Basically I am having some issues with my current PC system. I am using the following hardware:
Intel Pentium Quad Core Q8300@2.5ghz
ATI HD5770 1 Gig GPU
4 Gigs DDR(2) memory
Usual on board sound etc and OS is Windows 7 64 Bit Edition.
So basically I have been having issues with my PC since around Christmas time. The main issue is there appears to be an issue with the memory where my PC will freeze up playing games or watching DVD's on Media Player, or even yesterday, something as simple as opening a new tab in internet explorer. This varies, yesterday the screen would freeze and the sound and then about 20-30 seconds later the screen would come back on and an error message would pop up saying the ATI hardware has crashed but now it is working again. Previous to this I would get blue screen errors where the PC would just freeze up completley. In January I took what I felt was two deffective sticks of memory out of my PC to see if that would work and it did. So I got two gigs new memory to find I had got the wrong speed (533mhz instead of 800mhz I think) and tried that and when using it the PC would fail to boot (the motherboard would beep three or four times and then nothing when booting up). However, my Dad had a look at this yesterday and took the two working memory modules out (2 gigs, 2 X 1 DDR2 at 800mhz) to put in four other sticks (the two new 1 gig ddr2 sticks at 533mhz, and two 1 gig ddr2 memory sticks at 800mhz that seemed to fail at Christmas). This boots up but whenever I play a game or watch a dvd or use Internet Explorer the PC will crash and state the ATI hardware crashed.
This leads to the PC continuing on but in games it can be 30 seconds or less of gameplay and then lock up, forcing me to use control alt delete to open task manager and with some games (CS GO) I can just continue (which is problematic given its an online game so I am stuck in the same place and usually leads me to being killed whilst this crash happens) or some games fail to allow me to continue (Skryim just locked up totally so I had to end task on that one). In Media Player the dvd I was watching stopped but about 30 seconds later would go again but had skipped to the end of the show I was watching so I had to find the place I was at to start again.
This is not the only issue this PC has had, my DVD drives keep breaking where the PC will fail to boot into Windows after a few weeks/months of use unless I unlplug the DVD drive from the motherboard and disable it in the BIOS. This has been happening for well over a year to the point I am using an external USB DVD drive and not had any issue with it since then.
Basically I am using a PC that won't play any games and may crash doing other basic things and has a none functioning internal disk drive.
So essentially, are there any cures I could look into for this? I was thinking maybe I get 2X 2 Gig DDR2 800MHZ memory modules and take all the memory out and use that, but it would not solve the optical drive issue but at least would leave me with a potentially working machine (assuming it is the memory). The other solution I am looking at would be to buy a whole new rig, but I would like some advise (i.e. which is the best budget gaming PC build to buy, given it would need an OS as I am using an OEM version of Windows 7 thus can not install it to a new system entirely, Intel i5 vs i7 vs AMD CPU's, ATI or nVidia series GPU, get a solid state drive for Windows and a normal hard disk, or two normal hard disk drives, good psu suppliers etc).
TLDR version, PC is broke, do I replace parts on it or make a new system?
So what advise can you give me?
