I've got an MSI Z390-A Pro motherboard that starts up fine, but it's missing the VCORE (and VGT) voltages. All of the other voltages are present (e.g. VCCSA, VCCIO) and I know the CPU (i7-9700k) is good. Now, the original PWM controller (UP9521P) had an internal short and I replaced it with a new one. All of the enable signals look good. The problem seems to be the PWM signals going to the MOSFET drivers. I checked them with an oscilloscope and they are all flat 1.5V with no pulses. I don't know why this would be and I'm not sure where to look next. -
As this is a brand new forum, I thought I'd open up a thread to encourage new members to introduce themselves a bit.. now hey.. let's not get too personal.. ok ?
And if you wouldn't mind to keep this thread \"clean\" let's try to keep the the chitchat (i.e. even the welcome to the board replies) to a minimum or this thread may get to 100 pages fast
So I'll start things off :
My name is petabyte and I'm a forum junkie. :oops:
I've been off the wagon for a number of years and countless times I've tried to stop but it's useless.....

Hi,
I'm currently experiencing issues with my Dell Inspiron 5415. Initially, the laptop would sometimes fail to boot, with the keyboard backlight turning on but no display on the screen. After repeated attempts to power it on and off, it would eventually boot up and function normally.
To troubleshoot, I removed both the main battery and the BIOS battery, but now the laptop exhibits a different issue: the fan runs at full speed, but the screen remains blank, and it doesn't boot up.
I suspect there might be a problem with the BIOS, and I would like assistance... -
someone could share a BIOS file for the said model?. no display problem on this one.
board info:
330s_KBL_MB_V06
REV: MP
i attached my backup... thanks... -
i have an hp 17-121wm that restarts any time i want a load windows or any operating system. all signs and troubleshooting leads to the bios. would appreciate if anyone could help with the bios dump. my backup is below...
