So a guy at work brings me a computer that will not do anything.  I opened it up and it was filthy inside and had 9 blown capacitors. It was a HP Pavillion desktop running Vista.  I decided the best route was to buy a used motherboard on ebay and switch it out.  The motherboard was a MCP61-HM.  Got the board and switched everything around and fired it up....first thing I noticed was when I plugged in the power cord, all the fans came on and running at full blast.  When I pushed the power button, everything settled down and the machine fired up.  After removing 22 toolbars and cleaning up 2500 or so infected files the machine was running good.  I used it for about 2 weeks and then got it ready to take back it's owner.  Unfortunately, he was fired and I've never seen him or heard from him again.  Pulled the machine out of the closet tonight and tried to fire it up.  It tries to let me chose between safe mode and the like but will not seem to boot.  Goes into a loop.  I can see a BSCOD just before it clicks and tries to boot again.  I can get into the bios, but nothing seems to help.  I put in a hard drive that I know works with the same results.  I still get the crazy fans when i hook up the power cord, but when I push the power button it settles down.  Not sure where to go now.....any suggestions would be greatly appreciated.

For a spare computer I would get rid of Vista and install Linux Mint Cinnamon 64bit. Now your chances of getting infected are slim and none.

Can you boot a CD/DVD disk or USB flash drive?  The linux install boot disk will completely bypass the BSOD if it isn't a hardware problem.

Well I got it to boot.  Took all of the connectors lose and reconnected.  This particular computer had built in video and so I decided to drop in a video card I had lying around.  Fired it up and it went to a screen telling me of errors and such.  Never have seen this particular black screen before.  Wish I had written down what it was saying and asking of me.  Made a couple of choices and the computer booted right up!  Must have been something wrong with the onboard video.  Talk about luck!  I'll take it.....

Glad you got it to boot and thanks for the feedback. Just for the heck of it take a look at Mint. Vista extended support with security updates ends in April 2017 and it's a pretty crappy OS too.

I neglected to say that after I worked on the computer I installed Windows 7 Pro.  Got nothing running Vista.  I did download the Linux Mint and burned a copy of it.  Going to check it out.  Thanks for the links.

Those fans still raise hell when I plug the machine in and then settle down and run fine once I press the power button.  If the machine goes into a hibernation mode, it will not wake back up.  I have to then unplug the power cord, plug it back up (racing fans again) and press the power button again and it resumes windows right where I left it before it went to sleep.  Any ideas on that one?

I am not sure. I had a emachines that would not get out of sleep mode and when I installed a new PSU, the problem went away. Racing Fans would seem to indicate a heat issue. You can check out your temperatures with Speedfan. Has the Desktop ever been opened up and dusted out?

When I got the machine, it was so filthy and had gotten so hot that it popped about nine capacitors on the board.  Bought a used board from ebay, cleaned everything to about new state and put it all back together.  Quick recap of the first post.

I would check your temps with SpeedFan. If the temps are okay then it may be a sensor on the motherboard that is throwing off the fan speeds.

 

If you go into BIOS is there a setting for fan speeds and temperature? You first post lists the motherboard. The specs shows it uses an AMD processor. In the BIOS look for something called "Cool and Quiet". I am not sure if this motherboard has it though. It will automatically adjust fan speeds based on temps.

i had that RPM problem with a computer once; turned out that it was the video card fan running hyper-speed. Deleted and reinstalled the card drivers and reseated the fan and the problem disappeared. I also suggest resetting the CMOS back to factory default. As far as the power button issue...make sure you have turned off all screensavers and sleep modes for the computer. Just for a test, power down, pull the lead from the power switch where it plugs into the mainboard and cross the two tiny contacts with a screwdriver. Does the unit power up properly without the hibernation problem? If so, you have a power switch on the way to failing.
