as the title says, anyway I try to boot up this pc, it freezes everytime i just cant work out why.  Its a hp slimline s3380a with Vista.  hdd had bad sectors originally a few weeks ago so replaced and reinstalled vista from MS vista sp2 oem dvd, all went ok.  ran ok for a couple days then some times would not start, froze on loading vista screen, scrolling bars froze, other times it worked.  Now it freezes in same position everytime I try to start.  Strangely enough, the scrolling bars on loading vista screen freeze immediately after the three keyboard lights flash, then its unresponsive, have to hold power in for 5 secs to switch off.  I have tried removing all the devices, disconnecting all internal headers inc usb/sound except for power buttton, resetting bios, testing ram, the list goes on.  Have tried booting from an ubuntu 9.10 desktop live cd, freezes up shortly after boot.  Tried booting xp pro cd, freezes after loading all the startup drivers.  Tried booting vista dvd, same scenario and freezes after loading startup drivers.  No capacitors on the motherboard have popped out.  Now im assuming the motherboard is faulty.

Yeah it sounds like you have a damaged mobo.
The only other way to test is if you have a couple of sticks of ram, try using one at a time.
Ram can be very temperamental ie: work in one PC and not another.

Also try a different power supply if possible.

Check for cap damage (or leaks) on the MB too.
As above try a single bank of ram if supported by the system, also try each ram bank slot one at a time.

If all else fails try a new MB .. $80-$160ish, Ram same price range.

Cheers

will try different ram and see what happens.  As for the power supply, its a non generic psu, is long and goes lenthways down the side of the case, has a small size atx connector to the mainboard.  If im going to try a different psu will need to obtain some sort of atx mobo plug converter.

If the MB has standard ATX style connections, You should be able to use any modern powersupply for testing.

Just be careful with the case off and the power supply on the loose, you dont want it to drop in and short anything out.
