1.Remove all the power plugs and connectors.
2.Press the power button for 45 secs.
3.reset and refix all the connectors.
4.check if it is working otherwise this is motherboard issue and u can confirm by removing the smps and shorting its any black and green wire
if it fan moves continuously then check with minimal boot(removing all add on cards.)

Hiya

it seem as as tho ur cpu is over heating...... take the case off and have a look to see if the cpu fan is turning if not theres your problem......

if it is turning it cud be the fact that the cpu isnt getting enuff power or too much...

INPUT2: HD15 keeps coming up on my screen. i cant get through it. do i need to buy new input2: HD15 cable? the monitor is sony make and the hardrive is fujitsu siemens computer make


more information is needed for this question to be answered properly
im going to guss that this is your conection cable from video card to your monitor
try disconecting and reconecting the cable making shur that the cable is firmly conected at both ends
its posible that part of the tower case is preventing the full insertion of the cable into the socket
cut away 1/8 inch of the ruber shielding around the pc side of the cable so that it can fully be inserted into the conection
check that the pins on the male conection arn't bent or broken off

also run your closed hand down the cable itself checking for cracks cuts or breaks in the cable

if any problem is seen replace the cable if any pins are broken off check the femal reciver for the broken of part of the pin so as to not damage anothere cord
good luck

Problems loading OS in Gateway desktop


Normally installing the os on a different mechine, and then putting into another pc dosent work.

If the hardrive is the oringinal drive, which came with the system, and you want to install xp on, you will have to use a dos disk with fdisk on it, delete all partitions on the drive and create a new partition, then start loading windows, it will give you the option to format the drive for nt(ntfs) file system and setup windows.

If you do that and it still gives you protecting files error, you will have to take the side panel of the computer tower, unplug from the mains and take the cmos battery out for about 30 secs, put the battery back in, plug in the mains and reboot the computer, start loading windows again
Hope this helps and post back if you need further assistance.

My monitor suddenly lost signal and hasn't returned


do you mean the processor fan that is located near on the left top corner on the motherboard? if that stopped working then turn of your pc immediately. probably the cpu overheated. if that fan does not work replace it immediately as it will burn the cpu.

When i turn the tower on the fans start then a little red light flashes but then it turns off after few seconds ? please help it is a Packard Bell


Is the Fan on the CPU running for that quick moment? If not, you need to find out why not and fix it or you'll burn out your CPU. If it is, Jumper your Bios to CLR for 30 sec. then back to normal. This may help you boot, but you will have to set the time and date.

Turns on, cd light comes on but cpu does not boot and light does not come on, the monitor says "no signal" . Cpu dpes not shut off at the button anymore. I have to unplug it to turn it off. HELP! By the...


You should get it repaired. That is likely a power supply failure. Yes, I see you have power, but I still say power supply, because there are 2 types of power: There is Motherboard power and there is CPU power. If CPU power is not correctly flowing, the CPU will not activate. If the CPU is not active, the board will not process any information, even though the board is receiving power. Power supplies are not hard to replace and are usually about 40 bucks
