Possible defective motherboard?
Posted on 2005-04-29
HP Pavilion 7950
First got this machine in March. Had been in a home that survived both hurricanes last year. (Jensen Beach, FL)
While servicing another machine, customer asked me to check this one, had boot failure and not used since they returned to home last Nov.
PC booted to a steady beep, no video.
Showed no physical damage, i.e. water, etc.
Removed all boards, memory, etc. and cleaned.
PC now booted, ran good, steady 48 hours. Ran #1 Tuff Test Pro, HD and mem OK.
Upgraded mem to 512, upgraded from ME to XP.
Had running for another 48 with no problem.
Returned to customer. Had it one day and boot problem came back.
One short beep, than steady long. Blue "HP Invent" boot screen comes up but won't go any further.
Redid all boards, PCI, Mem, DA, Same.
Replaced mem and display adapter, same.
Customer has $ invested, through me. (Upgrades based on my recommedation.)
Would like verification or any other tips before I replace mobo.
