After powering on monitor says no sync


I've almost the same problem. When the system turns on the monitor doesn't sync. After a variable trials with down/up the sync is enabled and the computer starts.A very clear event occurs : when the monitor can''t sync ( and system doesn't boot)you can hear very clear a high fan rotation. When I look/hear in the system the Isuspect the cpu fan. The system boots ( monitor syncs) when the fan rotationgoes from high to low. So the system hangs on an internal check on the rotation speed of the cpu fan.I've googled a lot , but until now doesn't find an answer . Possibilties which I think about : replace cpu fan , clean cpu fun ( but it looks clean).I cannot measure the fan rotation speed when the system is hanging. At normal rotation all info can retrieved witth the program cpu-z.Did you already have a solution ?

HP Pavilion a330n - Computer does not hold power or turn on.


Hello Martin,If the CPU fan is faulty and not running the CPU will over heat and shut the computer off as a precautionary measure. If not the CPU would damage itself and not work anymore.You need to run the HP diagnostics on your Desktop to see if it is really the fan that is causing the problem. Go to http://h10025.www1.hp.com/ewfrf/wc/softwareDownloadIndex?cc=us&lc=en&dlc=en&softwareitem=pv-25052-2 and download the .iso image. You will need to burn that to a CD/DVD and boot from it. Here are the instructions :http://h10025.www1.hp.com/ewfrf/wc/document?lc=fi&dlc=fi&cc=fi&docname=c00471587If it is the fan and the PC is under warranty, contact HP. If not, you will need to replace it.

Sony KDS-R50XBR1 /(2005) Red stand-by light blinks 4 times.Tried new bulb (Philips) 1 week ago ,same problem as before .Whole new light engine replaced two yrs ago by sony.What happens is it will turn off...


The error code of 4 blinks indicate a fan problem.the fan is slowing or internitantly stoping. the fan is stallling. or the fans not getting power. Always rember anything that moves will eventally stop. this fan is on all the time. also there more than one fan. Listen closely to hear the fan. The fan is not difficult or exspensive repair.

HP media center pc ,1170n will not boot. black screen. You can hear the fan come on but black screen.


Sounds like a capacitor has blown on the motherboard, but before condemning it, check the following:
1.) Does the CPU fan turn and does the heatsink get warm after a few minutes?
(This indicates that power is at least getting to the CPU
2.) Check connections of ALL the main power connectors (ie: the 20/24 pin plug to the mainboard and the smaller 4 pin plug to the mainboard.
(If not firmly inserted will stop the board from firing up)
3.) Check the graphics card is firmly seated and test with anew graphics card to eliminate the issue being with the graphics card / check tightness of the VGA cable to monitor and card
4.) Remove all but the main power and 4 pin power plugs and try rebooting to eliminate hard drive or DVD drive failure
5.) Remove and replace each ram module in turn try booting in between
6.) If you have a spare PSU, replace the existing one and test the board using that, sometimes the PSU appears to work, but lacks power to fire up the board.

After all that, you are down to the mobo or CPU, you can try a new CPU, but I feel that the issue is with a blown capacitor or a burned circuit trace, only close inspection of the mobo will reveal bulging, leaking or blown capacitiors (small cylinder like things on the motherboard)

Computer just turnoff suddenly


Could be one of two most common problems?
#1
Have you ever replaced the CPU Cooler (Heatsink/fan)?
CPU Cooler fan may be working, Heatsink dirty.
CPU is over-heating = mainboard turns off
Replace CPU Cooler
#2
Power Supply fan not working causing partial failure on 5volt or 12volt side.
Replace Power Supply

There are more causes but these are most common for short-time boot problems.
Another could be hard-drive, but that wouldn't shut system down like first two would.

L7VMM2 wont boot (no post) plz help


Sounds like the CMOS battery on the motherboard needs replacing...i would try clearing CMOS first, replace battery and test voltage at the CPU (through the BIOS) If that dosen't help you likely have faulty capacitors.
If you get it to boot, im sure drivers and BIOS will need updates if it's been stored 2 yrs.

Computer turns on, but does not boot to XP


Generally, fans are controlled by heat readings...something to check is the operating temperature that is shown in your BIOS when you boot up...(access your BIOS by tapping on the delete key, or F2 key while booting)..if it goes over 70C real quick then there is a CPU heat dissipation problem, which would cause the fan to run like this i think that it is more of an issue that your CPU died...has your machine taken any kind of hit or fall that might have loosened things?...or perhaps the heat sink compound between the heatsink and CPU failed.....
but it also could be a dead MB
