I have a Deskpro EN with a standard Compaq 32x CDROM installed running W98SE. I wanted to add a CDRW. Expecting to find inside an IDE cable with two connectors, one connected to the existing drive and a spare. Oh no. A single connector cable from the CDROM to the 2nd IDE channel. The hard drive...

I almost forgot - this computer came with a single 256 mb RAM card in, DIMM, 133mhz etc. According to Crucial.com it should only have up to three 128 mb cards. It seems fine. Can I safely add a second one of these, 256 mb again. (I have a 64mb card in a drawer as salvage, but it is different...

Dear group, I am trying to upgrade a friend of mine's computer from a Pentium II 266 MHz Slot-1 to a Pentium III 450 MHz slot-1 processor. I have a processor that works, and have already run into the SDRAMs only being PC66 DIMMs, rather than PC100 for the 100 MHz FSB. However, I don't know what...

Working on one of these old boxes, setting it up for home use, came across this weird problem. If I leave the power cord in, even with everything else disconnected, the machine still manages to boot itself up more or less 15 minutes after shutdown. I'm guessing PSU or motherboard issue? Maybe...

I have a Compaq Desktop model Deskpro EN that I hardly ever use. It sits running. I only have one visual basic billing program that I periodically use. This morning I went to boot it and got an error message that the file windows 2000 root\system32\ntoskrnl.exe was corrupted and needed to be...

I have just bought two EN P-550's. They work fine but I need to install a wireless lan card in them. I am trying to use a new belkin 54g card. The BIOS does not list the wireless card and neither W2K nor XP lists the card. It's not a driver issue. It's as if I simply have not installed the...

Hi, I work for a non profit association and we were given two Compaq PC's by a company: one PIII 450MHz Deskpro, and one PIII 866MHz Deskpro EN (with no documentation nor software on floppy/CD ROM). I have no idea of what is installed on their disks. Both PC refuse to boot from the hard drive...

Hi, I got this small,old but fine maschine. In the default configuratoin it works fine, but when I insert a PCI-card in the extension-slot I get a system crash. Now I would like to try a BIOS-Update, but I could not find my system on the compaq/hp website So how could I get the right ROMPaq ? I...

I bought a deskpro P3 733mhz with 16mb onboard agp graphics 128mb ram. I am running xp pro on it but the graphics stutter. Thinking that the onboard vga was not up to the job I installed a TNT2 M64 16mb PCI card but get the same thing. If you run dxdiag it shows the bouncing square stuttering...

Hi, I'm having a problem with a P800 Deskpro EN. It randomly powers off and won't power on again until the mains lead has been removed for a time. What I notice is that when it shuts off the C32 AUX 5 VCD LED on the systemboard lights up. It is usually off while the system is running. Can anyone...

I am trying to build a Linux mailserver out of one of these machines but at a cold boot I get a message that the machine has noted the two drives and I must hit F1 to save these. I do so and the screen goes black and a moment later the lilo boot takes off just fine. I have gone into setup (F10)...

Hi, I've been using a fairly old Compaq Deskpro EN (the convertible tower/desktop model, with a Celeron 400 CPU) as a file server on my home network. Chose it because its fan is nice and quiet and the machine *seemed* fairly indestructible. However, last sunday, after running it non-stop for four...
