Why does my computer lock up when I am gaming? 

by on October 5, 2011

Q: Computer lock-up: I have a Dell Optiplex GX620, 2gig ram, Sabrent 5.1 3d sound card (onboard sound shut off), Hitachii 500gig HD, BFG 210 512mb PCI-e video card, flat screen monitor, Pentium 4 3.0 CPU. Using the internet is no problem, gaming is. About four months ago my computer started locking up with chatter sound and “no input signal” on the monitor. Could someone tell me if this is a motherboard problem, or is it a problem with something else? When this occurs I check the cpu cooling fins and they are only warm to the touch. I will be greatful for any help, I have no computer repair skills and no money to take my computer in for repairs. Thank you, Ray.

Heat sinks or no heat sinks

Q: Is it bad to put heat sinks on any if not all the motherboard chips?

A: You will want to figure out if adding heat sinks to your motherboard will void the warranty. Adding them might also cause issues if you have to RMA the new motherboard, especially if you’re using any kind of permanent or semi-permanent thermal adhesive. Since heat sinks are metal you’ll need to also be very careful to avoid causing any kinds of shorts which could potentially toast your new motherboard. Read the rest of this entry »

Steps To Take When Windows XP Keeps Freezing 

by on February 26, 2008

Q: I have a Dell XPS 400 desktop and recently it has started to freezes up for no apparent reason. It is running Windows XP and I have tried everything I could think off including reinstalling windows, but again it froze up during installation. I would really like some help.

A: The first thing I would recommend is to run an anti-virus software program like AVG to make sure that your machine has not been infected. If you are virus free, then I would suggest downloading an anti-spyware program like Ad-Aware. If that is not the problem then the next step would be downloading and installing a free program, called HijackThis.

Unfortunately if none of these solve the problem, and they might not due to the fact that your computer froze during reinstall, then the problem might be related to your hardware in the computer. Maybe the CPU fan is not working anymore causing the computer to over heat and freeze up. Maybe the video card fan is not working anymore causing the computer to over heat and freeze up. So you will want to check all the fans in the system and maybe even try running your computer with the cover off and see if that helps a little bit.

Getting in your computer with a vacuum might even help to get the dust out that seems to always built up inside of a computer causing air to not travel as easily.
