XP "Starts up" but shows no display

[Steeevoe]

-When we turn on the computer, the extractor fan and CPU fan starts up.
-Keyboard lights flash once, but you can't turn them on by using caps lock.
-Green power light shows.
-DVD Drive opens and closes


We have changed the PSU, monitor cable, monitor, and used the on board graphics with our graphics card removed. Doing these has not changed anything. The monitor just says "no signal"
We have also removed the CMOS battery for a minute and put it back. This also did nothing

Our Setup:
Windows XP OS, intel Celeron D, 512Mb RAM.

Please Help!

Hi,
How about the ram chips, try removing one by one and use them intersectively, see if it will change anything, if it doesnt, then have the processor out and fireup the board, then after, insert the processor and fire it up without the ram, all that should give u a warning alarm, then after proving that the board is fine, with those alarms, then u can instert one ram, at a go, but make sure u interchange them.If it fails, let us know for further help.

The alarm sounded when only the CPU was in, without the RAM.

After moving the one stick that was inside the RAM about to the other slot, the PC started up, but once a user was loaded, system crashed

After moving a stick from a different machine, it loaded up and crashed at user screen

Restarted Comp, loaded user, then restarted itself and crashed.

Restarted Comp, nothing happened except for the PC fans spinning.





Put the stick of RAM in our other computer from the one that was originally misbehaving, now it wanted to boot from disk, replaced the RAM, now booting from disk :S

Don't know if this PC wanted to boot up earlier today, we haven't had it on.

Some kind of hard disk problem. (or he O.S. that's in it). You're sure the drive is shown in the BIOS? You have checked the hard disk cable? If you have the program disc you will (hopefully) see 'hit any key to boot from CD": start the installation process: when the screen is at "what partition do you want to install Windows on" ?...........select 'repair' the O.S. Good Luck.

Thanks, the system is just doing that now, looks hopeful and looks like it will get running again


The other PC is still not running very far. Any ideas why? Is the stick of RAM we were using corrupt and thats why when we put in the now working system is made it pack up?

Otherwise, my IT Tech at school says he is willing to have a look at the unit. Fingers crossed he can sort the PC out!

Hi,
That is address allocation problem in the ram, i suggest if u have another chip, then replace it with another or best way is to do a ram test, so download this software called Memtest86, unzip and burn it on a cd-rw and startup the machine with that defected ram and follow the options.if by any chance it show u errors in red, then dont waste yo time finishing the process.Just buy a new one.
