Yeah, I just visited the shop and the card didn't work on another machine either. We concluded it was a used card with a ****ty repair done to it.
I ordered a new ATI 5770 (with 50% price reduction). Let's hope it works. (EDIT: luckily I talked to the boss of the shop and he decided it was partly their fault and now offered me the card
for free!
)
And now my PC won't boot with the X600 in. I toggled safemode with networking and it just gives a blank screen (worked okay with normal Windows boot before toggling safemode).
Then I rebooted but the computer beeps with a chaotic sequence I can't really make anything out of (could be long-short-long or long-short-short or short-short-short or anything similar). Then it rebooted by itself and some fan got some god damn high speeds which I've never heard before. I need to check my BIOS post code when it beeps.
I sincerely hope the card didn't **** up anything else in the system. I did get some MOM.Implementation errors, but they relate to ATI drivers which I removed before popping in the nVidia card. I haven't yet got to cleaning the driver installs, was on my list next.
EDIT
Well now it booted, something random happened first. The ultimate fan speed is because my BIOS was reset. On boot up my it said checksum was wrong and reset itself... Now I need to redo all my BIOS settings. Gladly the computer now just works and I can even browse the web and play UT1.
The MOM.Implementation errors didn't go away (also get a CLI.Implementation error when trying to launch CCC) after re-installing the ATI drivers. Though I read that Driver Sweeper sometimes removes a bit too much. People told to install .NET 1.1 to get the problem fixed or something. I might try it later this evening.
I'll return if problems continue. Off to set BIOS settings. ->
EDIT2
Oh and Dropbox.com and Gmail are bitching about "insecure connections", could this relate to a BIOS reset? (EDIT: yeah, my BIOS reset the date and time, which was quite wrong and the connection timestamps didn't recognize it.)
