Okay so the GPU on my laptop (nvidia card), has gone bad and I have confirmed this with Nvidia (cause Dell would have been a headache). Anyway I needed to turn it on to get some stuff off of it, and decided to put this temperature program to see what the temps are on my laptop. Well they were insane and it felt hotter then I rmemeber (I haevn'e used it since the part went bad). So could my bad (or should I say shot) GPU cause like a resistance of some sort and increases the heat of my laptop or do I have a cooling issue (and might be the reason why the GPU went). To give you an idea, i just ran windows media player (now the image was crap and laggy cause remember the GPU is shot) and the program I used (CPUID) the CPU hit 89C, DIMM 75C, and AUX 93C (which I believe is a case temp or motherboard). Thanks in advance

reported a dead Nvidia GPU plus very high CPU/DIMM/AUX readings. and are right to focus on cooling, but the key next step is to isolate whether the heat is a symptom (cooling failure) or a cause/result of the GPU fault. The checklist below favors safe, verifiable checks that do not rely on guessing.

  1. Back up anything important now and avoid heavy use until the machine is evaluated.
  2. Run Dell's built-in hardware diagnostics (F12/Diagnostics at boot) and note any error codes; those help decide repair/warranty options.
  3. Compare sensor readings outside Windows: check temps in the BIOS/diagnostics screen or boot a Linux live USB. If readings drop with no GPU driver/OS loaded, the discrete GPU or its driver/load may be contributing.
  4. Try disabling the discrete GPU (Device Manager or BIOS if available) or boot into Safe Mode and observe temperatures. A big drop points to the GPU drawing extra power; little change points to cooling/motherboard issues.
  5. Cross-check sensors with a second tool (HWiNFO/HWMonitor/OS-level sensors). Note that "DIMM" is the memory sensor and "AUX" often refers to a motherboard/internal sensor — inconsistent labels and bad sensors do happen.

If temps stay high even with the GPU idle/disabled, the problem is likely cooling path, fan control, or board-level damage and not just the GPU. If temps fall when the GPU is taken out of the picture, the GPU was adding heat or load. Do not attempt BGA reflow at home; if the GPU/motherboard is confirmed bad, get professional repair or a board replacement estimate before spending time on risky fixes.

Hi,

from your talks I am thinking that you're having a cooling problem, which isn't caused by GPU. I think that's the reason why your GPU went bad.. So, repair your cooling system by cleaning it and then retest system temperatures. I really think, that it will help you out. Write me back if this works!

It's a dell laptop so I am kind of limited

Why you're limited?? you can repair your laptop similar to desktop, yes it's more complicated, but you still should try doing something..

hi,start by,buying a can of compressed air to blow out the heatsinc and fan of the laptop
