Hello Techs, I have tried changing RAM, hard disk, power supply, but WHEA UNCORRECTABLE ERROR still persists. What I have not done is BIOS update, but I reset BIOS to Default settings.

This error is a kind of BSOD-error, the "blue screen of death". Is there hardware diagnosis available, with pressing "F2"? Any reaction from the BIOS? -
@FriedFred; the laptop enters BIOS on pressing F2, and memory and HDD tests passed. I noticed that each time the laptop is powered on from its power button, it runs for few seconds and restarts on its own. The laptop is an AMD processor.Comment

Probably it gets too hot, maybe the thermal paste is dryed out.
Do all coils show some voltage?Comment
-
@FriedFred; I applied some new thermal paste on the processor and the VGA, but the error persists. Yes, all the coils have some voltage.Comment

@FriedFred; a point to note is that when I stay in BIOS, the system doesn't restart, but as soon as it tries loading windows, it gives the WHEA UNCORRECTABLE ERROR. This is so worrisome to me.Comment

Hello everyone,
I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
🧩 Initial Issue- Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
- External display (HDMI) shows

Hello everyone,
I recently bought a non-working Asus Zenbook Pro Duo OLED UX8402ZA that was listed for parts only. The seller mentioned that it had no display output but that the charging lights worked.
When the laptop arrived (without a charger and SSD), I connected a charger and confirmed with a multimeter that it was charging the battery. However, when I tried to power it on, only the backlight of the secondary display came on. There was no image, and it didn’t boot into the BIOS.
I decided to try flashing a new BIOS, but since I didn’t want to desolder... -

Hello,
I updated my pc, from Evga z270 itx to Asus b660-i itx motherboard. In my old z270 motherboard everything whas easy because everything in bios was unlocked (fd, me etc), and could do everything I want.
Now in my Asus b660 everything is locked (except main bios region). I dont mind so much but I want to unlock bios so I can flash a new splash screen (I have done it with my old motherboard).
I made a bios dump with FPT (fptw64 -d mod.rom -bios), I modded it and I tried to flash back
(fptw64 -f mod.rom -bios). I got Error 167: Protected Range Registers are currently... -
Hi, my laptop wont boot at all
With original bios no POST, only LED lights
With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
Some issues
A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
B- If updated from 500LN version 203 to 300, the battery stops being recognized
Things I tried
1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble...
