Question about Sony VAIO VGC-RB42G PC Desktop
I moved my computer to a new spot, and when I did I vacuumed off all the dust off the side of it. When I plugged it in it will not power up. The power supply has a green light on it and it blinks, the motherboard has a green light and it blinks as well. It also has a ticking sound, kinda like a watch. I have unplugged the power supply from everything inside and replugged it back in, took the ram out and put it back in, checked the battery and it is good. Any ideas?? It was working fine up until I moved it.
I had the same exact problem for the same exact reason. Plug the power cable into the back. Open up the side of the case and unplug all the wires that the power supply plugs into. The motherboard, harddrive, cd & dvd drives, everything. wait about 10 minutes and plug them back in, plugging the BIG cable that connects to the motherboard back in LAST. This will make the light go from blinking to solid. I think it is a safety? to protect the motherboard from damage.

Plug your computer back in and turn it on if the power supply fan isn't working correctly, then that would be your ticking sound and also the computer will not turn all the way on if there is something wrong with any of your fans.

The CPU fan is what keeps the processor of your computer cool while the machine is running. A noisy fan on the CPU can be very annoying for users of the computer. However, it can also be a sign of a dangerous problem in your system. If the CPU fan is making noise, it is probably not running at full capacity to cool the processor, which leaves your computer open to problems involving overheating of the processor. An overheated processor can be permanently damaged.
Unplug the computer from the wall. Remove all devices from the back of the computer and move them away from the area where you will be working. Either wear an anti-static wristband or discharge any static by touching a metal part of the computer case.
Remove the screws from the back of the computer case with a screwdriver. Pull the sides of the case off and set them aside. Lay the computer on its side so that you can easily see the motherboard and all parts connected to it. Locate the CPU fan; it will look similar to the image in the introduction.
Ensure that no cables are hanging low and touching the blades of the CPU fan. Move any cables or other parts that could be hitting the blades of the fan causing noise. Tuck these cables and wires into an area where they cannot interfere with the CPU fan.
Use a cotton swab to remove any dust that you can from the blades of the CPU fan. Don't use any harsh solvents or other cleaners that could drip down and damage the processor through the fan.
Spray the compressed air into the fan to move the loose dust away from the processor fan. Move the dust into an empty section of the case with the canned air. Don't spray the air too hard or else you can spread the dust into other places in the computer.
Use the vacuum cleaner to vacuum up the dust that you moved away from the CPU. Place a crevice tool or other attachment onto the hose to reduce the size of the opening and help ensure that you only remove dust.
Replace the computer case. Plug the computer and all devices back in. Boot up the computer and check for reduced CPU fan noise.
