Hi all,

Around 9 times out of 10 when I boot up my computer the monitor doesn't show anything, but the computer itself boots (I hear the Windows chime, etc).

But when it does boot up, it works completely fine - even for a whole day.

Then when I shut it down and restart it will just not work. Is the PSU is not powerful enough?

Computer specs:

AMD Athlon 64 6000+ AM2 Processor Retail Dual Core AM2
Gigabyte GA-MA78GM-S2H AMD780G 5200HT DDR2 VGA PCIE2.0 RAID GbLAN 1394a
DDR2 2048MB(2G Single stick)PC6400 800Mhz (I have two these, totalling 4 gig)
Samsung 250G 7200RPM SATAII
NVIDIA Geforce 8800GT 512 meg
Liteon 20x DVD Dual Layer DVD+/-Rburner Black Retail (DH-20A4P)
CoolerMaster Centurion RC330 Elite Black with 420W + HD Audio(RC330KKRA)

Some extra details:

- I have tried plugging/replugging all cables in, so it's not the cables or anything obvious like that.

- I use an NVIDIA Geforce 8800GT 512 meg card

- The onboard video works every time, if I switch from the Geforce card to the onboard video

- I have had one or two 3D game crashes the last month (in GTA IV), but not enough to warrant suspicion I don't think.

- The computer was frequently beeping at me, with a few freezes here and there, until I cleaned out all the dust last week.

Welcome to the forums!

Check the operating temperature of your video card with GPU-Z.
There are some firmware updates to deal with temperature problems.
Your power supply has enough power.

Hi there,

thanks heaps for your reply. I have downloaded GPU-Z and ran it for a while. Here is a screenshot of my results. What do you make of it? I am also downloading the latest firmware. Thanks again for your help :)

That card is running quite cool, is it loaded or just idling in desktop??

Have you checked if the card is seated properly in the PCI-e slot??

Exactly. Based on the symptoms of your problem - I would check and recheck your graphic card is seated properly in it's slot. Sometimes it will take a few attempts to get it right depending on your case and how bent or straight or well designed it all is.

Okay, since it's now not working at all (!!?!?), I will take it out and reseat it.

Thanks again for your help. Here goes nothing. Will report back

Okay...reseated once. Nothing happened. Reseated twice.. nothing. Third time... A CHARM!

Thank you very much for your wisdom. I shall see how it travels over the next few reboots.

Well all is looking good after three reboots!

I don't want to push things too far unnecessarily just yet (eg rebooting just to test the card).

Thanks again for your excellent help and advice. It's worked so far!
