The one really rattles the brain.
The computer was "slow", which is why I was called out in the first place.
The first thing I noticed was that it took literally 3-4 minutes to turn on. This is a fairly fast, low cost computer I built for a company about a year back with the following specs:
BIOSTAR A880G+ Motherboard
3.00 Ghz AMD Phenom II X4 960T
Windows 7 Ultimate
Seagate ST3500413AS 500GB 6.0Gbps HD
4GB of Memory
It was getting stuck on the BIOS screen (everything about the BIOS seemed slow, I could read the information quite easily as it flashed across the black screen and it took a good 30 seconds for anything to even show up) around loading the hard drive, so I switched the hard drive SATA cable and also the motherboard's port.
Now the BIOS loads up as fast as you would expect it to, but the OS is still excrutiatingly slow.
I manage to get to the Windows 7 "Install" screen after about 10 minutes of waiting, when I had just tested the exact same install sequence on a much slower laptop earlier that day and it took all of a few seconds to hit the "Install" screen.
Could the motherboard be "broken" but still working, perhaps?
I just checked the hard drive using CHKDSK and SeaTools and it passed with flying colours. There was some mention of "Bad LBA: ### Not Repaired" inside the SeaTools analysis but that's about it.
The only other thing I can think to check would be to swap out the memory..? But Belarc advisor claims it can find all of the Memory and that it's working properly.
