I'm working on an IBM NetVista 8315KHU , WinXP, New 256 DDR SDRAM, New 80mmCaseFan , other parts are as per original specs.
Orig. problem began as an "out of blue" worked fine til bedtime, tomorrow after work - no boot.
No household power issues or anything weird.
Opened, cleaned, examined - only obvious was case fan had fallen off wall of case, rubber screws(2 of 4) had aged and broken, other 2 held it on. It had a single 3-pin, 3 wire tiny connector to mobo at uninstall.
Purchased at Radio shack a new 80mm, but this one had a "single wire" tiny connector (that I attached to mobo)...and two spare molex 4-pin (one male, one female)...I attached the male to a spare molex off power supply marked code P2. Looked up connector diagram and made sure that yellow - yellow, red-red, black-black were in order.
Tried boot again.
Nothing. IBM bios screen, then Windows black logon screen then all black monitor. No DOS printed matter of any kind, no alerts, warnings, or messages.
Researched multiple forums (incl.Daniweb), and suggestions were made that original issue may have been faulty memory.
This IBM had had only one stick (128mb) - I filled both open sockets w/ 2 entirely new 128's (per machine /make/model). He had always commented that it seemed slow, so that didn't seem entirely outta the question.
I am beginning to think I'm in over my head, when I work on a machine and get too worried or scared or confused to find the correct connections, troubleshooting, etc. and I am working on this machine for my husband - while he's on "borrowed time" using the older teen daughter's for the broken moment. It's a time-element until she gets too bust waiting for me to fix his, and takes hers back upstairs.
This machine has had regular care and maintenance, and is single-owner (us). I am three yrs. into self-taught and have worked on about 65 machines - but mainly virus removals, and upgrading hard drives, OS installs, cleanings, etc. as well as learning each time.
Electrical and peripherals are still in my learning curve., but scare me because I have a pacemaker in me besides electric needing adequate cautions. I have a sturdy understanding of PC's - but have MUCH to still learn. I follow the most commonly advised troubleshooting methods - from mobo/power /input tests without any other hardware attached, to the read everything I can "before" I go "in" to find out the "why"....going by symptoms Googled.
Can anyone assist with any new suggestions I can try, before I touch, mis-wire or forget something and toast his whole PC out of commission ??
