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.

    First thing first is talk to Dell and see if you’re still eligible for any form of warranty support.

    Also, if you purchased the computer with a credit card, you may be entitled to an extended warranty if dell doesn’t cover you. Contact the credit card customer service number on the back of the card used for the purchase for more information.

    All that said, your problems are likely related to overheating. See these pages for details: http://arstechnica.com/civis/viewtopic.php?f=7&t=232439

    Anything you can do to get more air moving over hot components that aren’t being properly cooled will help, try a big box fan.
