When I plug the unit into power, the CPU fan runs very fast but no boot, and then when I press power on the fan slows down and the PC boots normally. It shuts down in about 30 minutes with no sign of...


Sounds like you are overheating. One way to tell if it's overheating is you say it will run for about 30 minutes then shuts down. When it shuts down try rebooting to see if the boots successfully. If it fails to boot successfully right after it shut down then you are probably overheating. If you wait awhile to let it cool down for 30 minutes or so and if you reboot and it does it successfully you definitely have a overheating problem. If I remember correctly all those compaq sr series have loud and fast running fans. Computers overheat because of three reasons for the most part: 1) A fan has stopped working. 2) The Thermal Paste on the CPU and Heat Sink has dried up or is not thick enough to keep the unit cool. 3) Dust has clogged the fan vents and inside the computer. Fortunately for you desktops don't have to be completely disassembled like laptops to get to the fan, CPU and heatsink. Just pop the case and you'll see the components attached to the motherboard

It keeps shutting itself off ?


When does it shut itself off? Is this happening time you press the power button and during the boot cycle it shuts off without completing the boot to windows? If it shuts down after you've worked on it for a while it could be that it is running hot. If you let it sit a while to cool off then press the power button, if it completes the boot cycle and allows you to work it is definitely running hot. Normally when they run hot if you immediately try to reboot, it will fail. If you let it cool off it will boot successfully. Computers run hot because of a fan not working, dust clogging the fan vents or the Thermal Paste around the CPU and Heat Sink has become hard or too thin to keep the unit cool. If it's not running hot you might have a power supply or motherboard issue. Try removing the power cord and press and hold the Power Button for 30 seconds to release any Static Buildup. Then plug the power cord back in and try to reboot.

Acer Aspire t690 Desktop Freezes or reboots with in minutes of start up...Running Windows Vista. Help???


It is possible that your computer is overheating and is shutting down to prevent it from doing any harm to itself.
Make sure that all fans are clean, there must be no dust present as it hinders airflow!!!
Install as many fans as possible. Computer temps should be in the region of 30-40 degrees centigrade. To avoid CPU throttling, where the CPU slows down to prevent frying itself.
Please take the time to rate my expertise.
Thanks

Gateway gm5442 very slow to boot, 20 to 30 minutes.


You said you tried different CPU, but it was the same motherboard, right? Maybe the motherboard speed (data bus, etc.) is just slow. Otherwise, there's not much left to try if the hard drive works OK in another computer and you've tried upgrading the memory, CPU, and power supply.

My gateway 510x keeps shutting itself off. Sometimes after 5 minutes of booting up sometimes after 30 seconds. What could be the problem? Tried removing dust from the inside but that did not help.


sounds like your processor fan shut down and now your processor itself shuts off when it begins to over heat replace fan asap and don't keep trying to turn it on because you'll burn it out

Computer powers on but shuts off by itself after about a minute.


Take the left side panel off and check the CPU fan for dust build-up.
You can use some canned/compressed air to clean it. Be careful not to knock off any components. You can also re-seat the RAM/ memory sticks while you are in there. Good luck!
