is there any recommended programmes to detect and fix errors on the computer?

Iwas looking at something like first aid, but wondered if it would help me.

I currently get lots of screen freezes & error messages inc:

KERNEL_STACK_INPAGE_ERROR,
DRIVER_IRQL_NOT_LESS_OE_EQUAL
and 'disable BIOS memory option such as caching or shadowing.

I have a giga-byte ga7va rev x1 MOTHERBOARD which i updated the driver on a couple of days ago, which seems to have made it much, much worse.  When i try to revert to last good settings nothing changes.

There is a exclamation sound on startup as well.

phew! alot to go through, please help!You can get an EXPLANATION at:

The driver update is the most likely cause. Rolling back the driver MAY be a good option.

Good luck.  create a BART cd on a buddy's pc (Bootable Antivirus Recovery and Troubleshooting cd) then boot the pc with the cd in the tray, goto the system restore options and select a date when everything was ok. Get System Mechanic 5 trial software here: http://www.iolo.com/sm/index.cfm and run it once you get up and going Cheers.where can you roll back the driver for the motherboard???

not LISTED in devices?

confused!
