Ok I'll start from the start here on the problem I'm having with my PC.
In March I purchased a 128Mb Nvidia FX 5200 MSI graphics card. It was put into my pre existing computer with the following specs:
Jetway N2PA-ultra Motherboard (NForce 2 nVidia chipset)
AMD XP 2000+ CPU
The above graphics card
512Mb of RAM (2 x 256Mb PC2100 DDR) running in dual channel mode
52x ATA CD ROM
40GB 7200rpm ATA100 Seagate HDD
40x12x48 ATA CD-R/CD-RW/CD
A:/
V92 PCI Internal modem (Netcomm)
Intel 10/100 PCI Network Interface Card
Approximately 2 weeks ago I decided to upgrade my CPU, RAM and HDD to the following:
AMD XP 2800+ CPU (Barton Core)
1024Mb RAM (2x 512Mb PC3200 DDR) still running in dual channel mode.
120GB 7200rpm 8Mb Cache ATA133 Western Digital HDD
New casing and 400 Watt power supply.
I've never overclocked anything in my PC. What did happen was that I left the 40gig HDD in my PC along with the new 120gig, I was doing the upgrade so that I could give my old CPU and HDD to my son, so the 40gig HDD was removed, up until then the graphics card didn't have a problem working.
Sounds easy right?, remove the 40gig HDD, change the settings in the BIOS and move a jumper so that the 120gig was now the master. Reinstall windows XP because it wasn't on the primary drive before, download all the windows updates, put all the drivers back on. The jobs done.
Now we come to turning the computer on. No picture (monitor stays in standby mode, never receives a signal), computers internal speaker doesn't even beep, and the computer is constantly restarting itself (the only indication of this being hearing the CD-ROM spin up then spin down again straight away, repeatedly.) ... Houston we have a problem.
Troubleshooting time, the RAM was taken out and checked in my sons computer, it's fine (whew!). Checked all the connections, the gfx card was in the AGP slot nice and snuggly. Tried pulling out all the expansion cards (network card and modem), disconnected the HDD and CD burner. Every time we plugged the sucker back in, no picture and it kept trying to restart itself.
Ok time to start thinking outside the square, so the gfx card was removed and replaced with my sons 128mb ECS ATI Radeon 9200se, plugged the computer in and it booted and we had a picture so then we double checked the CMOS settings, settings were fine, so that wasn't the problem.
We seem to have eliminated the crashing and over heating problems that it was having by putting in a new power supply (the older one was very dodgy for some reason) and flashing the BIOS.
Fingers crossed we've now fixed the problems, so we tried putting the FX 5200... *screams* ... it does the same old thing, no picture and keeps trying to restart itself. So I have the Radeon back in my PC and the computer hasn't crashed, so for now it looks like it's staying until I find the problem.
I want my FX5200 back!!! It has worked in this computer before and is working in every other computer in this house (3 of them), I want it to work in mine again. I have had two computer technicians working on this problem and they are both at their wits end trying to work out what the glitch could be.
It may be something small that we have completely overlooked and is plain as the noses on our faces, so any input would be appreciated.
HELP.... please, for the sake of my sanity. Ooops too late!
