What's wrong with my computer?

Starting about 4 or 5 days ago, my computer started overheating all the time. I have a program called SpeedFan than tells me a few different temperatures in the computer. Temp1 stayed pretty much the same at about 30C. When the computer was idling, Temp2 and Temp3 were usually about 40C. However, whenever I started to browse certain websites (such as youtube, facebook, or photobucket) or play simple old games (such as diablo ii), Temp2 and Temp3 would go up to 55C or 56C, and the computer would shut itself off.

I figured maybe the fans and heatsink were clogged with dust, so I took them out and cleaned them off, and put new thermal paste (silicone) between the processor/heatsink. However, now when I turn on my computer, it will not boot up. Both the case fan and heatsink fan run at full speed, but the computer will just sit there. I'm pretty sure I hooked everything back up correctly (I only had to unplug one fan).

What do you think is wrong with my computer? Did the processor get fried? Are the temperature sensors whack? Did I accidentilly drip thermal paste on the motherboard and cause a short?

This has cured several problems with this computer in the past, but no luck this time.

Check the CPU heatsink.

It may not be fastened down properly.

I'm pretty sure it's on there correctly.

Make sure to try some uncoventional combinations of profanity. Do not underestimate the power of a really creative mumblecurse.

It could be that your CPU finally bit the dust.

I'd recommend replacing it with a Pentium II or better.

haha...I have an old Dell with Windows 95, 96 Mb of Ram, 4 Gig harddrive, and a 233 MHz Pentium II processor that I've been using while my main computer is down. Unfortunately, I have no way to connect to the internet with the old computer, so all I can do is play really old games on it.

The problem is most likely due to laminar air flow over the effected components. Placing a turbulator on the discharge of the fan should resolve the issue. If not, take two aspirin and call me in the morning.

The processor that's in it right now is a Pentium 4 LGA775 2.93 GHz, 533 MHz FSB (I think), 1 MB cache (I think), and non-HyperThreading.

If I wanted to replace it, would this guy work?

Shooting in the dark, did you at any point remove your RAM sticks? Just for sanity, re-seat them as well as the processor. If it's still blank, try removing all expansion cards and re-insert them one at a time, starting with the processor and RAM, until you find the problem (if you find it at all).

Did you ground yourself while doing that work? Very rarely, static charge can fry hardware components when working ungrounded, so that might be a possibility.

You have Socket 775, so it really depends on your motherboard. That processor is pretty good, but you might have other options (Pentium D, Core Solo, Core Duo, Core II Duo, etc.)

Untrue.

Didn't remove RAM, but I did reseat it just to be sure, but did not fix the problem. I did take out the processor to clean it off, but I'm pretty sure I got it re-seated pretty well again. And no, I was not grounded.

Lets see....

There's a chance you might have bumped one of the cards or memory chips. Try reseating all of them. As for your CPU shutting down, the BIOS settings might have been set to shut down the computer when the CPU hits a certain temperature. You could probably bump it up 60-65 degrees C. Heck most CPUs can run at 100 degrees C no problem (the GPUs on my video cards do), the low shutdown temperature is just there to protect you in case the heat sink pops off somehow or you didn't attach it.

And silicone paste? You need to switch to Arctic Silver (i prefer their Ceramique paste).

The OEM BIOS from Acer doesn't let me change many settings. I've had issues with it before trying to upgrade RAM (see thread). And I can't even access the BIOS right now since the comp just sits there spinning its fans upon powering up.

Try replacing the fan; it might be faulty. Either that, or try replacing the heatsink.

The only two reasons why the fan would be going at full throttle that often are because of inadequate cooling to the CPU or (if applicable) the GPU, or (less likely) because of a bad fan.

While Jsharr's initial diagnosis was a step in the right direction,,, it sounds like you are ready for the USMC approved diagnostic regime. It is called the Drop Check. You start with a 1' drop check, if that fails proceed to the 2' drop check, followed incrementally until you can no longer lift the asset any higher or you have permanently "fixed" the problem to such an extent that supply will issue you a new asset.
