Right, long one this.
For awhile i've been getting blue screens and to resolve it i tried updating all the drivers/bios etc. Upon completing this the computer worked fine. Today however it wont boot up at all. Upon turning the desktop on the cooling fan kicks into overdrive and the 3 and 4 lights are flashing on the front of the desktop. Also nothing comes up on the screen and nothing i do will change this. It will then just sit like this until i turn it off.
I've had a look around on the forums and its sounds like it could be a bios problem. i have bios version 1.1.10. i downloaded it from the dell support site, and installed as an administrator.
Any ideas what i can do now to recitfy this problem?
The desktop is out of warranty by a month so i cant claim it under warranty and have not seen anything else posted anywhere which could help me.
Thanks for any help,
Ps: Any more information you want then please dont hesitate to ask.
On your model, diagnostic lights 3 & 4 are indicating a problem with the memory. Try reseating the modules to see if that corrects the problem. If not, try the modules one at a time. Click here for an explanation of the diagnostic codes your model can produce. Click here for a reference on how to install memory from your model's on-line Service Manual.
As for the BIOS, version 1.1.11 is the latest update released by Dell for your model. You can click here for a download of it.
Thanks for the help. Computer is up and running now.
Turned out to be a faulty Dimm slot. Both memory modules work fine. Got one in Dimm1 and the other in Dimm3.
Weird fault. Wud never have guessed that without your help and those diagnostic lights.
