For the past few days i've been getting trouble with my pc.
Sometimes i'll turn it on & it won't boot up & i'll need to go into the BIOS & change all the settings.
It seems everytime i turn the pc off at the main socket, it forgets all the settings in the BIOS & i need to set them again before it boots up.
I think its a CMOS battery issue, but that's not the main problem just now.
Well, yesterday when i turned the computer on it said the power connector wasn't connected to the GFX card (even though it was) & obviously refused to boot up.
Sometimes a simple press of the reset button sorts this & other times i need to fiddle about with the power connector to the card & even plug in the other connector instead.
Eventually the pc booted up to desktop & everything seemed fine & then i got a BSOD.
It said something about Bad Pool Caller or something.
I got a BSOD not long before this as well that said something like IRQ Less Or Equal.
I ended up getting it to boot up & was on the pc for a few hours last night & shut it down from the computer & left it until today...
When i turned on the pc today i got the usual message about the power connector not being plugged into the card, so i stripped the pc out & cleaned it all out & it eventually let me into the BIOS to change the settings & it booted up.
This time with a major difference.
The screen resolution was reset to 800x600 & in device manager there were 2 errors.
There was a yellow exclamation mark next to the GFX card & also one next to an SCSI & RAID Controller.
When i double click the one next to the GFX card it says:-
This device cannot start. (Code 10)
When i double click the one next to the SCSI & RAID Controller it says:-
Windows cannot load the device driver for this hardware.
The driver may be corrupted or missing. (Code 39)
Does anyone have any idea whats up or what i should try ?
I'm seriously getting sick of this PC lark..
First thing I'd swap would be the power supply. Low voltage on the 12V rail could cause your symptoms.
Be aware that if the video car has a power problem it could be sucking down everything else. Be prepared to have a spare on hand (you can get a cheap one for troubleshooting purposes. Buy off eBay or at a store that takes "No questions asked" returns.
Another thing to keep in mind is how many other appliances are using the same power point & being on at the same time,if it's just the comp & monitor then yep power supply like dailun said however there are some things you can try,if you have dual hdd's & the graphic card uses the same plug on that line,switch it for the dvd player instead,strange i know however it worked for me on one of mine,check plug ends are not loose you may have to recrimp use a pair on needle nose pliers or a strong set of tweezers or a small screw driver (the plug ends i mean are the same as the ide hdd power connector)

Still playing Black Hawk Down why did I upgrade?
Well, i use a 4 plug adaptor & the only think on it barring the PC, is the speakers plug.
I'll need to check the wiring, but i think on one line there's 2 moles power connectors & one for the graphics card & i link these upto 2 hard drives & obvious;y the GFX card.
On the other line there is a molex power & GFX connector along with a sata connector & these connect to my sata drive, dvd burner & the other connector for the GFX card doesn't get used.
As for swapping the power supply i think that's a last resort as i'm going to build a new up to date system in the next few weeks & this PC will just go to the gf.
But i checked the 12v rail & it says 16A.
dougal79 - I would see if it works OK with the onboard video. No...that isn't true; I would pull the capacitors and the more expensive connectors for my parts bins, and then toss the POS into the garbage...but my GF already has a very nice laptop.
