Computer lock up

[Gokauka]

Ok so I've had an asus for awhile, haven't added anything to it, but my computer keeps locking up. Video card driver issue or could it be something else?

Edit: It's an NVIDIA GeForce GT 220 I just updated the driver today.

Computer locking up is not the best thing to say when trying for help. Was it blue screened? Just stops responding? Are there error codes? What makes you think its your video card? etc, etc.

Just stops responding, and SOMETIMES not always I will get a blue screen

Still need advice

Locking up could be anything, PSU, RAM, GFX, Overclock

Use a program such as speedfan to keep an eye on your PSU tensions (check temps while you're at it) while gaming.

Remove some RAM, try with only one DIMM at a time. And then memtest them. (ultimatebootcd.com)

Get back to clock speeds if you're o/c'd

Use something like hwmonitor to see if you're overheating also. Check for spyware/virus

If possible post the error information you get on the blue screen. BTW did this problem just start happening when you updated the driver or was it an issue before?
