PLEASE HELP!! I just purchased this Barebone Computer Kit from Tiger Direct to replace my wife's laptop which is dying. I finally have all the parts to assemble it and start it up. When I purchased the kit "Online" it was sold as a "All Systems Tested and Fully Compatable System".
I was having problems cold booting this computer for the first time. I have now resolved that issue and found the source of the problem in the bootup process itself. Evidently all is not well and fully tested and compatable as Tiger Direct says it is. As the computer boots up for the very first time, you have only 3-4 minutes to tell it weather or not to proceede with installing the following message. I have taken the time to copy the message exactly as it is displayed on my computer screen. I of course will be calling Tiger Direct's Tech Support Line. I have found them to be only as good as the person who answers the phone. Being I'm green anyhow and won't know weather or not I'm being feed a line of BS or not, I thought I'd get some other opinions from folks who understand Computers far better than I. I'm simply firefighter who is trying to buy his wife a decent computer without spending an arm and a leg. In fact I thought this thing would arrive already assembeld and all I needed to do was add an OS and some extras, like a decent video card. I never intended to  build this thing from scratch, I could have purchased a simular spec'd Gateway complete with OS preinstalled with a warrenty for less money!!! I'm Not Happy and Not a Techie!! But looking on the bright side, I sure am learning a lot about computers! If I can get it to work without too many more problems I will be very happy.
When the computer first boots, here is the message that appears on the screen;
AMIBIOS C 2005 American Megatrends Inc
BIOs Date 8/25/06 24:17:51 Ver A7255VMS V1.0
Intel Pentium 4 CPU 3.00GHz Speed 266x12 =3200
Hyper Threading Enabled
DDR2 Speed 533MZ
A 200 MHz System Bus Processor is Installed
This Processor Is Not Supported On This Board And Will Run At A Reduced Processor Clock Speed. System Performance Will Be Impacted.
Do You Wish To Continue To Boot @ 266MHz
System Bus And Reduce Processor Speed (Y/N)
Press (Y) To Continue (N) to Shut Down
If I press the Y the computer will run and not shut off in 3 minutes. I let it run last night to see what would happen?? Would it burst into flames?? Would it shut down?? Well after a hour it shut down. Is that normal? Is it some kind of saftey mechinism?
It will start right up again, but it was almost 5am so I shut er down and went to bed. I'm waiting for some advice before I move forward from here. Please respond ASAP! I'd like to get this thing done so I can move on to the next 'Honey Do' project.
This is my first computer I have ever built so I am green to all this. I dont really understand what all this means and what kind of an impact will this have on my new computer??
1. What does this mean, my CPU is not compataible to this board?
2. If I keep it and install it, will it cause the computer to be unstable latter on?
3. How much of a negitive impact will this have on my computer?
4. How much will it slow it down?
5. What would you do if you were in my shoes? Replace the CPU for the right one or upgrade to a better one or keep it??
6. If I do upgrade, what would be a better choice and not break the bank??

Answer 1

:no-idea: Thanks Dry Heat,
I went to the link that you provided. Here is the latest problem...... I can get the computer to run longer than 3 minutes by pressing the Y key when asked during the initial boot-up. After that the computer will not move off that window I described in my 1st post, no matter what I do. I tried restarting the computer and pressed the Delete key to see if that would work and the F1 and F2 keys during the initial boot up, the Bios Window would appear but the computer would shut down, there was nothing I could do to get past this, let alone go on-line to download something. How would I get on-line without an operating system to update the Bios? Remember I am Green and have no idea what the heck I'm doing, let alone what is the real problem here. Its like fighting fire blindfolded! Please help and be detailed on how I should procede. Thanks! Woody
