IDE to AHCI on one of them and on the other I did not update the BIOS but I changed from IDE to AHCI.

 

Both now have the same exact issue. Neither will boot. The screen is blank, (no signal) no beeps, no light codes. After about 30 seconds, the fans run at full speed. This has nothing to do with the OS. It doesn't get that far.

 

I have tried replacing the CMOS battery, pushing the CMOS reset button and removing the SSD and memory. I cannot get it to post nor can I access the BIOS. I do get the "bad or missing RAM" beep code with the RAM removed when I attempt to boot.

 

I think it would be too much of a coincidence for both motherboards to crap out at the same time. It seems to be a BIOS issue.

 

So is there any way to recover?
