SOURCE: dell dimension 5100 won't power on

might be a problem with the power button...try exchanging the power adapter and the reset adapter in your motherboard...this would become:

RESET BUTTON: as power button.

view your manual on where to find this adapters in your board.

SOURCE: hp pavillion desktop will not

Step 1 : Turn off the system by pressing the power button for 5 - 10 sec until the power LED is off. Removed all cables including the power cable (Exclude monitor cable and KeyBoard/Mouse).

Step 2 : Press power button for 5-10 sec again to drain fela power.

Step 3 : Reconnect the power cable at the back of the tower/computer and power on the system.

**If the same problem exists, Call HP tech Support (800-474-6836) because there is a high possibility that you have a bad Motherboard or Power Supply on the system.

Your power supply is bad--you will need to replace. I suggest looking at tigerdiect for a replacement.

Power supply in HP slimline s7310n


It sounds like the CPU is over heating. It probably has poor ventilation. Unplug the unit and open the side panel. Carefully vacuum all the dust inside. Be careful not to damage any electronics. You can use a small brush to loosen the dust before vacuuming. Good luck!

If you didn't accidentally unplug the four pin connector near the CPU, you need to replace the power supply. This is actually a fairly common occurrence with the cheap ATX power supplies being tossed into systems these days.

Hp pavillion media center a 1540n motherboard.....computer cpu fan runs, power supply runs, when i hold the switch it won't power-down unless i un-plug computer....no video (not even bios) does this mean...


Hello!

Try clear cmos, if the motherboard bad you must wait so long, maybe you can turn on computer, and they can work perfect, but when you turn off computer on power suply, you can´t again turn on computer.
If this so you have trouble with motherboard.

I have an HP Pavilion a384x. It will not turn on


First with the computer turned off make sure the switch on the power supply is set to 115v.

If you turn the computer back on and you still get a flashing green light on the back of the power supply and a constant light on the front of the computer with no video, then try replacing the power supply with either a new one or a known working good one.

If that doesn't do it then it has to be the motherboard at that point.

Keep in mind normally on those power supplies, the green light should be constant. So it has to be either the power supply is bad or the moterboard is bad and you'll know when you put a new or known good working power supply in the computer.

Probably bad memory or loose CPU module. First try removing and resetting CPU. You'll need to remove Keyboard, Palmrest, and heatsink and shield beneath Keyboard. You'll need a small Phillips screwdriver to remove screws and small standard size screwdriver to loosen screw holding CPU. After removal/reset, put everything back together and try powering back on. If still same problem, replace memory located on bottom of LT located behind door. Also, you may have a memory module located under Keyboard next to CPU that may be bad.
