I got a call today about a pc running slow. They also said it would sometimes make a noise like the fan was broken or something was caught in it. So I spent an hour and a half deleting junk & temporary files, scanning for malware, configuring start-up, and removing unnecessary programs. Then I took the tower outside and used compressed air to blow out all of the dust, trying to get rid of the fan noise. The unit was extremely dirty...lots and lots of dust.

So, when I plugged the pc back in and turned on the power, nothing comes up on the monitor and the pc starts making a constant beeping noise. The monitor turns on fine and says "no signal". Both fans run fine...no more buzzing sound. I've tried everything I can think of and this is their main computer for the business. I have to get it back to them ASAP.

I've tried switching out the sticks of RAM. I've removed all of the dust as best I can. I've tried unplugging all of the drives...cd rom, floppy, and hard drive and plugged them in one by one. I've tried different cables, a different monitor, a different keyboard and mouse.

This is a Northgate desktop PC. The MB is a Gigabyte RZ series. No video card...uses an integrated GPU. Any ideas what this could be?

Have you tried reseating the Heatsink (reapplying TIM first of course) and the CMOS battery?

What was the source of the compressed air. Anything more then canned air may have been far to much pressure.

Also since you moved it around and blew it out make sure the RAM, expansion cards and various cables are seated securely as well.
Get your facts first, then you can distort them as you please.

I figured it out...kind of dumb on my part but a learning experience. I've installed hundreds of sticks of RAM and this was a first...

I took the RAM out while I was dusting and noticed I had some difficulty putting it back in. But, I was able to seat it with the end clamps down in position. During the entire troubleshooting process, I probably pulled the RAM out a dozen times or more and put it back in. It wasn't until I pulled the MB out for the 2nd time that I realized the connection plates on the memory stick were showing. The MB was bowed-out, and even though the clamps were shut tight on the ends, the RAM was not seated all the way across.



Thanks for the input.
