Three years ago my mom needed a new computer. I wanted to build her one but my dad refused to go that route and so while doing research for them Staples had a nice bundled HP system that some of the people I knew quite well who worked at this particular store said it was a good system. This is what I remember about it: Asus motherboard, E4300 Intel dual core @1.8 GHz, 2 gigs of DDR memory, and Vista 32-bit. Well she has been having serious freezing issues and other things happening. Below is what she wrote me in that I'll put in blue: Before Staples: PC keep locking up. Would not turn off or respond to any commands. Had to pull power plug in and out to kick up it several times than PC would turn on and work but froze during operation. Took it five times to Staples. Each time a virus was found even though they ran a diagnostice test and removed virus. 5th time, Staples ran a day long diagnostic only to find that it proved that NORTON was the reason for freeze. Took too much room and wouldn't let computer work. Replaced Norton with Kaspersky. Staples said last time that the PC was probably having other failures and it doesn't pay to bring it back. They suggested a new computer After Staples:Works great [after doing some disc clean-up that she can't remember exactly what she had done :rolleyes: ]. But getting it turned on some times requires these steps. 1. Won't start on first try. Moniter shuts down. 2. After I turn it off than I hold the on button down for about 30 seconds, PC comes on. I put in password, get the screen for the safe mode or normal start. 3. I click on safe mode, files are installed, than I put in pass word. 4. Windows is LARGE. Have to restart then it comes back normal size after I type in pass word and everthing works GREAT. While I use the computer a lot, a couple of times it froze but has been working great but one never knows when it will freeze and even the mouse won't work and/or the keyboard. I had to pull the power plug to unfreeze it and it worked. My folks live 2 and half hours away in another state but come this Monday I have a meeting that will enable me to get to their house in 15 minutes which will give a whopping one and half hours to do as much diagnostic work as I can before I have to get on the road. Here is what I plan on doing: 1. Test the power supply with a multimeter. 2. Check Event Viewer and Run CheckDisk 3. Because it is an HP the BIOS will only let me do certain things. I would want to do at least a S.M.A.R.T. test and memory but I believe I am blocked from doing so. 4. Check the SATA cables/all cabels. [U]So Here is my question:[/U] Since I only have an hour and half for diagnostics what would you think is the most important things I should do and what would you suggest that I haven't listed? Thanks!
