Rather unusual problem.
Helping neighbour with elderly computer. Has a reasonable spec. for XP. ASUS M.B.
Intel Core 2 2.1 GHz CPU 2 GB RAM.
Boots up normal, but looks and is best described as if only half the system is functioning. No icons on desktop, all the built in games are ok, Chrome browser will not load, Control panel appears. No network connections. Now the odd behaviour completely changes after approx 10-15 mins. After this time there is some H/D activity and the system is then fully operational.
I have noticed that booting into SAFEMODE everything is functioning immediately.
And to further add to my confusion, I fitted a spare H/D and installed XP. this clean copy also displays similar behaviour.
I tried a new power supply, this made no difference.
Any help with my confusion will be very much appreciated.
