Hi, I'm not very technical on all this but I'm going to try to run through as well as I can what the symptoms are of my computer.

Firstly, I came downstairs two days ago to find my computer had frozen. Nothing would react, mouse, keyboard, power button on computer (to click fast to get the shut down menu).

So, I thought "OK, I'll kill the power, restart it, it'll be fine" even though I hate doing that.
I killed the power, turned it back on, and it got to the first image in DOS, but before any text came up and froze again. So, after waiting awhile, I decided to kill the power once AGAIN and try to get it running. Restarted it, and this time it loaded past the XP startup logo, with the progress bar, and froze just before task bar etc were loaded, so before explorer.exe loaded.

Again, I let it stand for about 5mins to try to see if it would do anything, but again nothing was reacting. Reluctantly, I held in the power button AGAIN to kill it and try to restart it. But, now, nothing happens. The computer starts up, the HDDs spin up, fans start running, you can hear the CD-ROM drive react quickly but no signal to the monitors.

My motherboard, a DFI LanParty UT NF4, has 4 small red LEDs showing the startup sequence and faults. All four glow as it starts up but none die off, indicating, supposedly, that the CPU is not responding. Can it be that my CPU has failed?

In addition, my GPU (HIS Excalibur ATI Radeon X1900 XT) has got two red LEDs on it, one for Power and one for "t_fault". Both of these also light up. I do not know, however, if this is what it normally should do as it starts up. I have tried reading on other threads that apparently these two LEDs on the GPU are not reliable, I don't know though.

Having tried pretty much everything, I also tried to follow the manual to the motherboard to reset the board without resetting the CMOS, but this did nothing so decided to also reset the CMOS on the motherboard to try to get the system to restart, but this had no effect.

My complete system config is;

DFI LanParty UT NF4
AMD Athlon 64 X2 3800+ S939 OEM (O.C.'d -> 2.4GHz)
HIS Excalibur ATI Radeon X1900 XT
2 x SP2504C 250Gb 8Mb Cache SATA II OEM HDD
NEC ND-4570
Hiper HPU-4K580 Type R 580W Modular ATX2.2
Windows XP
2x Viewsonic VE710b 17" LCD Monitor - Black

Any suggestions would be appreciated, I will try to reply as well as I can. Thank you.


P.S. This system has been running flawlessly for well over 17months, so there was no new installs or hardware installs which may have caused this, to my knowledge.

After you reset the CMOS, you must load the setup defaults, "Exit and Save", go back into BIOS and set all the values to where they were, "and "Exit andSave" again - you've done that, correct?

Hit F8 during post, and try loading "The last known configuration that worked".

If that doesn't work, re-boot, hit F8, and choose "Safe Mode" - if that works, it might be one of the drivers, or malware. The hardware is probably OK.

If that doesn't work:

Try the "Seatools starter edition" (or equivalent for your HD manufacturer) and conduct the troubleshooting of your Hard Drive.

If that's OK, try booting with 1 RAM stick only.

I would see if all that works before going any further.

Good luck!

Sorry I may not have been entirely clear, the computer does not get that far in starting up anymore. I cannot get to the BIOS because as soon as the system starts up, there is no signal to the monitors, nothing is being sent and the system does not even DOS. I cannot change anything or get into any sort of menu, setting or anything.

I have tried to boot the system on 1 RAM stick, each variation, with no success.

Try a different Video Card - that would be my next guess. Or the Power Supply.

And if you're not runningg in RAID, unplug one of your HD's.

I have attempted both now. All plugs and connectors have been cleaned up properly and I have tried running the PC with a different GPU but I do not have a power supply to try. Also I am running the system in RAID0 configuration so am unable to unplug the HDs.

So far, no luck.

I will try that asap, I just need to find replacements. I don't fancy buying new components before I know exactly what's causing the problems.
