Hello,
First of all, not all the time memory is bad it gives a beep. So you might still want to verify that it's not the memory. Try the memory in another cpu or try another memory in your cpu.

If you have verified that the memory is not the issue, then your next culprit is the video card. Make sure the video card is working. Take it out and clean the contacts with a clean piece of cloth and then reseat it properly.

Please let me know when you have verified the above recommendation and if it works or not.

Thanks and good luck
Lolita

SOURCE: PC wont boot cpu fan runs extreemly loud and fast.

You may have a failed motherboard or bad/weak poswer supply unit (PSU) then. Failure of motherboards is usually due to breaking capacitors. A few years ago a capacitor company stole the "recipe" for making capacitors from another company and tried to make their own, unfortunately they did not get the ingredients right and the capacitors started breaking after 2-3 years of use. They sold these capacitors at very cheap prices and a lot of computer companies and power supply makers bought them. The DELL GX270 and GX 280 were the main DELL models affected by this situation. This is easy to diagnose. Look for capacitors (caps) (they look like little tiny soda cans) on your motherboard (mobo). They should be perfectly flat on top and not bulged or swelling or leaking anything. Make sure you look under the fan shroud. Most of the bad ones had either a plus + or X on the top - depending on your interpretation. There are a few companies that will repair broken capacitor issues. If it has recently gone out of warranty you could try to contact DELL to see if they will ship you another one. I was able to get them to fix a couple of mobos out of warranty, but that was two years ago. To eliminate some other stuff you could remove the memory and disconnect all the power plugs from the drives and then try to start it up. If it does not change the behavior at all (no beeps, no change in flashing lights) then you probably have motherboard or power supply issues. Make sure when disconnecting the memory chips (sticks) that you touch the metal on the inside of the case first to discharge static electricity. If it does change the behavior add 1 component or item back at a time to see what you can find out. Post back with what you find. And remember a bad PSU does not mean no power, just not enough to run the computer. If you change out the PSU, the one that you replace has to have the same or greater output watts?

SOURCE: after installation no video output

This isn't a RAM issue if you're getting a clean POST. Make sure that in the BIOS you have onboard video disabled.

My computer dell gx 620 desktop fan is running fast and it keeps on restarting and hanging especiall during heavy games and also videos and the fan is running fast


When the CPU overheats then it will shut down (i.e. thermaloverload) and won't boot up again until it has cooled down. If this is theproblem is not fixed then the CPU will eventually fail.
A faulty fan causes the problem or the fan and heat sink assembly are cloggedwith dust.
Check the CPU fan to see if it spins freely, if not replace the fan.
If the fan and heat sink is clogged with dust the remove the dust and make surethe vents are clear and dust free. Use a can of compressed air to do this.

Hi, I need standard spec info of VGA built on Asus P5GC-MX 1333 whether 64 Mb or 128 Mb. Many thanks & regards, Richard


you can use up to a maximum of 224 mb of your computer's RAM for the onboard video chip to use. You can install a video card with any amount of memory (which would give you a lot better video performance).

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.

GA-7N400 Pro2 at startup i hawe long separate continus beeps


Possibly Ram, try and see if removing and replacing helps
Other causes may be voltage issues ( check the bios and see what the various rails are telling you)
eg: there should be readings for 12 volts 5 volts and 3 volts, if any are + or - by 10%, there is an issue with the voltge controller. You might want to try a replacement PSU?

After this.. bad video ( check by installing a video card)
Temperature warnings ( check in bios to see under PC health status) what the cpu and board temps are running at, if above 70 degrees...overheating issue or more likely at start up, board thinks that the CPU fan is not running fast enough or not working. If fan IS working, you have a problem with the CPU fan sensor, will need to replace mobo

I have a HP M1270N Media Center PC. The CPU Fan


The CPU fan is designed to run constantly to prevent the CPU from overheating. The speed depends on temperature condition of the room; slow in cold and fast in a hot room. However if you suspect that it runs too fast them try re-seating the CPU. WARNING: Re-seating should only be done if you are know how to do; don't experiment.

If it is running noisy, you can apply one or two drops of machine oil to the fan's spindle.

Other reasons include deposits of dust; use a blower to remove dust from the heat-sink.

To make sure you CPU is not in a critical state, log in the BIOS and in the hardware monitoring tab check the CPU temperature. It should be near 60 deg Celsius or 140 Fahrenheit.

One thing more, do not apply thermal grease in excess; its a conductive compound and can short the motherboard if it melts and deposits on the motherboard due to high CPU temperature.
