Dunno,if it hits the splash screen & quits or goes to black,then more than likely the hard drive is going bad. Doubt it's the power supply.

It could be an issue with your Windows install and or an external device plugged into the PC.
Unplug all of unneeded devices like printers and such. If this doesn't help try booting into safe mode. If this helps you may have an issue with either a driver, service or auto loading application.
running msconfig in safe mode and disable all not MS applications is a good place to start.
Try these options and post an update

My desktop dell dimension E521 won't come on. The power button just blinks green. A new power supply was tried but that did not work. What is it likely to be and is it gonna be worth fixing?


E521 motherboards are pretty reasonable: http://shop.ebay.com/i.html?_from=R40&_trksid=m570.l1313&_nkw=dell+e521+motherboard&_sacat=See-All-Categories so it is worthwhile to fix.
The 570 is a decent system although I am still an Intel guy myself

My dell dimmension e521 won't load to window screen.....i can't even get in to safe mode.......help


How did you try to get to safe mode. Have to tap F8 continuously for a while as soon as pc starts to boot. Holding key down might not work so it's better if you can keep tapping key quickly. If you have tried several times and can't get it to start in safe mode windows will normally put up an error screen to say windows didn't start properly with a few options. If you see this screen select last known good configuration and it might start to load windows normally if you are lucky.

Will not switch on. The light does not come on when plugged in at the mains


check the power supply, most have a little light on. might sound daft but if its a uk plug or has a fuse fitted in the plug that may have gone. try a different power supply, maybe take to a computer store and just ask them if they will try it on one of their power supply's as a test, of it works you can get multi fit power supplies quite cheap from well known auction sites. if it turns out it is not the power supply, it could be a fault on your main board, a fault with the power in socket (i have a toshiba and the pin inside the socket always breaks off, ive changed it several times) or more commonly to the older generation laptops, it ould be the battery. sometimes the battery completes the charging circuit, again knock off batteries maybe found cheap from well known auction sites, and alothough not always of great standards, they are better than paying toshiba for one and finding its a board problem.

Dell dimension issue: system is gone off all of sudden.. it looks like there is a problem with the add on card which consists 2 USB ports and microphone and headset speaker.... but this card is connected...


It seems likely that you have somehow dislodged/interupted the graphics card GUI, which enables windows to come on the screen. Without this, the system will not boot properly due to the fact that your CPU is looking for it and cannot find it. You may want to double check to see if that card is in properly. Also, did you download driver for the new card? If not the right driver, it won't work. Another thing to check could be the IRQ I/O addresses (go to device manager/advanced) If they are not assigned a number, they won't work either. You can always hit F1 (it may be different on your comp, try f8 or f12) after you hit power switch, to see if it will give you the boot info before your OS starts up. Of course, you will not be able to see it if you have no video. Try to listen to the comp when turning it on. How many beeps does it make? It should only make 1, if it is making more, or a long one, you can find out problem that way.

The laptop doesn't boot up always.


I would try the following:
1. Remove the battery completely. If the computer boots properly several times in a row, then the battery may be causing the power supply to do strange things.
2. If you have experience removing laptop components, try removing the hard drive. Because you say the screen goes black (I assume the system powers off) sometimes after the HP logo, I doubt its Windows or a software issue.
3. If HP has a diagnostic CD you can boot to, try that.
4. It may be the power supply acting up. If it charges the battery, and if you can boot to Windows with the battery, try getting a new power supply.
5. Otherwise, it may be the motherboard of the laptop.
