DELL Inspiron 9300 1Gbyte RAM, that has a CPU race condition

I have a DELL Inspiron 9300 1Gbyte RAM, that has a CPU race condition.
CPU running at 100%, the fan blowing at max speed. It unable to service any other tasks, basically unusable.
At first I thought it was a virus. Much of the system time was spent by the antivirus software. But the condition persisted after the virus scanner was suspended. Rather than trying to untangle a bad virus, I reinstalled the entire OS going from XP SP1 to Vista SP1.
While it is at least usable now, the CPU continues to race and the fan won't step down. Is there a hardware issue that can cause this?

Do you still have the Dell Resource CD? If so, run the 32-bit diagnostic tests by inserting the Resource CD or Drivers and Utilities disk and press F12 when you start the computer (as soon as you see the DELL logo). Then boot from the CD-ROM. Run the Express Test. Check for error messages. Go to and search for that error message or codes.

My Dell Inspiron 1525 keeps turning off while being used. It is usually when trying to play a online game or on Facebook. Could it be overheating? The keyboard seems to be getting a bit warm, but not any...

Download CPUIS's hardware Monitor ( it's free). Install and run. If the CPU temp gets higher than 60 C when idle or 85 at any time, you ahve an overheating issue. If CPU tem reaches 100 C, windows will shut down.

You may need to clean it up if you haven't done so in a while. Turn the laptop off, remove the AC charger cord and the battery. Remove the bottom cover and blow compressed air from a can (compressed air cans can be bought at Walmart, Best Buy, Radio Shack, etc.). Be sure you remove all dust and lint. Check the fan can be easily moved with fingers. Replace cover, battery, AC charger cord and restart laptop. Check temp again.

BTW, if you're running 3D games, online or not, get yourself a desktop. Laptops are a bad choice for gaming, since videocards can reach 100 C during some heavily demanding 3D games.

My laptop overheats and cpu usuage at 100%

When the processor overheats it slows down to lessen the amount of heat generated to prevent damage. Things you can do, is use canned air to blow out the vents (Both intake and exhaust) several times. Also make sure the fan is operational (You can run the fan test) The heatsink may need replacement if the tubes have lost their vacuum or you can add some arctic silver heat compound to mitigate heat

My dell inspiron 1300 shuts down automatically and doesn't turn on after a few minutes. I believe it has something to do with it heating?

I think your right.Heating most of the time will cause a premature shut down.It may be your ram getting hot or video card and possibly your HDD.The ac adapter could also be overheating/going bad as well.You could blow it out through the vents, with it off and unplugged.You maybe able to get a notebook cooler to use with it.It MIGHT help.If you could get it apart and blow it out ,you may increase you chances.

Dell inspiron 8500. fan comes on high speed & system locks up, requiring turn-off at switch & reboot. what gives?

Normally fans racing at full tilt on boot indicate either a severe cooling issue or an indication of a NO POST.

See if you can take some canned compressed air, can blow in and out the intake and exhaust vents for the CPU cooling and see how much dust you can get out of the system

If no change, then remove all times you can tale out (Battery, RAM, WIreless Card, Modem, HDD< OPtical Drive) and see if the system has any change in indications.

If no change, likely a motherboard. If changes, add RAM back, see if system will post and you can access BIOS. Continue adding parts till you ID a faulty one.

2 ghz processor running at 220 mhz


Have you tried right clicking on the desktop (opening Display Properties), clicking on Screen Saver tab, Clicking the Power button, and setting the power schemes to Home/Office Desk? If its set on laptop it will reduce the processor speed when running on battery. I have noticed that even with it plugged in that some times it will run at half processor speed. Try that out.

Have a great day,

Inspiron 5150 fan continously running

Dell Inspiron 5150, has overheating problems. The position of the fan is a problem.Also,don't press of the left upper corner of the laptop.Here's an excerpt from a wikipedia article: "The overheating problems on the Inspiron 5150 model was due to the position of the fan and fan-vent and the way in which it vents air through the CPU's heatsink.[citation needed] The fan draws air from underneath the unit and vents it through the rear after passing over the heatsink. However, the unit also sucks up dust from underneath it. Over time a buildup of dust constricts the airflow through the unit, reducing cooling. The airflow is perceptibly diminished. A simple test is to place a hand near the fan vent; when the fan is running at high speed there should be a good flow of warm air. Heat will also build up along the top of the unit near the LCD display and left toward the optical drive. Users may notice this while typing. Performance may also suffer, with jittery game movement and slow Windows performance. Some systems may experience jerky reactions where the unit goes into an almost slow-motion phase for short periods of time. Continued operation in this condition may lead to overheating and could result in permanent damage to the CPU, GPU, motherboard and other internal components. To remedy this the unit must be disassembled, the dust removed, and fan operation checked. This problem not uncommonly results in a CPU temperature-increase of between 15-20°C over an normally functioning unit. Further temperature increases may damage the casing of the unit."From Wikipedia article"Dell Inspiron" under problems Hope it helps -CG

Laptop running hot - Fan cycling on and off every 10-20 seconds

My guess is that CPU fan, it there is one, is not working properly and your computer is heating up. Is it turning off, too, occasionally after a period of time? Suggest a new CPU fan.

Dell Inspiron 1100 Memory speed

You need to look at the memory card(s) you have and only the same pin memory will install. Faster memory isn't as important as the maximum amount you can add, since your cpu can't run any faster, but windows can use the extra ram and avoid disk-swapping which is slow.
