that makes absolutly no sense.
how do you figure "swapping" your system components from one case to another set your drivers to windows default. the drivers are installed in the OS on the hard drive...without reinstalling windows or uninstalling a device (such as your video card) in the device manager the OS would keep the same video driver active. unpluging a drive is not enough to get windows to change configuration/registry entries etc....
Good question. Everytime I've reseated my graphics card, the drivers that were on the system have been reset. It's happened twice already.
ya that is not normal. It should only be doing that if you seated the video card in a different slot. I have removed and reseated many video cards, unplugged and reconnected many hdds and never seen this happen. Wierd!
my question is, after you got everything swapped into the new case did you get a "new device found" message of windows telling you it found your video card? if not then your video card was not lost/uninstalled from the OS which means the drivers should not have been rolled back to windows default.
And yes I got the new drivers found message. It's happened twice. Once when I swapped my case (I did have to take everything apart.) And once when I was reseating my GPU. It would not let me take screen shots with the Windows found drivers but it worked fine after I manually DLed them through nvidia.
ditto on the above, makes me wonder what is causing it.
My computer passes QAWin32 and PC-Check System Check hardware diagnostics. if I turn my computer off or reboot, my computer will not post. I'll have press the power button a thousand times and it'll eventually go through. It worked immediately after reseating my GPU (that's how I discovered that the second time) and a few times I had to reapply thermal paste and reseat my heat sink before it would turn on. You figure that one out for me, then I'll love you.
not POSTing huh? have you tried disabling quick POST in the BIOS to allow the system to run ALL POST tests? if not give it a shot, it might find something.
have you tried clearing the CMOS or flashing the BIOS?
clearing CMOS is easy, your mainboard manual should have directions, most boards have a jumper for it (sometimes labled on the board as CLR CMOS or just plain CMOS) , power off system and turn off or unplug power supply then switch the jumper for 5-10 seconds. will set the bios back to factory defaults and if you have tweeked anything you will have to redo your tweeks.
if no jumper...power off and unplug power supply, then remove the battery for 30 seconds.
you may need to flash the BIOS.
1. backup current bios if possible.... alot of boards today come with dual bios or bios back up options, save the current BIOS to the backup or second bios, some will even allow you to save to a floppy and thus have a utility in the bios to do so and restore from the floppy.
2. search manufac site for BIOS updates and any flashing utility (should either be included in bios zip file or be a separate download in the same area)
3. FOLLOW MANUFACTURER DIRECTIONS EXACTLY for flashing.
it is usually recommened that you print the BIOS flashing directions from the site so you have them to refer to during flashing...DO IT, YOU WILL PROBABLY NOT REMEMBER EVERY STEP EXACTLY AND ONE MISTAKE CAN BE DISASTER.
if not any of this then I would have to say you have some sort of hardware problem that your testing utilities is not catching, really they may not see all problems such as problems that are stopping you from booting, because they are testing a system that is booted, therefore if what ever the problem is happens to be working at the time the test will pass.
perhaps you have a stick of RAM playing hit or miss trying to die, try booting with only one stick at a time until you test every stick, if you get a no boot that stick is bad.
or maybe you have a small crack in your mainboard or on a trace (the copper/gold lines) or another mainboard problem, or have a power connector problem, any of these will cause shorts and stop post/boot
how old is your Power supply and how big is it, what is your system config, you may be having PSU issues.
my daughters computer was acting similar a couple yrs ago (booted when it felt like it), it turned out that the 20 pin power connector was lose/cracked solder and shorting out. holding it down would boot, otherwise it was hit or miss.
are you getting any random crashes?
you may want to take it to a local tech for extensive hardware testing.
