overheating trouble and sluggish pc

By Norehca ·
For help with solving this problem ill list my pc's specs:

AMD64 3700+ (cpu fan/heat sync which is apparently made for 64-bit cpu's unknown manufacturer)
1GB DDR RAM (PC3200)
Geforce 4 TI 4200 8x AGP (prob doesnt matter)
2 large system fans + 2 fans on PSU (intake/output)
and a case which apparently is made for 64-bit based systems and is designed for efficient airflow

now the first problem is my pc is constantly overheating. ive tested with and without the cover of my tower, it overheats either way. its reached passed temps of 150 degress F. im afraid my cpu might be damaged which is linked with my other problem of my computer being vry sluggish. but first up, what could be causing my computer to be overheating? my father has a computer with an AMD64 4000+ CPU with 1GB of ram with only 1 system fan, yet his cpu maintains a temp of 100 degress. and he does NOT have amd cool & quiet active.

now the deal with my computer being sluggish, ive ruled out any viruses as ive just reinstalled windows and its doing the same thing. audio is glitchy, and everything becomes so slow to the point i can barely work with it. this happens when i do simple things like copying files, installations, etc. which i know should NOT slow down my computer to this point as it did not do this about a month ago. is my HDD or CPU damaged do you think? can you please help me, id rather not have to spend 500$+ on a new CPU or HDD. and why is my computer overheating? (my room stays at a decent temp of around 75-80 degrees btw |top floor..heat rises...uhg..parents screaming music is too loud constantly..ok another story|)PLEASE HELP!

its worst when copying files from a cd/dvd, or buring something to a cd/dvd. and another quick thing, is it safe to overclock a video card if you know its threshhold. for example, i know my VGA's cpu speed will start showing glitches past 300MHZ, so as long as i keep it at 300MHZ does that mean it will be fine?

Overheating and over clocking go hand in hand. The heating problem may have to do with blocked air flow. Besure fans are running in the proper direction, close inspection will reveal two direction arrows and they indicate direction of rotation and airflow direction. Sometimes you have to tie-wrap the wires in a bundle and move them out of the air path. I've even used cardboard walls inside the case to channel the air in critical areas. The glitchy operation maybe the cpu throttling back due to over temperature, but this would only be after warm up. It does sound like something may be running in the bvackground, looking at TASK MANAGER/APPLICATIONS and PROCESSES would reveal clues to sluggishness. Over clocking creates more heat, but there's more to consider than just the video card, There's the NIC, Hard drive controller and the memory to consider too.

Firstly remember that these CPU's are designed to throttle back when the reach a certain temp so that may be the reason why the System appears sluggish the CPU is running slower producing less heat to prevent its destruction.

If you are using the Genuine AMD Heat Sink the only thing that I can think of here could be that there is a layer of plastic protecting the Heat Sink Compound on a New CPU Heat Sink Combination and this hasn't been removed when the Heat Sink was fitted.

Just remember the more intensive the CPU tasks are the more heat they will generate and if they are overheating the slower the CPU's will run and this can produce Choppy out put from the CPU which can manifest itself in many ways audio being just one of them.

The AMD Quite & Cool is something that allows the temp to rise as it attempts to keep the fans quite by slowing them down to prevent excess noise so I would start by disabling this option.

As far as Air Flow goes it's a generally accepted rule to have the air entering the case at the front and being blown out the back so if you have the front case fan blowing out you are limiting the amount of air that can actually get into the case and adversely affecting the air flow as the air that is sucked into the case may not pass over the necessary places that need cooling even though you have a great deal of Air Flow through the case you will still get Hot Spots if the Air Flow isn't correct. Removing the cover will not help this as you are disturbing the Air flow even more so that the designers of the case may as well not have bothered to make allowances for airflow through the case the air will just be getting grabbed from the nearest spot available to the fans and could be very likely not allowing a constant airflow over the CPU's Heat Sink so that it is constantly getting cool air and not sucking back in preheated air.

I assume when you said you had just reinstalled Windows you meant clean installation of Windows. If this was not the case, please let us know.

The probable cause of the Windows being sluggish is CPU, Video card, HD, MB, or others.

1. CPU could be bad or CPU is getting hot. However, I do not believe the CPU temperature running at 150F will cause the system running so slowly. However, you should try a different and more powerful CPU fan and see if the temperature decreases and the Windows runs faster.
2. Video card may need to be replaced. The fact that the audio was glitch suggests that the video card may be the culprit.
3. HD may be failing. The best way to find out is to boot the computer with a Window 98 startup disk. If the FD is very sluggish to read the startup disk, the HD needs to be replaced.
4. MB may need to be BIOS flashed. Also check the BIOS settings. Makes sure the internal cache (L2 cache) is enabled. If you are not sure, set the BIOS to Default or Optimal.
5. Others. Make sure uninstall any PCI card (NIC, modem, USB, etc) and CD/DVD-ROM.

Go to http://www.amd.com/us-en/assets/content_type/DownloadableAssets/K8_Electrical_Spec_Rev_ENG.pdf for CPU temperature.

Because your system runs very slowly, it is not recommended to overclock your video card.

The order of testing is whatever convenient for you. 5, 3, 2, 1 (for CPU fan), 4 seem logical.

If you cannot decide which one, take your system to a reputable service place.

I forgot to mention that the MB itself could be bad or failing. This is why I put the order of testing of MB to the last.
