Hi,

i woke up this morning, turned on my pc and everything started up. However, none of my monitors come on but the system is booting up. i checked inside the desk top and there is a red light showing near the cpu tag.

any advice
 
ok system spec...

Asus Crosshair IV Formula Motherboard
AMD Phenom II X6 1055T
8GB Ram
Nvidia GeForce GTX 460 1GB Graphics Card

Bare in mind i did not build this system
 
If it halts on your CPU Led its not posting past CPU initialisation.Reset your BIOS with the switch on the back. If that does nothing, make sure all your PSU connections are in place right, especially the 8 pin to the top left of the CPU.
Hope you get sorted,
Dave.
 
Crosshair IV doesnt have onboard gfx and if its halting on the RED CPU Led, theres no way of getting in BIOS as its not initializing the CPU correctly, reset BIOS make sure everything is seated right, take componants out to the Bare minimum. Is about all you can do when that LED is lit.Thats aslong as were talking about the LEDs that are on the right side of the board, around the 24 pin connection, there is another CPU Led that relates to voltages that it is set to and RED would mean high voltages being used, but thats to the left of the CPU.

Right, randomly it comes back on asking for a boot device but i guess thats the OS disk or the original boot sequence.

everything seems to be booting up fine..i've trid resetting the bios that doesnt help and im sure everything is seated fine.
 
You sure its the CPU Led its halting on everytime?As just noticed you said near the CPU tag, theres 3 other diagnostic LEDs there too so does make a difference. If its intermittent id start stripping uneeded parts out and see if it makes it any better.
Yeah the asking for boot device is just the boot device priority under the boot tab in Bios.
Whats your PSU like btw?

the PSU is a stealth X Stream 2 600W..anyway, to be fair ,ate i dont feel comfortable taking it apart im not that tech savvy. To be fair i dont know wether its the CPU led thats all i see red.
 
If you can count the leds upwards, it goes CPU, DRAM, VGA, Boot Device.
If you can see which one is lit it helps a great deal with that board.
Fair enough if you dont feel comfortable with taking parts out, maybe its a BIOS setting (problem is BIOS doesnt change intermittently but could be a setting not 100 percent right i suppose).
