Well as some of you may remember, I'm the guy that had the motherboard problems. Well after going out and buying a new case with the right powersupply I was ready to go *clicks heels*

So I put my old disk drives and my old hard drive into the new case, slapped in the motherboard and turned it on. And it turned off after a few seconds. Barely got to the desktop, which, by the way, looked really fucked up and no icons loaded.

Anways, I figure it's overheating and I go and buy a system fan (guess the one I bought didn't have one). Install that and it lasts longer now, but when it starts detecting the stuff (PCI cards and what not) it cuts to a blue screen which says something about a fatal error. Now at first, it would shut off immediatly after the blue screen, but now I can hit a button and it cuts back to the blank, fucked up desktop.

I checked the BIOS and it seems my CPU temperature is 175-190 degrees. I don't reckon that's all that good but hey, I don't know much about computers. Anyone have any ideas on this? I'm not in too much of a hurry since I kinda wanna take a break from this whole upgrading thing (I have my old mobo back in, haha). But it would be nice to know what might be the problem.

Well, if all else fails theres the PC repair shop, I'm sure they can do a better job than myself.

If that's an AMD and is not 64bit, that's high.
I just looked ar three systems to be sure before i responded and they're all at 110-120F for AMD 2000-2400 cpu's.
Somethings not right if so.
If it's Intel cpu's, then i cannot be of help but to recomend a better cpu fan and case fans.
When a machine shuts itself off, it's as a saftey against a to high temp. It will also shut off if a short is detected on the motherboard.

that's interesting. I'd put some thermal grease in between the CPU and heatsink & fan, that might fix it. That temperature is WAY too high for your processor. It shouldn't exceed 120 Fahrenheit give or take, I'd say. That is just completely too high of a temperature, it's most likely what's causing your CPU to overheat. I'd also check around and make sure your CPU isn't overclocked, but I doubt it is if you didn't do it.

I was thinking that might be the problem because I kinda smeared some of the thermal stuff they put on the heatsink but I was hoping that wasn't the case. Oh well, it's cheap anyways. I'll let you guys know how it goes once I pick some up.

Thanks.

Applying Heatsink Grease

Applying heatsink grease is a common question on many computer related forums. I recall it on overclockers.com as well as on my current favorite forum, Ars Technica. It's really a simple thing. I'll post a few pictures of a Chemtronics Silver Thermal Grease being applied to an FC-PGA chip here and will plan to update this later with PPGA and t-bird applications.

27 January 2001: Chemtronics silver on Intel FC-PGA and standard silicone thermal grease on i815E (BGA?).

You want a thin layer of grease on anything that you apply. It has to be thin enough that it doesn't inhibit thermal contact between the heatsink and CPU, yet it has to be thick enough to ensure that the heatsink and CPU are in good, even contact. Too thin and you don't get enough contact between the heatsink and CPU, and your chip cooks. Too much, and the heat transfer between the heatsink and CPU is inhibited.

Chemtronics Silver Grease application

1. Clean both surfaces-- the bottom of the heatsink and the raised die of the CPU. I use rubbing alcohol, but acetone can also be used. Make sure both surfaces are dust-free after you wipe them down with a damp (w/alcohol) tissue, I use a can of compressed air. Let both surfaces dry.
2. Squeeze a tiny drop of grease from the syringe. 1~2mm in size should do it, 2mm may be much too big. On FC-PGA (Socket 370) and Socket A chips, the clamping pressure is very high-- squeeze the heatsink on to the chip and most of the excess grease should be forced out.
3. Pull the heatsink vertically (with a slight twist or angle if needed) off of the chip. Examine the pattern and thickness of the grease left on both the heatsink and CPU. You should see little raised peaks or ridges evenly spread all over the chip and heatsink where there is good contact between the two.
4. Reinstall the heatsink and remove it again to check. If both CPU die and heatsink are reasonably flat, you should be able to see through the thermal grease and see the color below the little peaks of grease. Note the ridges of grease on the CPU die in some of these pictures-- those are areas of excess grease. Any areas of poor contact should be filled in with a tiny dab of grease.
5. Examine the heatsink. You doubtless see areas of excess grease around the edges of the area w/grease. That is NORMAL. You can try to wipe some of it off, but do NOT touch the center area with grease. You want signs of even, continuous contact on both the CPU die and heatsink.
6. If everything is satisfactory, install the heatsink!
7. Plug in the CPU fan and see how things go!

The keys are being able to see the color of the surface through the thermal grease and an even distribution of the tiny peaks all over the CPU and heatsink contact areas. These are pictures from what is only my second FC-PGA chip install and my technique is not yet very good. The small surface area does make things difficult compared to PPGA chips. Note the ridge of thermal grease off to one side of the center... that is not a good thing. I'll be switching from an Alpha PAL6035 w/Sunon 60mm fan to an Alpha PEP66 w/Delta thin 60mm fan soon and will try to post pictures of that install if I remember to do so.

Installing thermal grease on the i815E chip of my Asus CUSL2-C was much easier. It was regular silicone thermal grease as you can see from the pictures, and getting a thin layer was not as critical because the i815E produces much less heat. Still, note the even contact all over the surface and the tiny peaks I keep talking about. Intel chips seem to be more concave than they should be, so a little more thermal grease is needed for this application.

Get artic silver 5, its five dollars a tube.

Arctic Silver is good stuff, but it voids the warranty of the chip. AMD retail processors have between a 1 and 3 year warranty on them, and that warranty is completely fucked once you put AC3 or 5 on it. Of course, if you could find a way to get every last bit of it off without a trace, the warranty would still be fine.

If that doesn't work, simplify your system. Get back to the most basic system: motherboard, cpu, memory, video card, power supply, mouse, keyboard and monitor. If you get problems here, you can easily rule out the other stuff that was on your system.

If you still get problems, check here: right click on My Computer, select properties. Click Hardware button, then Device Manager. Any major hardware problems will show up as yellow icons or red Xs.

oberon

jujueye, that's a good plan. However, it has a caveat. Sometimes the problem is a conflict between two pieces of hardware, not due to any one piece.

soaking the chip in isoprophyl for a few days ?
