I really hope someone can help me here as i am at my wits end.
I installed a new MoBo + HDD and DVD drive , to begin with I had an error message
"NTLDR" is missing press ctrl , alt + delete to restart. So after some advice from another post I stripped it down and re-installed everything again and hey PRESTO I no longer get the error message but my problem is that the computer still switches off after about a minute but previously before i stripped it down the computer was switching off after about 30 seconds.I don't even get a chance to install my XP O/S
I have checked all cables and connectors are secure to no AVAIL.The computer will start to install the O/S and then cut off after about a minute.

Any help would be most appreciated
Many thanks in advanceReseat the memory and make sure it's in there good. Then try running a memory test to see if ONE of your memory modules is bad.The power supply could be bad.I tried removing the ram (i've got 2 sticks of 1Gig ram brand new - team elite gaming ram) and put 1 in at a time and in the different banks to no avail and the PSU is only a couple of months old.
There was no problems with the computer switching off before the new hardware was installed.

Check your cpu fan, heat sink fitment & thermal paste.

Go into BIOS and check your temps, stay there for a while and see if it shuts down.
