my younger bro bought a new clone computer 2 months back and during the first week of usage the comp restarts randomly regardless of the tasks it is performing. it would even restart on just winamp playing mp3s. we DID NOT OVERCLOCK or underclock it. we tried to find the source of the prob by ourselves: 3Dmark it for overnigth, have updated the bios, reseated the graphics card and cpu, reset cmos, tried the memory in different channels, tried both usb and ps/2 keyboard and mouse, checked the temps are well within spec; we can’t find the source. so we brought it back to the store. ppl there ran test on it and after many test later they manage to get a restart half way through a simulation of a game. the technician said that it was a graphical driver and power thing. the motherboard has an onboard graphic card, C51G graphic chip on it. he recon that we get a better and more powerful PSU and an off board graphic card. we did that and the PC restarted less often, as in once in 3 days? unfortunately i was busy at that time and couldn’t handle the pc stuffs for him (i was his transport and guardian but uni finals comes first). 3 days ago, his comp completely won’t start up with the off board Gigabyte GeForce6600GT. took out the graphic card and enable the onboard chip. the pc restarts on 2 different situation:
- with graphical corruption (the vertical lines on the winfast word) at post screen and it will never get to hit the winXP log in screen. it just froze at the post screen.
- restart it again by reset button. it enters into xp just fine but usually reboot during 20mins or less into usage, regardless of what is running on pc.
we tried many restarts and it’ll alternate between situation 1 and 2. situation 2 is like a more severe version of the initial situation. we couldn’t run 3Dmark on it without it restarting on the instant the program starts…
the specs of the comp is PC2 in my signature:
AMD64 Sempron 2500+, Winfast6100K8MB-RS mobo (with onboard graphic chip based on Geforce 6100GT), Maxtor SATA 120Gb, 512 400MHz Apacer DDR Ram, Liteon SOHW-1653S DVD±RW, Cooler Master 430W, WinXP SP1
…any idea or suggestion as to what is the problem? i’m bringing it back to the store tomorrow to see what can they do about it.
i know there was a thread similar to this, so if it was wrong to create another thread then i’m sorry and the MODs can move or delete this thread.
