case fan stops spinning

am working on a presario 6000 that will not boot up. listed below are the things i have done to find the problem and i need someone to think of anything i have missed and if i havent reaffirm what i believe is wrong

when you first turn the machine on the compaq splash screen does appear but then the cursor sits in the top left of the display and stays there. also at this point the case fan stops spinning.

when i go into the bios to check the settings and reset back to defaults the case fan keeps spinning just fine but when i save bios changes and it reboots case fan stops.

tested psu with a tester and it gives a red light indicating a bad psu. replaced with a good psu and still all the above holds true nothing works.

have unplugged and removed everything except the keyboard and mouse and display and nothing. have reseded memory still nothing. i can run dos diags on the memory and h.d. and they test okay. have even used different h.d. with no results.

okay have i missed anything or does anyone have any other suggestions or thoughts as to the problem. oh, cpu fan does spin okay even though nothing else is and i get no post codes at turn on.

thanks.

 

Couple things I can think of to try, remove memory completely and see if you get any post beeps, that will let you know if it is trying to post at all. Remove and reseat the cpu or put in another one if you have a compatible one. A lot of boards I've worked with won't post if there is something wrong with the cpu or it is setup incorrectly.

had already removed the memory completely and i get no post at all - nothing. unfortunately do not have another processor to try. one thing i forgot to say is that 10 days ago we had a nasty electrical storm go through our area and the client admits the computer was forgotten about when it came to disconnecting from the wall and the phone line. have done nothing this past week other than doing insurance claims for clients because of this storm. 2 machines totally fried and others lucky just the pci modem.

have also used a post card and the readout is a 00 which the book says is a catastrophic failure of some sort. doesnt say board or processor but not good.

 

Hi,

It may be a problem with the IDE controller. If you had a PCI IDE controller, SATA controller or SCSI controller you could try those.

Try ugrading the BIOS (or flashing the same version if it is the latest), the power surge may have scrambled the BIOS information.

If you can run boot floppies etc, I think the CPU would probably be OK.

Check the BIOS is not set to "Quick POST ", it may be trying to load the wrong information for the HDD.

With all the testing you do you should get BartPE Ultimate Boot CD. I have put all my utilities on it. It has some CPU tests and benchmarks.

Check the Intel website if they might have a test system for the CPU that would run from a floppy disk or boot CD (you mentioned you could run DOS diagnostics).

okay now i'm really confused. i put this drive on my other machine and when i was trying to transfer data the profile for the user is not accessible. so i tried making the drive the master drive and my system comes up and says no drive found. so i put the drive back in owners machine and made a change from quick boot to full boot and by god the machine booted up just fine. Why???? very confused now. the case fan still stops spinning a few seconds after machine is turned on. so do i still have a bad board ??? and how about the h.d. ??? going to back up the data before i turn it off again just in case.

where is this site you mention - BartPE Ultimate Boot CD

 

You may have been lucky to boot into Windows so you are wise to backup while it is running. Quick POST just "remembers" the successful BIOS information when it was set, if there are any changes to the system it will be trying to load the old (incorrect) information about the system, like the HDD information. Doing a full POST will let the BIOS reset it's hardware information. You will probably find that if you set the Defaults in the BIOS settings it will go back to Quick Post and have the faults again. Maybe the drive's boot sector information has changed slightly from the original. After backup and if you can get it to boot up again, try running Chkdsk (error checking) and maybe run the HDD manufacturer's utilities on the drive.

If the case fan you mention is connected to the system fan header on the motherboard, replace it with a fan that connects directly to a power supply connector and if it seems to be somewhat stable with that, consider doing the same with the CPU fan. Apart from buying new fans, adapters are available for the 3 pin motherboard connector to a 4 pin power supply Molex connector, although you may have parts to make them yourself. The fan power supply system on the m/b may be on the way to burning out. I have done this on some motherboards where the fan system had burnt out and they worked fine afterwards, in fact if I find a system fan connected to the m/b I prefer changing it to reduce the power load through the m/b system.

Here is the Ultimate Boot CD download:
Windows version:
http://www.ubcd4win.com/downloads.htm
Instructions:
http://ubcd4win.com/howto.htm
This is the version I have.
(PS. Don't panic if you see the Start button change while you have the UBCD setup program running in normal Windows. I thought it may have been due to a virus originally. If you want the Windows Start button, right-click and select Exit.)

This looks like a DOS based version:

I think I will get that as well, it has a lot of the HDD manufacturer's utilities.

yep, already backed up her data over 8g worth. ran both manufacturer h.d. diags and pc certifies and all pass as well as chkdsk /f. no problems found.

i agree with the case fan part. i also would rather it be connected to a power plug from the psu. unfortunately i only have 80mm and it dont fit so need to search for one or make a trip to compusa or the like. i think its a 120mm.

right now am unable to get the network adapter to install itself even after running compaq drivers for it including the chipset the **** adapter just wont come back. going to just disable the onboard and install a pci card.

also upon running spyware doctor it found 1178 bugs one of the worse ive ever seen and she has no virus protection. some people and the way they treat their machines. unbelievable.
