About a year someone gave me an older HP machine that was shipped with Vista and then upgraded to Win7. The owner upgraded and said take the tower, wipe the drive, and have fun. I ran it for 6 months or more with Ubuntu then reinstalled Win7 and sold it to a friend. He used it for three months without a problem and then all of the sudden it started freezing up, crashing, black screening, and I even got a BSOD a couple of times. Tested the memory (4 Gb) and HD (500gb WD Black) and all is good with those parts. It has an upgraded power supply (Antec Neo-Eco Green 430) too. All fans are working as expected (low and high speed work depending on load. It is running the on-board nVidia 430 video too. AMD Phenom 9150e processor IIRC.
I am totally stumped on this one. Here is what I have ruled out so far but might be missing something:
- RAM tests good (let run for 12 hours of MemTest thru bios)
- HD checks ok using SMART info
- case is clean and all fans work as expected
Do you have any suggestions for this one????
