Whoops

[Newt]

Hello all.

Here I am again requesting help. I recently decided that the family PC wasn't up to standards and tried to install a radeon 4870.
Being that I rushed the job I forgot to check if the PSU had the right connectors and low and behold it didn't.
Now here is where the problem lies, upon rebooting the PC the wireless network card decided to give up.
I went into device manager and saw it there for a few seconds before it managed to disappear.
After readings tips I powered down the computer and unplugged the wifi card and put it back in (Classic fix) this didn't work.
After having no internet I got a little desperate and did a system restore. I came up to check on the PC after about an hour at which the screen was blank.
I left it another hour and restarted it.
Now the monitor wasn't being detected.
So I opened it up again and removed the CMOS battery. The monitor is now being detected again but I’m not sure if this is just luck.
It is now up and running again with and getting the internet through a usb dongle.

I didn't take my usual precautions e.g. anti static wristband, but I can't imagine I fried the wifi card especially as I didn’t touch it the first time.

Any help on anything in the above would be greatly appreciated either to help fix my PC (getting the wifi card working) or to just expand my knowledge.

The 'classic fix' usually involves removing the device in hardware manager, powering down, removing the device, rebooting, powering down, replacing the device, and then re-installing the drivers etc. In effect doing a full re-install of the device.

Unfortunately that doesn't always result in the removal of the drivers so problems can persist.

But if you didn't to that procedure (as I described), it might be worth trying.

Have you tried the wi-fi card in another machine?

I take it you haven't left the 4870 in the computer while you're doing all of this?

In fact, we could probably do with a bit more info on what you did in terms of installing the 4870 - did you just turn off the PC, stick it in, realise you didn't have the right power connectors and take it straight out again, or did you try to power on the PC with the 4870 in it?

Sorry for being a little vague
What i did was power down the PC put the into the slot (after moving a sata cable or two out the way) then looking for the 6 pin connecters or enough spare molexs i saw there wasn't enough so before powering up the PC i removed the card and left everything as it was.

I'm not too bothered about the wifi at the moment but my main problem is that that monitor is not detecting the computer. The motherboard uses an integrated gpu so i can't understand why. I thought i fixed the problem last night by removing the cmos battery. It worked again this morning but this evening the monitor wasn't detected again. I then removed the battery again to no avail so tied taking out the ram as well, for some reason that worked.

As I’m leaving in a couple of days i don't want to leave it semi functional. please help :s

Could be that you disturbed something while installing the GPU, resetting the bios parameters may have been a fluke (you did disconnect the computer completely from any mains supply while you were clearing the CMOS?)

Otherwise back to basic faultfinding, strip the PC down and the rebuild, testing it each time you add a component.

... What i did was power down the PC put the into the slot ...

OK, slightly basic question so please don't take offence, but: Did you unplug the power cable from the PSU whilst doing this?

Ha don't worry no offense taken. Yes I always unplug everything from the pc before sticking my hands in there
