.... picking up from your other thread with thcbytes
Check in Device Manager
for any yellow exclamation marks indicating a problem with drivers.
What drivers have been loaded? Have you loaded the motherboard drivers from the Gateway web site? Graphics card drivers? Others?
How did you install XP on the SATA hard drive? Did you install the SATA drivers first or alter the BIOS configuration first to enable the XP installation disk to see the SATA hard drive?
Ensure that the inside of the box is clean: Blow it out with compressed air .... including the power supply. Ensure that ventilation is good.
You have mentioned that you have three hard drives. (I note that you have already run the Hitachi DFT on your system hard drive.)These should all be tested with the hard drive manufacturer's diagnostic utility. You should also run chkdsk /r
(the same as "Error checking with both boxes ticked) on each drive. You should also examine the S.M.A.R.T. characteristics of each hard drive.
If the S.M.A.R.T. characteristics are not displayed in the DFT test, you can download and use HD Tune http://www.hdtune.com/download.html
(not the Pro version which you would need to pay for) to further test the hard drives and display the S.M.A.R.T. characteristics.
(IMPORTANT: Do not neglect to to run the above tests on your other hard drives)
=================STRESS TESTING or STABILITY TESTING of the system.
I recommend the following guide (I use these tests on the computers that I put together for my own use)Guidelines for Thorough Stability Testinghttp://www.overclockers.com/forums/showthread.php?t=335813
Step 1. (some extra notes)
) from the following link (archived versions of Prime95):ftp://mersenne.org/gimps_archive/archived_executables/p95v2414.exe
(Using this older version of Prime95 will allow you to follow the instructions in the Stability Testing article: The later versions are a little different and cannot be configured as outlined in the article.)
Also test with Toasthttp://majorgeeks.com/Toast_d867.html
at the same time monitoring the CPU temperature with a program such as Motherboard Monitor 5http://majorgeeks.com/Motherboard_Monitor_d311.html
or Speedfan http://www.almico.com/speedfan.php
Run Toast for 20 minutes while watching the CPU temperature. This will test the effectiveness of your cooling system.
(You have said that you have completed this test already, but have you let it run for 24 hours?)
If the result of all that testing is good .... then I would say you can proceed to use your system with confidence
. Visit Windows Updates until there are no more updates available. Install an antivirus program .... and some other security features, if you are that way inclined .... and you are right to go.
Any questions ... ? Fire away!
