My pc has been poorly for a while and i am not fully convinced its better..basically after about a week of re-instal it bombs and no recovery was possible
After about 6 installs i got a copy of hirens boot disc 7.7 [search for it ,its free] did a hard drive test and it was broken with bad sectors. So i got another drive but not before a new power supply as i thought this was problem. New drive in about a week and it seemed great..then one day i left pc for an our came back and it was at the boot screen..again no recovery possible.
I thought hard drive dead but pc shop fixed it and i now have it running again

they told me to download a windows memory test utility from the windows site. I have done this and created a boot floppy which has tested memory and all is ok,i have also ran tests from hirens boot cd which has tested.
Memory [to be sure 3 tests] ......All OK
Hard drive........OK but i loaded old drive on as slave and seagate tool found bad sectors the tool fixed this so i am using it for back up until i get another.
Motherboard...Some tests were over my head but generally ...All ok
I ran a stress test...All ok!
I have now left the side of my case off for a while as since i have added a Radeon 9800pro and i Audigy sound card things are getting cluttered in there!
I am hoping failures are heat related ventilation in case is pretty crap so if all runs well for a month i will modify case to improve this.
As a safeguard i have used hirens tools to clone my drive i never done this before but if this sounds right i have cracked it.
On my new drive C: i have original operating system and on backup slave drive D: i have the clone, to test i booted into bios and changed boot order disabling new drive [HDD-0] and enabling old drive [HDD-1] all seems good.Hopefully if it goes tits up again i can just boot from clone drive rather then re-install from scratch again.
I know cloning to a dodgy drive isn't the greatest idea but its only temporary until i can get a new drive.Hope this helps someone

Oh..one more thing if you copied over 98 thats not good you need to re-format and install xp fresh!
1.Enable boot from rom in bios
2.put xp disc in rom drive and shut down.
3. when asked to boot from rom press enter key
4.let Windows load
5.When prompted were to install select C:drive [unless you have 98 on a different drive then choose that!]
6.you will be told its not good to install with an existing operating system and offered to re-format press the arrow keys to highlight drive [ensure you select the nfts file system] with 98 on and then press F key
7.It will re-format then re-boot
8.You will be guided through installing Windows xp
