I am having a problem with a computer that I just repaired. The original problem was the power supply for PC didn’t turn on after electric storm. I replaced power supply for HP Pavillion a1510n an this is what happened:
1. Replaced power supply.
2. Turned PC on got error: logonui.exe instructions at ?0x005f0675? referenced memory could not be written.
3. Ran PC-Doctor, Basic test , short test failed; Error HD521-2w. It seems Hard drive is failing. Optical drive and RAM good.
4. Ran PC recovery and PC was able to boot up normally. Tested for few hours, removed Norton & Installed Avast, Did full antivirus scan at boot up ok.
5. Next day turn on and get the following:
Award Bootblock Bios v1.0
