Help with Vista
 

Hey, I just got my computer fixed (replaced Graphics card and power supply). the computer was running perfectly until I downloaded all of the Windows Updates. after the updates were all installed the computer wouldn't boot anymore instead it would come up with "Missing Operation System" or "Disk Read Error"

Computer specs are: ASUS P5N-E SLI, Intel Duo Quad Core, 700w Power Supply (new), Zotac gForce GT5250 (new), 500g HD, 4g Ram.

Like I said the computer was running great until I did all the updates.

I've also just bought a wireless Keyboard and Mouse and they were installed around the same time the computer started being fussy, but they were installed prior to the computer shtting the bed, I've read a that this could be a problem with the boot up

Anyone else have this problem or know how I can fix it?

Do you have a USB drive plugged into the machine? It's booting to something that doesn't have an OS. Check your USB ports first for a USB drive. If you've got more than one hard drive installed, make sure the proper drive is set to boot first.

check bios settings, boot sequence, hdd setup

the only USB plugin are my wireless reciever for my keyboard and mouse and my printer

just checked this apperently my computer was trying to boot from a removable disk, I changed the boot sequence to hard drive computer loaded just fine...

second problem now is when my computer starts getting overloaded it turns its self off, i think i'll be returning this power supply for a 1000w

700W is way more than enough for what you're running. It's possible the PSU is faulty but the problem is not that it's not enough power.

It's more likely that the CPU is overheating. Maybe the heatsink was moved slightly as you were installing the new components and is no longer properly cooling the CPU. Get yourself a temp monitor (Everest, coretemp, realtemp) and post your temps, especially note what it is just before it shuts down. Also what model of CPU is it?

I'm actually back at square one again computer started was running fine, was browsing the web nothing was running heavy computer shut off and now it tells me "DISK READ ERROR"

windows startup says im runnign at 80C which seems really high im not sure its accurate

I'm gonna do a complete reformat and wipe everything. i have 2 computers so ill be checking back here every so often

cant reformat either apperently says "no device drivers were found"

That is VERY high for a CPU not under load. That is likely the cause of your problems and the sudden shutting down may have caused other issues with your HDD or Mobo. Your boot order changing is likely the result of an unintentional CMOS reset and the "no device drivers were found" could be any number of issues. Fix the CPU problem first then address further problems from there.

any idea how to drop the tempature more im running 2 ICute 4" fans the 2 fans on the power supply the intel heat sink fan and the graphics fan i cant think of anything else to do to drop tempature there isnt much room left for me to put anythng else

Your heatsink probably isn't installed properly

exactly. I would recommend just replacing the shitty stock intel one with literally anything else. OCZ Vendetta is a good cheap one. Make sure to get some thermal compound too. If you don't know how to install it properly, google is your friend.

double checked my heatsink i think that is my power problem seams that as soon as it gets hot my puter shuts off, the thermal compound was basically non existant which explains why the heatsink wasnt working properly

mounted another 2 fans had to make a bracket to mount the 2nd one

if it is a stock intel heat sink, you just have to make sure the supports of the 4 corners are secured. did you over clock your CPU?

no i never over clocked the cpu. the computer was built overkill so i didnt have to ever worry about over clocking it

only game i used to play was WoW dont play it much anymore thou

Did you end up getting some thermal compound on the heatsink/CPU? I don't think you need THAT many fans. You just need the heatsink to do it's job effectively (meaning conduct the heat from the CPU to heatsink). Airflow from the fans in your case and heatsink should do the rest.

I'd do that part first and would advise NOT to turn on your computer again until you've done the thermal compound. You'll risk damaging your CPU from all that heat if you keep turning it on.

BTW, if you've never applied thermal compound before, you don't need so much on the CPU that it oozes out the sides. A relatively thin layer (spread it around with an old credit card or business card) so that it's enough to fill in the small gaps between the CPU and heatsink is enough.
