I've been repairing some boards here and there. Mostly scrapping anything under 1.0 GHz now. Good money in e-scrap. Been working on those Dell SX also. What a piece! Still doing Optiplex/IBM SFF PSUs
Anyways this Compaq is not much different from the crap Dell makes. Presario 6000CL w/XP Home SP2. MB is a A7V8X-LA w/o the latest Compaq BIOS upgrade installed. The XP2800 proc is gone for an Athlon 1400. Memory is 768MB DDR266 tested with Memtest. WD 180GB PATA tests Good with Spinrite and DFT. Fairly new PSU is questionable- Austin 300W ATX showing rated for 280W/180W 12V/5V 3.3V. This is how I got it handed to me.
The board is populated with TEAPO instead of the usual OST/Elite/United -Chemi. There's only three caps that are United-Chemi 1200uF 16V. When machine appears to be under load (booting/downloading updates from web for example) a high pitched ringing or oscillation emanates from the board in or around the backplane behind the I/O header. While booting, if the blue dotted line in the XP splash is scrolling it will stop quick every time this sporadic noise is heard then continue. The machine will boot up to a desktop and be fine for about 5 min. or so and then it will just freeze requiring a reset. It will freeze just idling with anitvirus and software firewall running in systray and thats it. If I download something from the web it may or may not freeze part way through. Just wanted to know your thoughts on this one. Should I bother to recap this one? It has a lot of headers for USB/1394/SATA. I'm using the onboard video and have swapped the PSU with a known good Antec. The PSU mad no difference.
Thanks in advance
P.S. Is there anyway to search a particular board or machine model or brand in this forum once you reach the desired section? It would make it easier to see if someone else has a similar issue with the same component/brand/model.
