From: Don Phillipson on 20 Feb 2010 15:20 On Compaq Presario 7000CA (WinXP) the old CRT monitor Philips 201B10?7414 (2001) failed recently, going black after an hour or two in use. After switching off and on again, a distinct double click was heard, screen remained dark. Next day it performed OK. So I swapped it for an old Dell MM781S CRT monitor (2000) believed good because when powered up (with no PC) it shows "No signal, connect computer.") When connected you get (1) tiny green spot in mid-screen for 2 seconds, then black, (2) on/off lamp next to on/off button blinks steadily (green.) Does this indicate a dud or dead video adapter? It is believed to be NVidia GeForce2 type. Should I test something else? Is this (antique) video card easily replaceable? -- Don Phillipson Carlsbad Springs (Ottawa, Canada)

Just to double check I would take the Dell monitor to another computer and hook it up to verify that the card has actually died. As far as replacement of the card, that should not be difficult. Most likely you have an AGP video card installed rather than a slower PCI video card, from me looking at your model and checking that it had an AGP slot. Do check first, by opening the case and verifying that the vga card is AGP rather than in a PCI slot. Changing cards is relatively easy. To find an AGP replacement check out an online store, ie, newegg.com or wherever you purchase your hardware. Jan Alter bearpuf(a)verizon.net

After reseating the card and flushing BIOS I got one OK boot into Safe Mode, reinstalled nVidia card, which requires reboot to implement -- and this time hung at driver\mup.sys see http://www.aitechsolutions.net/mupdotsysXPhang.html suggesting hardware (video card or PSU.) There is a hint here that AGP cards draw more power than others. Another clue is that the floppy drive also recently failed -- perhaps also pointing to the PSU. While the case was open I added an old spare floppy (not marked good or bad) -- and then found its data pins were not pin-compatible with the Compaq data cable (and my spare data cable did not fit the Compaq MB.) Was this a brand peculiarity of Compaqs a decade ago? -- Don Phillipson Carlsbad Springs (Ottawa, Canada)

I would be as suspicious as yourself and would be thoughtful to replace it on simple insurance at this point with two peripherals failing, Check out that your machine is using a standard ATX power supply and not something Compaq prioritzed. No doubt your mb will have a 20 in power connector. And if it is using a standard PS make sure that any replacement will have a 20+4 pin mb power cable and just not a 24 pin one. As for a priority floppy drive, that's a new one on me. But from my experience with Compaq's I'm used to them using priority screws to fasten their CD-ROM drives to the chasis. They used to be a royal PITA. Jan Alter bearpuf(a)verizon.net

This Presario fastens all floppy and CD drives with rails that snap directly into the screw holes in the cases, yet hold securely. The two HDDs are mounted (vertically) with one or two screws each, inside a 2-drive cage that fits tight and solid. Eccentricity was reserved for the bulbous snap-on case front (with trim ring in a variety of colours . . . ) -- Don Phillipson Carlsbad Springs (Ottawa, Canada) |
