Hi, Thanks for the reply, I don't think Windows is the problem as I had blue screens on vista before I upgraded with W7 full version. This is a cold boot problem because once in Windows I can shut down and if I turn the PC back on within 20 minutes it boots no problem. If turned off overnight i get the BAD_POOL_HEADER blue screen error. I think this is a hardware problem as it occurs even after a full clean install of W7, I am slowly narrowing things down to the following parts: Hard Drive - Brand new and BSOD with old one Motherboard - This is the second one, with both BSOD Power Supply - 700W really new Ram - New, did Memtest86 no errors GFX Card - New, BSOD with the last one CPU - From my last PC, not new but not ancient CD Drive - From my last PC Any ideas? I am certain everything is plugged in and where it should be, all risers in the right place, flashing BIOS doesn't fix it. The ram is listed in the authorised distributers for the motherboard but the C7 version, mine is C9...could the timings be off? I have increased the RAM voltage to working level.

Ok bit of an update, new hard drive installed, so everything in the system is new even windows 7. Did clean install with new hard drive, installed fine and loaded to windows. Didn't install anything more firewalls, drivers etc as I wanted to narrow things down. Turned the PC off and did a restart...no problems. Turned the PC off and left it for 1 hour...blue screen of death when attempting to load windows. Error 0x00000019 BAD POOL HEADER. What is wrong with this newly built machine I don't know, please help.

Once you have found out your power supply you will need to check if it has enough juice to power your new card. This website is helpful: Antec Power Supply Calculator Then once you know you can either buy a new PSU or keep toyour current one. The GTX 460 requires to wires that come from the PSU they both have a connector with 6 holes in them, they are normally wrapped together. You need two to plug into the card.

Hi, All you need to do is enter your Bios 'Press F1 when computer promts you to on first boot' Then in Bios change your boot up order to CD-ROM first option. Then simply turn off the computer turn it back on and insert the windows disk straight away and follow the instructions. It will ask you to partition the drive, so some for OS files and the rest for Data.

The last thing I did before the error was install the new motherboard and RAM. I am not sure if I re-formatted during the windows 7 install as it was a clean install but it showed some partitions in my hard drive and I was confused as to where I should install the new windows. Haven't had a look in event viewer. When I do the system repair it finds no errors and loads windows when I reset but as soon as I turn off the computer overnight the same problem again 'Windows failed to start'

Hi, I had an Acer desktop PC that I purchased about a year ago with Windows Vista pre installed. I was slowly upgrading parts to this computer as I wanted to build my own up-to-date machine. I now have a new: 700w Power supply Asus GTX 460 768MB Graphics card Asus M4A77T Motherboard 4GB DDR3 Geil Memory 1333mhz New copy of Windows 7 Full version All that remains from the old Acer is: 460GB Hard drive DVD/CD Player/Burner AMD Phenom II Quad Core Processor Generic Heatsink The problem is I have installed the new version of Windows 7 which went fine and if I do a restart it boots fine. However if I turn the computer off over night or for more than say 30 minutes it boots up saying: Windows failed to start. This may be due to a recent hardware/software change. 1) Start up repair 2) Normal start Windows repair only asks to do restore which doesn't solve the problem, normal start leads to blue screen. I can go into repair mode then which starts to try and solve the problem, I then press the reset button and it will then give me the options again but normal start takes me into windows without fail, no blue screen. The computer then stays on fine and works, if I put it in sleep mode, fine, restart, fine, turn it off for 30 minutes, problems. Can anyone help me with this as I am wracking my brain.
