Alienware X51 R2: I feel like my HDD is overheating.

Fri, 09 Aug 2019 06:11:30 -0700

I feel like my computer's hard drive is overheating. Sometimes, when I try to put on my computer, the boot screen shows up, but it doesn't boot to windows. Note: my pc doesn't say that I have no bootable drive! When I get my pc on, it's constantly hot and when I open up task manager it shows my drive is having 100% utilisation.

Please help.

Alienware X51 R2: Weird PSU light shuts down and PC doesn't boot

Sat, 14 Mar 2026 12:18:53 -0700

So a few days ago I woke up to my computer being in a hibernating state to which I tried to wake it up with the mouse but it didn't work. The lights of peripherals were on and the Power light of the PC so I tried to turn it back on with the power button to which it shut off.

It started turning on and 2 seconds later turns off and the PSU cord which has a blue ring light shuts down while the PC is off when it turns back on is when the computer turns on too.

I removed GPU it isn't it, I removed the HDD and it handled a few seconds more on but it kept on shutting down, then I removed both RAM sticks and reseat them but they were not properly seated so the computer Mobo started beeping twice for (No RAM Detected) but it stopped shutting down, then I tried separately in different slots and no Luck. Tried replacing with the original RAM sticks and it did the same thing as the newer ones.

I even tried different configurations like for example:

no RAM no GPU and no CD Drive with HDD only and with the HDD it beeps twice for no RAM detected but it shuts down quickly right after the beeps the first time and then it shuts down right on the second beep. So the HDD and/or the RAM being seated are doing the same things.

My mobo is model: 0PGRP5

Alienware X51 R2: Getting stuck in a reset loop. reset, boot, reset, boot, reset,boot

Fri, 14 Apr 2017 12:40:18 -0700

I am getting random BSOD showing up on my X51 R2. It all started after a windows 10 update (I already had 10). The computer sometimes games for an hour and other times only 2 minutes before showing a BSOD and getting stuck in a boot/ reset cycle. It resets, boots for 1-2 seconds with the fan on full speed, then resets. This cycle carries on indefinately until I turn off the mains power.

I found a windows STOP CODE on a BSOD... 'BAD_POOL_HEADER'

I have seen 6 different windows stop codes

Looking into the 'fault memory' of the computer it is not logging these crashes as faults as there is no sign of a crash or reason

Please help#!
