Hi all, I'm new here and am hoping someone can help me with my problem. My wife's computer has been suffering repeated BSOD the last couple days (although she tells me it's been happening occasionally for several months). The first error said that the "nv4_disp" file was stuck in an infinite loop. I did a little research, and tried to uninstall/reinstall the nVIDIA drivers/software. I couldn't get that to work right, so I used the system restore utility from the command line in Safe Mode, and that seemed to do the job (at least it would boot to the Windows login screen). The computer started fine this morning, but when I tried to install a new version of Norton Internet Sec., it wouldn't restart. The fan will run on high (like it usually does when booting), but it won't even post. Then it usually will post and boot on the next press of the power button. Repeated reboots on the power button results in repeats of this sequence. Occasionally it will boot to Windows, but then the display is scrambled. Finally, the last time I tried to start it (a couple hours ago) I got a "machine_check_exception" error with the following STOP codes: STOP: 0x0000009c (0x00000004, 0x80546e70, 0xb2000000, 0x00070f0f) This machine has always had trouble with standby/shutting down. It will often hang at high fan speed (like it usually does when powering on/off). The computer is an eMachine T6216: XP Home Athlon 3200 4GB RAM 160 GB HD onboard vid (nVIDIA GeForce 6150LE) onboard sound I'm suspecting it's a video hardware problem. And I'm wondering if throwing in a cheapo vid card (and disabling the onboard) might fix the problem. It's only used mainly for e-mail, Web browsing, word processing, and the like. Nothing heavy duty for proc or video. I don't feel like investing in a new mobo (if that's the case, I might just pop for a new computer--the monitor is new and works fine). Any suggestions would be much appreciated.
