Question about PC Desktops

1 Answer

Rebuilding PC I have transferred all parts of my PC from the manufacturer's slimline case to a standard case with a new quieter CPU fan.  It powers up for a few seconds and then shuts down.  Why might this be?  Can you help?

Are you sure you connected all the power cables from the power supply that need to be connected to the motherboard? Please tell me what motherboard and processor you're using so I can further assist you.

I have a hp slimline 3100. the cpu fan runs fast everytime i open a program or play a cd. it speeds up the slows down. sometimes it runs really fast, then the computer shuts down. whats going on?

This is an indication of overheating within the PC. Open the PC case and clean all the air vents. Take the heatsink and fan off the CPU and give it them a good clean. Put the heatsink and fan back on to the CPU and start up the PC. check that the fan on the heatsink is running smoothly.
Also, make sure the vents on the power supply are clear and the fan on the power supply runs well.
If you go into the BIOS setup, you may be able to monitor the fan and the CPU temperature.

I have an Hp pavilion slimline s3100n pc and after a while, it just shuts off with no warning whatsoever. When I try to turn it back on, it just shuts right back off. It's like I have to wait for it to...

Verify your fans are for the CPU and case are moving. You can remove the Pc cover and turn on the Pc. Watch the cooling fan on top of your CPU heat sink, it should begin spinning when you turn on your PC. If it doesn't then with the PC unplugged, make sure the connector for the fan is seated properly. From behind the PC you should be able to feel the Power Supply cooling fan moving air. Either of these could cause your PC to over heat and shut down.

Very noisy fan

You can try using caned air. turn off and unplug the computer then used the caned air on the fan to blow out any dust. plug it back in and power it on and see if the fan is any quieter. If not then it could be that the fan is going bad and may need to be replaced. Most computers will have a coupl of fans, case fans, CPU heatsink fans, videocard fans, power supply fans, so you will probably need to open the case up to get to all of them and make sure they are clean.

I have an IBM ThinkCentre PC, that the CPU fans often spins on high, even when CPU is idling. I have used Dust Off spray to try to clean fan, but obviously have not gotten all the dust out. Is it possible...

Yes, you can take off the fan. They are usually screwed into the heat sink or are clipped to the mainboard on top of the sink. Just be careful if you do this as it's easy to accidentally pop off the cpu and bend some pins. You may want to invest in a quieter fan for both the cpu and case if you already have it out.

My HP Slimline Desktop s3120n turns on and as soon as goes on it turns itself off.

it seems your computer needs cleaning and servicing, my advice is to open your pc and use dust cleaner,you can buy a can from any computer outlet, spray all the dust out also all fans,the heat sink on the CPU,make sure also the fan that is connected via the CPU,I believe dust has accumulated between the fan and the CPU,by this the cpu cannot read the from the hard drive all because of so many dust that has accumulate between the cpu, it hard to read the data from hard drive and CPU.
hope this work for you.

Won't Start

This happened to my to my HP Media center Edition PC. I'd have to unplug the power from the outlet, let it stop flashing and the power up again. It would run for a short time and then shut off with the annoying amber / blue flashing light.

I found it was a heat problem on mine - specifically, the CPU cooler. After shutting down and opening the PC, check to see 1) if the CPU fan is running smoothly and 2) if there is a lot of dust and dirt on the CPU cooling fan and heat sink (and rest of the case for that matter).

Gently clean / vacuum the insides of the case AND power supply as best you can. Carefully vac the fan blades and heat sink to clear the dirt and dust that prevents the heat from being blown away by the fans.

When complete, you might even want to take the PC outside and reverse the vacuum so that air can be blown into tight places in the case. A can og compressed air can do the job instead, too.

Reassemble and start up as normal. Good luck!
