compaq ex – user’s pc had been running for about 3 hours and then:
STOP: 0x0000007b (0xf901b84c, 0x0000034, 0x00000000, 0x00000000) Check for viruses on your computer. Remove any newloy installed hard drives or hard drive controllers. Check your hard drive to make sure it is properly configured and terminated. Run CHKDSK /F to check for hard drive corruption, and then restart your computer.

Did what the instructions recommended. Tried two different HDs. NO JOY!!! HELP!!!
Thanks. Have a great day. God bless. Regards, Lupe
