Alrighty then, my CPU is probably fried now, after everything that's happened and me not knowing better. Last night I basically backed up all my important data, took all day but it was done. So first thing this morning, before booting my computer for the day I thought I'd try and push my CPU a little farther with an overclock. It's a Core 2 Duo E8600 @ 3.33ghz, it was set to 3.6ghz with 1.5v, and I upped it slightly to 3.75ghz with 1.625v Something went terribly wrong there, probably the voltage tweak, because after that the display wouldn't come on. Windows was definitely booting as normal, but no signal. I had to open up my PC guts to reset the CMOS, which also involved taking out the GPU for a moment to access the jumper pins. Whilst I was in there I probably made a huge mistake by removing the CPU cooler fan to inspect the thermal paste. It looked a bit thin, but I had no way to remove the old paste in order to apply new paste, so I just put the cooling fan back on. When I booted the system after that, the signal returned and I was able to get into the BIOS again. Windows 7 tried to boot the first time, and failed spectacularly. It froze on the booting screen with only a red spec of the windows logo having animated. When I got into the BIOS, it became pretty clear I just messed up big time. The CPU was reading 2.00ghz, and wouldn't adjust along with the FSB. Then I examined the H/W health and was shocked to see the CPU temp had reached 105c. I immediately powered off the system when I saw that, and now I'm afraid to even go in there again for threat of causing further damage. So long story short, one thing lead to another, now my CPU may be burnt out. I have no idea if the system is salvageable at this point, I may need to take it to some nearby computer specialists and have them sort things out. Worst comes to worst, I'll need to buy a new computer. I had been wanting to buy a new computer in the near future anyway, but not by losing my current system. It may be nearly four years old, but I was hoping to give it to my brother who's using a 7-8 year old system. For the time being I'm stuck on my laptop. Anyhow, do you guys have any idea about the state of my system? From what I've described, is there any hope for the CPU? Could it be the 2ghz reading was only because of the critical heating? The system didn't shut off or make any usual noises, so I don't know.
